Pruning Pruning Pruning
How can I prune my Rose pincushion cactus?
Pruning your Rose pincushion cactus is a fairly simple process. First, you will need a reliable set of hand pruners or hedge trimmers. You may use a clean pair of sharp scissors if you don’t have pruners or garden shears on hand. It’s important to always clean your gardening tools before and after using them to prevent the possibility of spreading disease or infection to other plants. To prune your Rose pincushion cactus simply allow your plant to go dormant over the Winter. Some time between late winter and early spring – or when new growth starts to appear – take your clean pruners or trimmers and cut away any dying, damaged, yellow or declining foliage. Repeat this process until you reach the base of the plant or until there are no dead pieces left to cut. When pruning, be careful not to damage the new growth that may be emerging near the base of your plant. These parts cannot be restored and pruning can increase the ventilation of the plants and facilitate their growth. Any pruning that is done to this plant should be cut straight across the blades or stems. No angled cuts are required. Diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Rose pincushion cactus is growing.

What should I do after pruning my Rose pincushion cactus?
Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives Rose pincushion cactus a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. Do not water the Rose pincushion cactus immediately after pruning as this can lead to fungal infestation of the plants through the wounds. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new growth.

How can I prune my Rose pincushion cactus during different seasons?
Early spring and late winter are the best times to prune your Rose pincushion cactus on a large scale. If you want to control the size of your Rose pincushion cactus, you can prune them as you wish, but be careful not to prune more than a third of the size of the plant. Yellow and diseased leaves may appear during the summer months when the Rose pincushion cactus is growing vigorously and these types of leaves need to be pruned back immediately. These parts of the Rose pincushion cactus cannot be restored and pruning increases the ventilation of the plant and facilitates its growth.

When should I prune my Rose pincushion cactus through different stages of growth?
Strategic pruning is usually done at different times of the year or during certain stages of growth depending on the plant. However, knowing when to prune your Rose pincushion cactus depends on where you live and how established your plant is. For example, if your Rose pincushion cactus is a new resident, it’s a good idea to wait until the plant starts to grow back before you start pruning. On the other hand, if your plant is already established, you will want to prune the dry or dead parts in plant before new leafy growth appears in early spring or late winter. This is the time of year when plants are dormant and pruning causes the least damage to them. This is also the best time of year to do more extensive pruning. It’s important to note that if Rose pincushion cactus is pruned too late in the season, it can leave new growth at risk for damage or disease. However, if your Rose pincushion cactus is indoors this is not a problem and you can prune at any time. Since this can affect the long-term health and appearance of your plant, it’s important to keep this in mind when deciding when and how to prune. As your Rose pincushion cactus grows larger over time, you can trim it as needed after annual pruning. Dead, damaged, or diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Rose pincushion cactus is growing.

Common issues for Rose pincushion cactus based on 10 million real cases
Low light
Low light Low light
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Solutions: Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed. Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn. Introduce appropriate artificial lighting. Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.
Flower withering
Flower withering Flower withering
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Fruit withering

Fungal infection or normal ripening can cause the fruit to dry out.
Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Soil mold

Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Solutions: Measures to take to remove soil mold: Physically remove mold/mushrooms - remove and dispose of mushrooms. To remove mold, scrape 1/8” of soil from the surface. Add a layer of sand or gravel - adding 1/4” of sand or gravel on top of the soil surface will discourage new fungal growth Sprinkle an antifungal treatment around the plants - this doesn't have to be a commercial fungicide, as many growers swear by all-natural remedies like cinnamon and baking soda Some types of mold contain toxins that can be harmful to humans or irritate those with allergies or asthma. Wear a dust mask while performing these tasks.

Low light
plant poor
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Overview
Overview
All plants require light, and if they do not receive it in the quantities that they require this distorts their growth in a process known as etiolation. In essence, etiolated plants are diverting all of their energy to growing taller in a desperate attempt to reach a position where they can meet their light requirements. Many other growth factors are harmed by this, and so light-deprived plants can become weak and distorted until they are almost unrecognizable. Low light symptoms are most commonly seen in houseplants, but outdoor specimens can also be affected.
Symptom Analysis
Symptom Analysis
Although symptoms will vary in different plants, the general symptoms of low light are easy to spot.
  1. Plant stems grow tall and lanky.
  2. There are less leaves, and both leaves and stems tend to be pale and insipid looking. This is due to a shortage of chlorophyll.
  3. All plant parts become weakened and may droop, as energy is diverted toward too-fast growth as the plant stretches itself toward any source of light.
Disease Cause
Disease Cause
Plants need sunlight in varying amounts for photosynthesis – a process that produces energy for growth and fruit and flower production. Low light causes a plant to divert all energy to upward (apical) growth in order to find better light. Plant hormones called auxins are transported from the actively-growing tip of the plant downwards, to suppress lateral growth. A drop in cellular pH triggers expansins, nonenzymatic cell wall proteins, to loosen cell walls and allow them to elongate. This elongation results in the abnormal lengthening of stems, especially internodes, or plant "legginess" which is observed in etoliated plants.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Fruit withering
plant poor
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
  1. Both leaves and blossom on the tips of branches will go brown and wither.
  2. Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
  3. Any fruit that does appear will turn wrinkled and fail to develop.
  4. Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.

