What's the best method to water my Common ninebark?
You might want to put a garden hose at the plant base to ensure that you're promoting excellent root development. Avoid directly spraying the leaves, and know that the leaves will require more watering if they are outdoors and facing direct sunlight. You can also use bubblers that you can put on to each plant to moisten the roots. Also, use soaker hoses that can cover the entire garden or bed when adding or removing plants to push the roots deeply. Drain any excess water and wait for the soil to dry before watering. Water at ground level to prevent diseases. On a sunny day, you might want to spray the entire bush with water. Whether potted or in-ground, please remember Common ninebark prefers deep watering over light sprinkling.

What should I do if I water Common ninebark too much/too little?
An overwatered Common ninebark can start to have leaves that turn yellow, drop off and wilt. The plant can also look dull and unhealthy, with signs of mushy stems. When they are beginning to show these signs, it's best to adjust your schedule whenever possible. The wilting can also be a sign of under watering as well. You might see that the leaves begin to turn crispy and dry while the overwatered ones will have soft wilted leaves. Check the soil when it is dry and watering is not enough, give it a full watering in time. Enough water will make the Common ninebark recover again, but the plant will still appear dry and yellow leaves after a few days due to the damaged root system. Once it return to normal, the leave yellowing will stop . Always check the moisture levels at the pot when you have the Common ninebark indoors. Avoid overwatering indoors and see if there are signs of black spots. If these are present, let the soil dry in the pot by giving it a few days of rest from watering. Overwatering can lead to root rot being present in your plant. If this is the case, you might want to transfer them into a different pot, especially if you see discolored and slimy roots. Always prevent root rot as much as possible, and don't let the soil become too soggy. You should dig a little deeper when you plant your Common ninebark outdoors. When you check with your fingers and notice that the soil is too dry, it could mean underwatering. Adequate watering is required to help the plant recover.

How often should I water my Common ninebark?
The Common ninebark likes deep and infrequent watering. You would want to soak them in a gallon of water each time, especially when they are planted in pots. The water storage of flower pots is limited and the soil will dry out faster. Watering is required every 3 to 5 days when living in a cold region. Water it early in the morning when the soil is dry, outdoors or indoors. You can also determine if watering is needed by checking the soil inside. When the top 2-3 inches of soil is dry, it is time to give the plant a full watering. During hot days, you may need to check the moisture daily, as the heat can quickly dry out the soil in the pot. Irrigation of the soil is also required if you have a garden. When you live in a hot climate, you might want to water once a week. Only water when you notice that about 2 to 3 inches of soil become too dry outdoors or indoors. Consider the amount of rainwater on the plant and ensure not to add to it to prevent root rot.You may not need additional watering of the plants if there is a lot of rainfall.Common ninebark generally grows during spring and fall. When they are outdoors, you need to add mulch about 3 to 4 inches deep to conserve more water. You need to water the plants more frequently in sandy soil because this type tends to drain faster. However, with the clay one, you need to water this less frequently where you could go for 2-3 days to dry the plant and not develop any root rot. You could mark the date on the calendar whenever you water and when you notice that the leaves are starting to droop. This can mean that you might be a day late.

How much water do I need to give my Common ninebark?
The Common ninebark generally needs about a gallon of water each schedule,With the potted plants, you might want to water them deeply until you see that the water is dripping at the bottom of the pot. Then, wait for the soil to dry before watering them again. You can use a water calculator or a moisture meter to determine the amount you've given to your plant in a week. Provide plenty of water, especially in the flowering period, but let the moisture evaporate afterwards to prevent root rot. If Common ninebark is planted outdoor with adequate rainfall, it may not need additional watering. When Common ninebark is young or newly planted, make sure it gets 1-2 inches of rain per week. As Common ninebark continues to grow, it can survive entirely on rainfall. Only when the weather is too hot, or when there is no rainfall at all for 2-3 weeks, then consider giving Common ninebark a full watering during the cooler moment of the day to prevent the plant from suffering from high heat damage. Additional watering will be required during persistent dry spells.

