Basic Care Guide
Water
Damask rose favors moist but not water-logged conditions, so it's important to keep the soil well-drained whether it's planted in the ground or potted. When growing outdoors, it can be watered when the soil surface is slightly dry (except for in winter) with no fixed watering frequency. Keep the soil moist, as drought will reduce the number of flowers.
In drought, the plant needs to be watered every 2-3 days. Pay attention to drainage and avoid water-logging during the rainy season. Winter is its dormant period, so it's okay to stop watering then. The plant is not tolerant of water-logging; its roots easily rot. Avoid water accumulation when watering, and also avoid splashing water onto the leaves to prevent disease.
Potted damask rose can be watered every 2 days during the growing season except for winter. Only water the plant when the soil surface is slightly dry. In high-temperature seasons, the evaporation of water increases, and the plant is in a weak and semi-dormant period. To prevent it from drying out, water it twice a day in the morning and at night. Additionally, avoid too much exposure to sunlight.
It’s recommended to water potted plants until excess water seeps out from the bottom of the container. Remember to drain the standing water, or place a saucer with pebbles under the pot to allow excess water to flow out easily. During the dormancy period in winter, it should be watered less often. Only water often enough to prevent the soil from becoming extremely dry. Damask rose needs to be watered more from budding to flowering, and the amount and frequency of watering should be reduced after flowering.
Never miss a care task again!

Fertilizer
Damask rose favors fertile soil, so it's best to apply fertilizer several times during the growing season, but only in small amounts each time. In the spring and summer, you can use liquid fertilizer twice a month and use slow-release fertilizer every two months. Add more nutrients for more lush plants and flowers. A slow-release organic fertilizer can be used in winter so the new shoot and buds in next year's bloom will be lush; these flowers will be large and gorgeous.
If damask rose is to be used for fresh-cut flowers, fertilize them 1-2 times a week during the florescence. Pay attention to the cultivation of branches with flowers. Cut off flower buds from weak branches of the plant to concentrate nutrients in the stronger ones. Additionally, a sprinkling of Mycorrhizal fungi (which is also sold as Root Grow) at the base of the plant will allow the beneficial fungi to form a symbiotic relationship with the root system, helping it to absorb nutrients and water.
Sunlight
Damask rose favors full sun and also can tolerate a half shade environment. In partial shade, it usually only grows leaves and does not bloom. Even if it has flower buds, the flower is neither gorgeous nor fragrant. As a result, it is recommended that gardeners ensure sunlight at least 6 hours per day during the growing season (but not necessarily in winter). In summer, it should be appropriately shaded to prevent overexposure to sunlight.

Pruning
Damask rose has a strong sprouting ability and grows luxuriantly. Without proper, timely pruning, it will attract diseases and pests in hot, humid, insufficiently lit, or poorly ventilated conditions. After the first bloom, the plant should be slightly pruned. Promptly cut off faded flowers and thin, overlapping branches, leaving only young and strong branches. During winter dormancy, careful pruning is recommended.
Advanced Care Guide
Temperature
Damask rose is widely distributed from cold temperate zones to tropical areas. It likes cool, ventilated environments and is not tolerant of high temperatures. The optimum temperature range is 15 to 26 ℃. Some species can tolerate temperatures as low as -26 ℃ and high temperatures of up to 35 ℃. When the temperature is below 4 ℃ in winter and above 30 ℃ in summer, the plant becomes semi-dormant and has poor growth. The flowers during this period will have a few small, white petals with a dim and lusterless color and are not good-looking at all.
Damask rose favors moist conditions but is not resistant to water-logging. It can tolerate moderate drought. Provide more water from budding to flowering, but reduce watering after blooming time. After blooming, wait to water again until the soil is basically dry to avoid any accumulation. Ensure good ventilation and drain excess water during the rainy season to prevent damage to its roots.
Soil
Damask rose can adapt to a variety of soil types and grows best in acidic soil which is fertile, loose, and water-drained. When planting in the garden, you should choose a place on higher terrain with sufficient sunlight, good air ventilation, and slightly acidic soil. Planting in high terrain helps avoid water accumulation in soil. Before planting, deeply loosen the soil and use organic fertilizer as base fertilizer. If planting as a potted plant, use humus-rich and slightly acidic sandy soil.
