To use it, mix 1 tablespoon of horticultural oil with 1 gallon of water and spray it on the affected leaves, being sure to coat both the top and bottom surfaces. Apply the oil once a week until the powdery mildew is gone.
4. Destroy infected leaves
Powdery mildew can be controlled by destroying the infected leaves. To do this, use a sharp knife or scissors to cut the leaf off at the stem. Be sure to disinfect the knife or scissors between cuts with a bleach solution (1 part bleach to 9 parts water), and wear gloves to protect your hands. Discard the infected leaves in the trash.
The dangers of powdery mildew and the effects it can have on your plants
Powdery mildew is a type of fungal disease that can affect a wide range of plants, including hydrangeas. The telltale signs of powdery mildew are white or grayish-white powdery patches on the leaves and stems of infected plants. Powdery mildew is caused by a group of fungi called Erysiphales, which thrive in warm, humid conditions.
Powdery mildew can cause serious damage to your plants if left untreated. Serious damages include:
Stunted growth of buds and leaves
Powdery mildew can cause significant damage to your plants, including stunted growth of buds and leaves. If left untreated, powdery mildew can cause serious damage to your plants, including death. There are a number of ways to treat powdery mildew, including using fungicides or organic controls.
Leaf distortion is a common symptom of powdery mildew. Leaves affected by powdery mildew may appear twisted, curled, or otherwise distorted.
Reduced plant vigor
Plants infected with powdery mildew often show reduced plant vigor, as the fungus saps the plant of its energy.
Yellowing or discoloration of leaves
Many plants infected with powdery mildew also show symptoms of yellowing or discoloration of leaves. This is a result of the fungus destroying the chlorophyll in the leaves, which causes them to lose their green color. While not all cases of yellowing or discoloration are caused by powdery mildew, it is one of the most common reasons for these symptoms.
Premature leaf drop
Premature leaf drop is a common symptom of powdery mildew. Leaves affected by powdery mildew may appear twisted, curled, or otherwise distorted. Premature leaf drop can cause a plant to lose its leaves prematurely, which can reduce its overall vigor and health.
Reduced flower production
Powdery mildew can also cause reduced flower production in infected plants. This is because the fungus interferes with the plant’s ability to produce flowers.
Prevention tips for keeping powdery mildew from coming back
Powdery mildew is more likely to return if the environment is favorable for its growth. The pathogen that causes powdery mildew thrives in warm, humid conditions.
Spores can survive from one season to the next on infected plant debris, so it’s important to remove and destroy any affected leaves, stems, or flowers in the fall.
Powdery mildew can also overwinter in infected plant tissue, so it’s important to prune out any diseased areas in the spring.
The following cultural practices can help reduce the risk of powdery mildew:
- Plant powdery mildew-resistant varieties.
- Space plants properly to promote good air circulation.
- Avoid overhead watering. Water plants at the base, using soaker hoses or drip irrigation.
- Remove and destroy infected plant parts as soon as you see them.
- Apply a fungicide according to label instructions if powdery mildew is a problem in your garden. Be sure to select a fungicide that is specifically labeled for use on powdery mildew.

How Powdery Mildew Gets on Hydrangeas?
Fungal diseases like powdery mildew love warm, humid weather. The fungus overwinters on fallen leaves, plant debris, and even your gardening tools. In the spring, the spores blow in the wind and land on hydrangea leaves.
If conditions are right, the spores germinate and send out rootlike structures called haustoria that penetrate the leaf surface. The fungus then begins to grow and reproduce.
Powdery mildew doesn’t usually kill hydrangeas, but it can weaken them and make them more susceptible to other problems, such as leaf spots. Powdery mildew also decreases the plant’s aesthetic value.
What Does Powdery Mildew Look Like?
Powdery mildew looks like, well, powder. It’s a white or grayish-white powder that covers the leaves, stems, and sometimes even the flowers of infected plants.
If you look closely at a leaf with powdery mildew, you’ll see that the powder is made up of thousands of tiny spores. These spores are produced by the fungus and are released into the air to start new infections.
When powdery mildew first appears, it usually looks like white or grayish-white specks on the leaves. These specks soon spread and cover the entire leaf surface with a powdery film. The undersides of the leaves may also be affected.
As the disease progresses, the leaves may turn yellow or brown and curl up. Severely infected leaves may drop off the plant.
I know how disheartening it can be to see a fungal infection like powdery mildew taking over your beloved hydrangeas. But don’t despair! There are several things you can do to prevent and treat this problem.
Start by making sure your plants are healthy and well-nourished. Then, try to create a more humid environment around your plants. And finally, use preventative treatments against powdery mildew.
With a little care and attention, you can keep powdery mildew from ruining your hydrangeas.