Should I adjust the watering frequency for my Common ninebark according to different seasons or climates?
The Common ninebark needs outdoors come from rain, with only persistent dry weather requiring watering. Throughout the spring and fall growing seasons, the soil needs to be kept moist but not soggy, and alternating dry and moist soil conditions will allow the Common ninebark to grow well. Throughout the summer, hot weather can cause water to evaporate too quickly, and if there is a lack of rainfall, you will need to water more frequently and extra to keep it moist. Usually, the Common ninebark will need less water during the winter. Since the Common ninebark will drop their leaves and go dormant, you can put them into a well-draining but moisture-retentive soil mixture like the terracotta to help the water evaporate quicker. Once your Common ninebark growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Common ninebark can rely on the fall and winter rains to survive the entire dormant period. After the spring, you can cultivate your Common ninebark and encourage it to grow and bloom when the temperature becomes warmer.This plant is not generally a fan of ponding or drought when flowering. You must ensure that the drainage is good at all times, especially during the winter. When the plant is in a pot, the plant has limited root growth. Keep them well-watered, especially if they are planted in pots during summer. They don't like cold and wet roots, so provide adequate drainage, especially if they are still growing. It's always best to water your Common ninebark’s diligently. Get the entire root system into a deep soak at least once or twice a week, depending on the weather. It's best to avoid shallow sprinkles that reach the leaves since they generally encourage the growth of fungi and don't reach deep into the roots. Don't allow the Common ninebark’s to dry out completely in the fall or winter, even if they are already dormancy. Don't drown the plants because they generally don't like sitting in water for too long. They can die during winter if the soil does not drain well. Also, apply mulch whenever possible to reduce stress, conserve water, and encourage healthy blooms.

What should I be careful with when I water my Common ninebark in different seasons, climates, or during different growing periods?
If planting in the ground, Common ninebark mostly relies on rain. However, if there is no rainfall for 2-3 weeks, you may need to give proper consideration to giving the plants a deep watering. If watering Common ninebark in summer, you should try to do it in the morning. A large temperature difference between the water temperature and the root system can stress the roots. You need to avoid watering the bushes when it's too hot outside. Start mulching them during the spring when the ground is not too cold. The age of the plants matter. Lack of water is one of the most common reasons the newly planted ones fail to grow. After they are established, you need to ease off the watering schedule. Reduce watering them during the fall and winter, especially if they have a water-retaining material in the soil. The dry winds in winter can dry them out, and the newly planted ones can be at risk of drought during windy winter, summer, and fall. Windy seasons mean that there's more watering required. The ones planted in the pot tend to dry out faster, so they need more watering. Once you see that they bloom less, the leaves begin to dry up. Potted plants are relatively complex to water and fluctuate in frequency. Always be careful that the pot-planted plant don't sit in the water. Avoid putting them in containers with saucers, bowls, and trays. Too much watering in the fall can make the foliage look mottled or yellowish. It's always a good idea to prevent overwatering them regardless of the current climate or season that you might have. During the months when Common ninebark begins to flower, you might want to increase the watering frequency but give it a rest once they are fully grown. Give them an adequate amount of water once every 3 to 5 days but don't give them regular schedules. Make sure the soil is dry by sticking your finger in the pot, or use a moisture meter if you're unsure if it's the right time. Too much root rot can cause them to die, so be careful not to overwater or underwater regardless of the climate or season you have in your area.

Why is watering my Common ninebark important?
Watering the Common ninebark helps transport the needed nutrients from the soil to the rest of the plant. The moisture will keep this species healthy if you know how much water to give. The watering requirements will depend on the weather in your area and the plant's soil. The Common ninebark thrives on moist soil, but they can't generally tolerate waterlogging. Ensure to provide enough mulch when planted on the ground and never fall into the trap of watering too little. They enjoy a full can of watering where the water should be moist at the base when they are planted in a pot to get the best blooms. If they are grown as foliage, you need to water them up to a depth of 10 to 20 inches so they will continue to grow. If it's raining, refrain from watering and let them get the nutrients they need from the rainwater.

Common issues for Common ninebark based on 10 million real cases
Flower withering
Flower withering is a disease affecting Common ninebark, causing its flowers to lose vitality, eventually leading to their premature decay and overall detriment of the plant. This disease impacts both the physical appearance and the overall health of Common ninebark.
Brown spot
Brown spot Brown spot
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.
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.
Powdery Mildew
Powdery Mildew Powdery Mildew
Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Solutions: As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms: If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure. In cases where powdery Mildew is more widespread, plants can be sprayed with a mild sulfur- or copper-based fungicide or a non-toxic solution made from baking soda and soap. Sprays can help areas that have been recently infected, though they are less effective against well-established infections. If possible, try transplanting the plants to a sunnier location. Though powdery Mildew does fine in hot, dry conditions, it is unable to reproduce without some humidity. Putting plants in more direct sunlight can help stop the spread of the fungus. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.
Yellow spot
Yellow spot Yellow spot
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
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
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
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.

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.