Propagation
Planting
Harvest
Damask rose can be propagated by grafting. Multiflora rose (Rosa multiflora) is often used as rootstock for grafting. Generally, grafting is carried out from the end of summer to the beginning of autumn, and the grafting part is as close to the ground as possible. Cut a T-shaped cut on the outer skin of the rootstock with a knife on one side of the stem and branch, then select a bud from the middle of a well-developed branch in the same year, cut the bud with bark, insert it into the T-shaped cut, bind it with plastic film, and place it in proper shade. It can usually be untied 15 days after grafting, and will germinate and survive after 30 days.
You can also select a branch that has not yet developed a leaf bud as a scion if the thickness of the scion is more similar to that of the rootstock. Cut a 2 cm deep cut on the rootstock longitudinally, insert the scion into the cut, and then fasten it with plastic film. The incision will heal after about 10 days.
Damask rose can also propagate by division. It can be planted deeper and filled with soil to the roots so that new roots can grow at the bottom of each branch. In the early spring or late autumn, the whole plant can be dug out with soil to be divided into ramets. Select a stem with 1-2 branches and some fibrous roots, and then separate it from the whole plant and plant it in a basin or garden. At the same time, prune the branches on the ground to reduce the evaporation of water and improve the survival rate of transplanting.
Cutting propagation, another useful way to propagate damask rose, is generally carried out in spring and autumn. Branches with 3-4 buds can be cut off to use. The substrate for cutting can be a mix of river sand, rice chaff ash, or vermiculite, etc. Insert the branches into the substrate, shade it properly, and spray to maintain humidity. The branches will take root 20-30 days after cutting, and the survival rate is 70-80%. If the branches are dipped in rooting powder and then inserted into the substrate, the survival rate will be higher. Additionally, the cuttings can be immersed in water for cutting; the cutting temperature is 20 to 25 ℃, and new roots will grow after 20 days.
If planting potted damask rose in your garden, it's best to find a suitable site with adequate sunlight, fertile soil, good drainage, and preferably a place that hasn't been planted with any roses before. A field that previously grew roses may increase the probability of infection. Transplanting can be done in all seasons except winter.
First, dig a pit that is twice as big as the flower pot. Add a small amount of base fertilizer to the pit, and place the root system or rootball into the pit so that the root crown (where the aboveground part and the underground part connect) is at or slightly higher than the surface of the soil. Backfill and slowly compact the soil. A layer of organic mulch can be used to cover the soil surface for heat preservation of roots and also reduce the growth of weeds. Water thoroughly after transplanting and water often in the first week to avoid wilting caused by a lack of water.
If transplanting damask rose from one part of the garden to another, do it in fall to avoid the cold of winter. Water the plants three days before transplanting; this makes it easy to dig up and retain the rootballs. Then, trim off the overlong branches and excessive leaves, leaving 3-4 branches per plant to reduce excessive consumption of nutrients and ensure its survival. Prune any unhealthy roots left after being dug up.
If a bare-root rose cannot be immediately planted after purchase, it can simply be placed into a pit and covered with soil. If it has already gone without water for some time, it's better to soak its roots in water for half an hour before planting to help it recover. It is recommended to plant bare-root roses in gardens in the fall.
Damask rose produces excellent fresh flowers that can be pruned with sharp scissors as soon as they bloom. It is best to pick flowers in the morning to avoid loss of water through plant transpiration at noon. After picking, it is necessary to trim the base of the branch at a 45° angle to increase the water absorption area. Quickly put the flower into a vase with clean water to avoid water loss.
Seasonal Precautions
In warm and humid seasons such as spring and summer, various diseases and pests commonly occur. Drugs that can be used in advance to prevent the plant from getting sick are recommended. Pruning in time after flowering and before entering winter can also help plants reduce unnecessary nutrient consumption and grow better with concentrated nutrition.

Common Pests & Diseases
Common issues for Damask rose based on 10 million real cases
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Solutions: Some steps to take to address black spot include: Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves. Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash. Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil. Use a spreader in the fungicide spray to ensure better coverage.
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
- Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
- Placement is often random and scattered as diseases are spread through raindrops.
- May appear on lower leaves and the interior of the plant where humidity is higher.
- Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
- Leaf margins may turn yellow.
- Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
- Blotches grow in size until the entire leaf is brown.
- The leaf falls off the plant.