Soil mold
plant poor
Soil mold
Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Overview
Overview
If there is soil mold around the plants, this isn't necessarily a reason to panic. Mold can occur for several reasons. Most of the time, it's harmless. The microorganisms that exist in mold are, in fact, necessary for healthy plant life. That said, it can be unsightly and in some cases, harmful to certain plants. It's important to understand why mold might be forming. It is only after the potential causes have been identified that steps can be taken to stop mold from spreading or appearing in the future.
Symptom Analysis
Symptom Analysis
The most obvious sign of soil mold is, of course, mold observed on the surface of the soil. This can be fuzzy and white, yellow, or gray in color. Other symptoms may include:
  • Mushrooms
  • Wilted plants
  • Plants are stunted in growth
  • Soil has an odd "off" smell
  • Premature leaf drop or flower/blossom/fruit rot
  • Excess water is leaking from drainage holes
While soil mold doesn't always harm the growth of a plant, it can indicate the presence of a larger problem that needs to be addressed (and these problems can often harm plants).
Disease Cause
Disease Cause
There are several causes for soil mold. Understanding why mold is growing should be the first step in deciding on the best course of action.
Some potential causes include:
  • Overwatering - fungi consume excess water, so the presence of mold indicates that there is water that the plants aren't readily using
  • Poor drainage - this can be caused by dense, compacted soil, a lack of drainage holes, or an inadequate pot size
  • Poor air circulation - this is common in indoor-grown plants, especially in the winter when windows are closed
  • Contaminated soil - while all soil contains microorganisms, soil can contain fungal spores that lead to mold growth
  • Decomposing leaves on the soil surface feed the mold

Prevention
Prevention
To avoid etiolation, provide an adequate amount of light from the beginning.
  1. Choose a location that matches each plant's ideal light needs. Many indoor plants do best in or near a south-facing window, which will provide the longest hours of sunlight. Flowering plants and those with colored leaves typically need more light than purely-green plants, as photosynthesis occurs in the green portions of leaves.
  2. Select plants with light needs that match a location's conditions. Some cultivars and varieties require less light than others.
  3. Use a grow light. Darker locations may require artificial illumination. A grow light may also become more necessary during winter, when sunlit hours are at their shortest.

In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface.
In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well.
If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Fruit withering
plant poor
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
  1. Both leaves and blossom on the tips of branches will go brown and wither.
  2. Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
  3. Any fruit that does appear will turn wrinkled and fail to develop.
  4. Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.
Solutions
Solutions
There are a number of appropriate solutions to control fruit withering:
  1. Remove any fruit as soon as it shows any signs of infection. Do not compost.
  2. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Prevention
Prevention
Preventative measures include:
  1. Ensuring adequate spacing between plants or trees.
  2. Staking plants that are prone to tumbling to prevent moisture or humidity build up.
  3. Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
  4. Practice good plant hygiene by removing fallen material and destroying it as soon as possible.

Soil mold

Soil mold
Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Overview
Overview
If there is soil mold around the plants, this isn't necessarily a reason to panic. Mold can occur for several reasons. Most of the time, it's harmless. The microorganisms that exist in mold are, in fact, necessary for healthy plant life. That said, it can be unsightly and in some cases, harmful to certain plants. It's important to understand why mold might be forming. It is only after the potential causes have been identified that steps can be taken to stop mold from spreading or appearing in the future.
Symptom Analysis
Symptom Analysis
The most obvious sign of soil mold is, of course, mold observed on the surface of the soil. This can be fuzzy and white, yellow, or gray in color. Other symptoms may include:
  • Mushrooms
  • Wilted plants
  • Plants are stunted in growth
  • Soil has an odd "off" smell
  • Premature leaf drop or flower/blossom/fruit rot
  • Excess water is leaking from drainage holes
While soil mold doesn't always harm the growth of a plant, it can indicate the presence of a larger problem that needs to be addressed (and these problems can often harm plants).
Disease Cause
Disease Cause
There are several causes for soil mold. Understanding why mold is growing should be the first step in deciding on the best course of action.
Some potential causes include:
  • Overwatering - fungi consume excess water, so the presence of mold indicates that there is water that the plants aren't readily using
  • Poor drainage - this can be caused by dense, compacted soil, a lack of drainage holes, or an inadequate pot size
  • Poor air circulation - this is common in indoor-grown plants, especially in the winter when windows are closed
  • Contaminated soil - while all soil contains microorganisms, soil can contain fungal spores that lead to mold growth
  • Decomposing leaves on the soil surface feed the mold
Solutions
Solutions
Measures to take to remove soil mold:
  • Physically remove mold/mushrooms - remove and dispose of mushrooms. To remove mold, scrape 1/8” of soil from the surface.
  • Add a layer of sand or gravel - adding 1/4” of sand or gravel on top of the soil surface will discourage new fungal growth
  • Sprinkle an antifungal treatment around the plants - this doesn't have to be a commercial fungicide, as many growers swear by all-natural remedies like cinnamon and baking soda
Some types of mold contain toxins that can be harmful to humans or irritate those with allergies or asthma. Wear a dust mask while performing these tasks.
Prevention
Prevention
Follow these practices to prevent soil mold from forming.
  • Limit moisture - avoid keeping soil damp, and allow it to dry out between waterings. Watering from the bottom of pots with drainage can allow the surface soil to stay dry.
  • Provide aeration - increase airflow around the plants using a fan or wind.
  • Repot - if the container is too small or lacks proper drainage, transplant the plant into a new, better-draining container.
  • Apply a layer of sand - apply 6 mm of sand on top of soil.
  • Use potting mix - when planting, only use potting mix instead of regular soil, as this is specially formulated for the proper moisture retention.