Powdery Mildew
plant poor
Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Overview
Overview
Powdery Mildew is a common disease and the scourge of many home gardeners. It affects a large variety of plants including many varieties of vegetables. The disease is easy to identify but not always easy to get rid of once it has started to infect plants.
Powdery Mildew thrives in warm, humid conditions and can quickly spread from plant to plant. Although this disease will not kill the plants, a severe infestation will inhibit plant growth and fruit production.
Symptom Analysis
Symptom Analysis
Powdery Mildew appears as pale yellow spots on leaves. These spots then become white and look powdery. The fungus spreads quickly both on the top and underside of the leaves and on the plant stems.
These white, powdery spots will join up and soon, almost the entire surface of the leaf appears white. Eventually, the edges of the leaf will turn brown and dry and start to die.
In severe infections, even the flower buds will turn white and become disfigured. Fruit will ripen prematurely and be inedible.
Disease Cause
Disease Cause
Powdery Mildew is caused by a fungus. There are many different genera of fungus diseases that cause powdery Mildew. The fungal spores overwinter inside leaf buds and on plant material that has dropped to the soil below. As the weather warms up, these spores are then carried onto the plant by water, wind, and insects. Powdery Mildew can also be more severe in areas that experience warm, dry climates, even though the spores require some humidity to germinate.

Yellow spot
plant poor
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Overview
Overview
Yellow spot is a common condition that affects all types of plants -- flowering ornamentals, trees, shrubs, herbs, and vegetable plants -- worldwide. Yellow spots may appear because of dozens of potential causes and occur in various environmental and climatic conditions, but fortunately, most are easy to address. The most common causes of yellow spots include diseases, nutrient deficiency, watering problems, and pests.
In most cases, yellow spots can be treated without permanent damage to the plant. However, in some fungal disease cases, nothing can be done to treat the disease after infection, and the plant will ultimately perish from the disease.
Due to this, the most critical aspect of addressing yellow spots on plants is correctly determining the cause.
Symptom Analysis
Symptom Analysis
Symptoms occur on varying parts of the plant, depending upon the cause. Smaller spots tend to be indicative of younger infections or newly developing problems.
  • Small yellow spots appear on leaves
  • Spots can occur on the lower or upper leaf surfaces, or both
  • Raised, rounded, or sunken spots with fringed or smooth edges
  • Spots may grow together, causing leaves to become totally discolored
  • Stunted growth
  • Premature leaf drop
Disease Cause
Disease Cause
The vast majority of yellow spot diseases are caused by fungal pathogens. However, there are some situations in which bacteria, environmental conditions, or other issues may be blamed.
Diseases are typically host-specific, so they may only affect plants within the same family. That said, just about every single species of plant is vulnerable to at least one disease that causes yellow spot. The most common problems are leaf blight, leaf septoria, powdery mildew, and downy mildew, to name a few.
All plants need specific nutrients from the soil to survive. When these nutrients become depleted or unavailable for plant uptake due to particular conditions, deficiencies occur, and yellow spots are seen.
  • Nitrogen is an integral component of chlorophyll.
  • Iron is needed in the enzymes that make chlorophyll.
Yellow spots may also appear because of incorrect watering, mainly underwatering, or infestations of sap-sucking pests such as aphids.
  • Too little water inhibits photosynthesis. Too much water pushes oxygen out of the soil and the roots cannot take in nutrients or even water from the soil.
  • Insect problems can cause yellow spots directly by damaging leaf tissue when feeding, or they may introduce pathogens.

Brown spot
Brown spot Brown spot 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.

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.

Powdery Mildew
Powdery Mildew Powdery Mildew Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Solutions: As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms: If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure. In cases where powdery Mildew is more widespread, plants can be sprayed with a mild sulfur- or copper-based fungicide or a non-toxic solution made from baking soda and soap. Sprays can help areas that have been recently infected, though they are less effective against well-established infections. If possible, try transplanting the plants to a sunnier location. Though powdery Mildew does fine in hot, dry conditions, it is unable to reproduce without some humidity. Putting plants in more direct sunlight can help stop the spread of the fungus. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.

Yellow spot
Yellow spot Yellow spot Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
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
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
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
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.
  1. 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.
  2. 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.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
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.

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.
Solutions
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.
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.