Severe Symptoms
- Partial or complete premature defoliation
- Reduced growth
- Increased susceptibility to pests and other diseases
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
- Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
- Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
- Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
- Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
- Maintain good air movement between plants through proper plant spacing.
- Increase air circulation through the center of plants through pruning.
- Thoroughly clean all pruning tools after working with diseased plants.
- Never dispose of disease plant material in a compost pile.
- Avoid overhead watering to keep moisture off of the foliage.
- Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
For less serious cases:
- Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
- Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
- Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
To prevent infestations of leaf beetles, follow these practices.
- Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
- Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
- Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
- Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Overview
Black spot is a fungus that largely attacks leaves on a variety of ornamental plants, leaving them covered in dark spots ringed with yellow, and eventually killing them. The fungus is often simply unsightly, but if it infects the whole plant it can interfere with photosynthesis by killing too many leaves. Because of this, it is important to be aware of the best methods for preventing and treating this diseases should it occur in the garden.
Symptom Analysis
Here are a few of the most common symptoms of black spot:
- The plant has developed small black spots along the leaves.
- These spots be small, circular, and clustered together, or they may have a splotchy appearance and take up large portions of the leaves.
- The fungus may also affect plant canes, where lesions start purple and then turn black.
- The plant may suffer premature leaf drop.
Though most forms of black spot fungus pose little risk to a plant's overall health, many gardeners find them unsightly. Severe cases can also weaken a plant, so it becomes more susceptible to other pathogens and diseases.
Disease Cause
Black spot is spread by various types of fungi, which differ slightly depending on whether they are in their sexual or asexual stages.
The fungal spores linger over the winter in fallen leaves and lesions on canes. In the spring, the spores are splashed up onto the leaves, causing infection within seven hours of moisture and when temperatures range between 24 to 29 ℃ with a high relative humidity.
In just two weeks, thousands of additional spores are produced, making it easy for the disease to infect nearby healthy plants as well.
There are several factors that could make a plant more likely to suffer a black spot infection. Here are some of the most common:
- Exposure to infected plants or mulch (the fungus overwinters on dead leaves)
- Weakening from physical damage, pest infestation or other infections.
- Increased periods of wet, humid, warm weather – or exposure to overhead watering
- Plants growing too close together
Solutions
Some steps to take to address black spot include:
- Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves.
- Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash.
- Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil.
- Use a spreader in the fungicide spray to ensure better coverage.
Prevention
Here are a few tips to prevent black spot outbreaks.
- Purchase resistant varieties: Invest in fungus-resistant plant varieties to reduce the chances for black spot diseases.
- Remove infected plant debris: Fungi can overwinter in contaminated plant debris, so remove all fallen leaves from infected plants as soon as possible.
- Rake and discard fallen leaves in the fall.
- Prune regularly.
- Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback. Adding a layer of mulch to the soil will also reduce splashing.
- Grow plants in an open, sunny locations so the foliage dries quickly.
- Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation.
- Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.

Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
- Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
- Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
- Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
- Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
- Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
- Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
- Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

More About Damask Rose
Find your perfect green friends.
Plan your green oasis based on your criteria: plant type, pet safety, skill level, sites, and more.
Common Problems
Why is my damask rose not blooming?
Damask rose needs enough sunlight and nutrients to bloom. Without sufficient light, it seldom grows flower buds. If it has buds but does not bloom normally, it is usually due to a lack of nutrients. Granular fertilizer and foliar fertilizer can be used at the same time to rectify this. Smaller buds on the same branch can also be removed, leaving only 1-2 of the largest buds so as to concentrate nutrition and avoid excessive nutrient consumption. Additionally, some varieties only bloom in spring, while others also bloom in fall and even in summer. Therefore, it is necessary to pay attention to the varieties you planted.
Why do my damask rose leaves turn yellow?
Yellow leaves can have many causes. It may be a natural phenomenon, in which case there is no need to worry. Or, it may be due to improper fertilization like excessive fertilizer concentration. This requires a lot of water to irrigate and wash the flower soil or may require replacing it with new soil to alleviate the problem. Yellowing may also be due to excessive rainfall, too much soil moisture, or root system damage, for which you can slightly loosen the soil to accelerate water loss. There may also be too much sunlight, which burns the leaves. In this case, you need to cut off the burned yellow leaves first, then provide proper shade for the plant. For example, you can move a potted rose to a shady corner, or set up a shading net for roses planted in the garden.

Basic Care Guide
Water
Damask rose favors moist but not water-logged conditions, so it's important to keep the soil well-drained whether it's planted in the ground or potted. When growing outdoors, it can be watered when the soil surface is slightly dry (except for in winter) with no fixed watering frequency. Keep the soil moist, as drought will reduce the number of flowers.
In drought, the plant needs to be watered every 2-3 days. Pay attention to drainage and avoid water-logging during the rainy season. Winter is its dormant period, so it's okay to stop watering then. The plant is not tolerant of water-logging; its roots easily rot. Avoid water accumulation when watering, and also avoid splashing water onto the leaves to prevent disease.
Potted damask rose can be watered every 2 days during the growing season except for winter. Only water the plant when the soil surface is slightly dry. In high-temperature seasons, the evaporation of water increases, and the plant is in a weak and semi-dormant period. To prevent it from drying out, water it twice a day in the morning and at night. Additionally, avoid too much exposure to sunlight.
It’s recommended to water potted plants until excess water seeps out from the bottom of the container. Remember to drain the standing water, or place a saucer with pebbles under the pot to allow excess water to flow out easily. During the dormancy period in winter, it should be watered less often. Only water often enough to prevent the soil from becoming extremely dry. Damask rose needs to be watered more from budding to flowering, and the amount and frequency of watering should be reduced after flowering.
Never miss a care task again!
Plant care made easier than ever with our tailor-made smart care reminder.
Fertilizer
Damask rose favors fertile soil, so it's best to apply fertilizer several times during the growing season, but only in small amounts each time. In the spring and summer, you can use liquid fertilizer twice a month and use slow-release fertilizer every two months. Add more nutrients for more lush plants and flowers. A slow-release organic fertilizer can be used in winter so the new shoot and buds in next year's bloom will be lush; these flowers will be large and gorgeous.
If damask rose is to be used for fresh-cut flowers, fertilize them 1-2 times a week during the florescence. Pay attention to the cultivation of branches with flowers. Cut off flower buds from weak branches of the plant to concentrate nutrients in the stronger ones. Additionally, a sprinkling of Mycorrhizal fungi (which is also sold as Root Grow) at the base of the plant will allow the beneficial fungi to form a symbiotic relationship with the root system, helping it to absorb nutrients and water.
Sunlight
Damask rose favors full sun and also can tolerate a half shade environment. In partial shade, it usually only grows leaves and does not bloom. Even if it has flower buds, the flower is neither gorgeous nor fragrant. As a result, it is recommended that gardeners ensure sunlight at least 6 hours per day during the growing season (but not necessarily in winter). In summer, it should be appropriately shaded to prevent overexposure to sunlight.

Pruning
Damask rose has a strong sprouting ability and grows luxuriantly. Without proper, timely pruning, it will attract diseases and pests in hot, humid, insufficiently lit, or poorly ventilated conditions. After the first bloom, the plant should be slightly pruned. Promptly cut off faded flowers and thin, overlapping branches, leaving only young and strong branches. During winter dormancy, careful pruning is recommended.
Advanced Care Guide
Temperature
Damask rose is widely distributed from cold temperate zones to tropical areas. It likes cool, ventilated environments and is not tolerant of high temperatures. The optimum temperature range is 15 to 26 ℃. Some species can tolerate temperatures as low as -26 ℃ and high temperatures of up to 35 ℃. When the temperature is below 4 ℃ in winter and above 30 ℃ in summer, the plant becomes semi-dormant and has poor growth. The flowers during this period will have a few small, white petals with a dim and lusterless color and are not good-looking at all.
Damask rose favors moist conditions but is not resistant to water-logging. It can tolerate moderate drought. Provide more water from budding to flowering, but reduce watering after blooming time. After blooming, wait to water again until the soil is basically dry to avoid any accumulation. Ensure good ventilation and drain excess water during the rainy season to prevent damage to its roots.
Soil
Damask rose can adapt to a variety of soil types and grows best in acidic soil which is fertile, loose, and water-drained. When planting in the garden, you should choose a place on higher terrain with sufficient sunlight, good air ventilation, and slightly acidic soil. Planting in high terrain helps avoid water accumulation in soil. Before planting, deeply loosen the soil and use organic fertilizer as base fertilizer. If planting as a potted plant, use humus-rich and slightly acidic sandy soil.