Powdery Mildew
plant poor
Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Overview
Overview
Powdery Mildew is a common disease and the scourge of many home gardeners. It affects a large variety of plants including many varieties of vegetables. The disease is easy to identify but not always easy to get rid of once it has started to infect plants.
Powdery Mildew thrives in warm, humid conditions and can quickly spread from plant to plant. Although this disease will not kill the plants, a severe infestation will inhibit plant growth and fruit production.
Symptom Analysis
Symptom Analysis
Powdery Mildew appears as pale yellow spots on leaves. These spots then become white and look powdery. The fungus spreads quickly both on the top and underside of the leaves and on the plant stems.
These white, powdery spots will join up and soon, almost the entire surface of the leaf appears white. Eventually, the edges of the leaf will turn brown and dry and start to die.
In severe infections, even the flower buds will turn white and become disfigured. Fruit will ripen prematurely and be inedible.
Disease Cause
Disease Cause
Powdery Mildew is caused by a fungus. There are many different genera of fungus diseases that cause powdery Mildew. The fungal spores overwinter inside leaf buds and on plant material that has dropped to the soil below. As the weather warms up, these spores are then carried onto the plant by water, wind, and insects. Powdery Mildew can also be more severe in areas that experience warm, dry climates, even though the spores require some humidity to germinate.
Solutions
Solutions
As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms:
  1. If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this.
  2. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection.
  3. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure.

  6. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.
Prevention
Prevention
There are a few ways to prevent a powdery Mildew infection from occurring in the first place:
  1. Preemptive chemical controls, including fungicides and non-toxic solutions, can help prevent powdery Mildew from becoming established on plants.
  2. When placing new plants, allow enough space between each one to provide adequate air circulation.
  3. Water at the base of plants rather than from overhead.
  4. Many mildew-resistant strains of common garden plants are available. Consider these in areas that have a Mediterranean climate.
  5. Powdery Mildew can form tiny, round black structures, called cleistothecia, as the growing season draws to a close. These hardy, dry structures help the fungus survive winter. Raking away debris over the winter can remove stowaway cleistothecia and will help prevent plants from being reinfected.

Yellow spot
plant poor
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Overview
Overview
Yellow spot is a common condition that affects all types of plants -- flowering ornamentals, trees, shrubs, herbs, and vegetable plants -- worldwide. Yellow spots may appear because of dozens of potential causes and occur in various environmental and climatic conditions, but fortunately, most are easy to address. The most common causes of yellow spots include diseases, nutrient deficiency, watering problems, and pests.
In most cases, yellow spots can be treated without permanent damage to the plant. However, in some fungal disease cases, nothing can be done to treat the disease after infection, and the plant will ultimately perish from the disease.
Due to this, the most critical aspect of addressing yellow spots on plants is correctly determining the cause.
Symptom Analysis
Symptom Analysis
Symptoms occur on varying parts of the plant, depending upon the cause. Smaller spots tend to be indicative of younger infections or newly developing problems.
  • Small yellow spots appear on leaves
  • Spots can occur on the lower or upper leaf surfaces, or both
  • Raised, rounded, or sunken spots with fringed or smooth edges
  • Spots may grow together, causing leaves to become totally discolored
  • Stunted growth
  • Premature leaf drop
Disease Cause
Disease Cause
The vast majority of yellow spot diseases are caused by fungal pathogens. However, there are some situations in which bacteria, environmental conditions, or other issues may be blamed.
Diseases are typically host-specific, so they may only affect plants within the same family. That said, just about every single species of plant is vulnerable to at least one disease that causes yellow spot. The most common problems are leaf blight, leaf septoria, powdery mildew, and downy mildew, to name a few.
All plants need specific nutrients from the soil to survive. When these nutrients become depleted or unavailable for plant uptake due to particular conditions, deficiencies occur, and yellow spots are seen.
  • Nitrogen is an integral component of chlorophyll.
  • Iron is needed in the enzymes that make chlorophyll.
Yellow spots may also appear because of incorrect watering, mainly underwatering, or infestations of sap-sucking pests such as aphids.
  • Too little water inhibits photosynthesis. Too much water pushes oxygen out of the soil and the roots cannot take in nutrients or even water from the soil.
  • Insect problems can cause yellow spots directly by damaging leaf tissue when feeding, or they may introduce pathogens.
Solutions
Solutions
Diseases
Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals.
For bacterial infections, apply a spray containing copper or streptomycin.
For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best.
Nutrient deficiency
Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range.
Incorrect watering
Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered.
Pests
Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.
Prevention
Prevention
Depending on the type of plant and which specific disease is causing yellow spot, problems may be avoided by taking the following preventative steps:
  • Plant resistant varieties
  • Avoid planting susceptible varieties close together - space susceptible plants further apart from one another so it’s more difficult for the fungal spores to find new plant hosts.
  • Water wisely - water from below rather than splashing water on foliage. This can reduce the spread of both bacterial and fungal pathogens responsible for yellow spot.
  • Prune - prune as a way of getting rid of affected leaves but also to control the spread of yellow spot to new plants. Pruning can also improve air circulation to limit disease spread.
  • Rotate crops - many diseases, including downy mildew, can live in the soil over the winter and produce problems for many years. Rotate annual crops to new locations each year so that they aren’t growing anywhere in which plants in the same family were grown within the last three to four years.