Propagation
Planting
Harvest
Damask rose can be propagated by grafting. Multiflora rose (Rosa multiflora) is often used as rootstock for grafting. Generally, grafting is carried out from the end of summer to the beginning of autumn, and the grafting part is as close to the ground as possible. Cut a T-shaped cut on the outer skin of the rootstock with a knife on one side of the stem and branch, then select a bud from the middle of a well-developed branch in the same year, cut the bud with bark, insert it into the T-shaped cut, bind it with plastic film, and place it in proper shade. It can usually be untied 15 days after grafting, and will germinate and survive after 30 days.
You can also select a branch that has not yet developed a leaf bud as a scion if the thickness of the scion is more similar to that of the rootstock. Cut a 2 cm deep cut on the rootstock longitudinally, insert the scion into the cut, and then fasten it with plastic film. The incision will heal after about 10 days.
Damask rose can also propagate by division. It can be planted deeper and filled with soil to the roots so that new roots can grow at the bottom of each branch. In the early spring or late autumn, the whole plant can be dug out with soil to be divided into ramets. Select a stem with 1-2 branches and some fibrous roots, and then separate it from the whole plant and plant it in a basin or garden. At the same time, prune the branches on the ground to reduce the evaporation of water and improve the survival rate of transplanting.
Cutting propagation, another useful way to propagate damask rose, is generally carried out in spring and autumn. Branches with 3-4 buds can be cut off to use. The substrate for cutting can be a mix of river sand, rice chaff ash, or vermiculite, etc. Insert the branches into the substrate, shade it properly, and spray to maintain humidity. The branches will take root 20-30 days after cutting, and the survival rate is 70-80%. If the branches are dipped in rooting powder and then inserted into the substrate, the survival rate will be higher. Additionally, the cuttings can be immersed in water for cutting; the cutting temperature is 20 to 25 ℃, and new roots will grow after 20 days.
If planting potted damask rose in your garden, it's best to find a suitable site with adequate sunlight, fertile soil, good drainage, and preferably a place that hasn't been planted with any roses before. A field that previously grew roses may increase the probability of infection. Transplanting can be done in all seasons except winter.
First, dig a pit that is twice as big as the flower pot. Add a small amount of base fertilizer to the pit, and place the root system or rootball into the pit so that the root crown (where the aboveground part and the underground part connect) is at or slightly higher than the surface of the soil. Backfill and slowly compact the soil. A layer of organic mulch can be used to cover the soil surface for heat preservation of roots and also reduce the growth of weeds. Water thoroughly after transplanting and water often in the first week to avoid wilting caused by a lack of water.
If transplanting damask rose from one part of the garden to another, do it in fall to avoid the cold of winter. Water the plants three days before transplanting; this makes it easy to dig up and retain the rootballs. Then, trim off the overlong branches and excessive leaves, leaving 3-4 branches per plant to reduce excessive consumption of nutrients and ensure its survival. Prune any unhealthy roots left after being dug up.
If a bare-root rose cannot be immediately planted after purchase, it can simply be placed into a pit and covered with soil. If it has already gone without water for some time, it's better to soak its roots in water for half an hour before planting to help it recover. It is recommended to plant bare-root roses in gardens in the fall.
Damask rose produces excellent fresh flowers that can be pruned with sharp scissors as soon as they bloom. It is best to pick flowers in the morning to avoid loss of water through plant transpiration at noon. After picking, it is necessary to trim the base of the branch at a 45° angle to increase the water absorption area. Quickly put the flower into a vase with clean water to avoid water loss.
Seasonal Precautions
In warm and humid seasons such as spring and summer, various diseases and pests commonly occur. Drugs that can be used in advance to prevent the plant from getting sick are recommended. Pruning in time after flowering and before entering winter can also help plants reduce unnecessary nutrient consumption and grow better with concentrated nutrition.

Common Pests & Diseases
Common issues for Damask rose based on 10 million real cases
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Solutions: Some steps to take to address black spot include: Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves. Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash. Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil. Use a spreader in the fungicide spray to ensure better coverage.

Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
- Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
- Placement is often random and scattered as diseases are spread through raindrops.
- May appear on lower leaves and the interior of the plant where humidity is higher.
- Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
- Leaf margins may turn yellow.
- Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
- Blotches grow in size until the entire leaf is brown.
- The leaf falls off the plant.
Severe Symptoms
- Partial or complete premature defoliation
- Reduced growth
- Increased susceptibility to pests and other diseases
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
- Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
- Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
- Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
- Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
- Maintain good air movement between plants through proper plant spacing.
- Increase air circulation through the center of plants through pruning.
- Thoroughly clean all pruning tools after working with diseased plants.
- Never dispose of disease plant material in a compost pile.
- Avoid overhead watering to keep moisture off of the foliage.
- Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
For less serious cases:
- Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
- Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
- Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
To prevent infestations of leaf beetles, follow these practices.
- Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
- Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
- Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
- Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Overview
Black spot is a fungus that largely attacks leaves on a variety of ornamental plants, leaving them covered in dark spots ringed with yellow, and eventually killing them. The fungus is often simply unsightly, but if it infects the whole plant it can interfere with photosynthesis by killing too many leaves. Because of this, it is important to be aware of the best methods for preventing and treating this diseases should it occur in the garden.
Symptom Analysis
Here are a few of the most common symptoms of black spot:
- The plant has developed small black spots along the leaves.
- These spots be small, circular, and clustered together, or they may have a splotchy appearance and take up large portions of the leaves.
- The fungus may also affect plant canes, where lesions start purple and then turn black.
- The plant may suffer premature leaf drop.
Though most forms of black spot fungus pose little risk to a plant's overall health, many gardeners find them unsightly. Severe cases can also weaken a plant, so it becomes more susceptible to other pathogens and diseases.
Disease Cause
Black spot is spread by various types of fungi, which differ slightly depending on whether they are in their sexual or asexual stages.
The fungal spores linger over the winter in fallen leaves and lesions on canes. In the spring, the spores are splashed up onto the leaves, causing infection within seven hours of moisture and when temperatures range between 24 to 29 ℃ with a high relative humidity.
In just two weeks, thousands of additional spores are produced, making it easy for the disease to infect nearby healthy plants as well.
There are several factors that could make a plant more likely to suffer a black spot infection. Here are some of the most common:
- Exposure to infected plants or mulch (the fungus overwinters on dead leaves)
- Weakening from physical damage, pest infestation or other infections.
- Increased periods of wet, humid, warm weather – or exposure to overhead watering
- Plants growing too close together
Solutions
Some steps to take to address black spot include:
- Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves.
- Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash.
- Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil.
- Use a spreader in the fungicide spray to ensure better coverage.
Prevention
Here are a few tips to prevent black spot outbreaks.
- Purchase resistant varieties: Invest in fungus-resistant plant varieties to reduce the chances for black spot diseases.
- Remove infected plant debris: Fungi can overwinter in contaminated plant debris, so remove all fallen leaves from infected plants as soon as possible.
- Rake and discard fallen leaves in the fall.
- Prune regularly.
- Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback. Adding a layer of mulch to the soil will also reduce splashing.
- Grow plants in an open, sunny locations so the foliage dries quickly.
- Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation.
- Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.

Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
- Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
- Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
- Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
- Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
- Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
- Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
- Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Plan your green oasis based on your criteria: plant type, pet safety, skill level, sites, and more.
Common Problems
Why is my damask rose not blooming?
Damask rose needs enough sunlight and nutrients to bloom. Without sufficient light, it seldom grows flower buds. If it has buds but does not bloom normally, it is usually due to a lack of nutrients. Granular fertilizer and foliar fertilizer can be used at the same time to rectify this. Smaller buds on the same branch can also be removed, leaving only 1-2 of the largest buds so as to concentrate nutrition and avoid excessive nutrient consumption. Additionally, some varieties only bloom in spring, while others also bloom in fall and even in summer. Therefore, it is necessary to pay attention to the varieties you planted.
Why do my damask rose leaves turn yellow?
Yellow leaves can have many causes. It may be a natural phenomenon, in which case there is no need to worry. Or, it may be due to improper fertilization like excessive fertilizer concentration. This requires a lot of water to irrigate and wash the flower soil or may require replacing it with new soil to alleviate the problem. Yellowing may also be due to excessive rainfall, too much soil moisture, or root system damage, for which you can slightly loosen the soil to accelerate water loss. There may also be too much sunlight, which burns the leaves. In this case, you need to cut off the burned yellow leaves first, then provide proper shade for the plant. For example, you can move a potted rose to a shady corner, or set up a shading net for roses planted in the garden.
