White Fuzz On Tree Leaves – Have you seen white spots on your leaves? Are your leaves dusted with powdery round patches?
If so, you’re most likely dealing with white powdery mold, or white powdery mold, also known as “WPM” to cannabis growers.
White Fuzz On Tree Leaves
White powdery mildew is usually a minor nuisance that can be easily remedied, but if you don’t catch it early, WPM can be a disaster that wipes out an entire marijuana crop!
How To Get Rid Of White Fuzzy Fungus On Plants (powdery Mildew)
For those who haven’t experienced WPM, imagine circular patches of a living, breathing, fuzzy, mealy substance appearing on your plant’s leaves without warning. From there, the fungus easily spreads to other leaves and buds, rendering the buds unusable.
White powdery mildew has an easy time spreading, and even careful growers who take proper precautions can experience it.
Fortunately, the problem pictured above was easily solved because it was caught early and the white powder was completely reversible up to a point.
This article will give you information on how to prevent the spread of WPM.

White powdery mildew is a fast-reproducing fungus (sexually and asexually) known to do only two things:
Fortunately, white mold is easy to spot because it produces white spots on fungal growths that stand on the green leaves of a cannabis plant.
If it is detected early, it can be removed from the plants with proper treatment, but any buds with WPM should be discarded, as they often contain too many spores to be seen by the eye.
It was a struggle if I noticed it later or waited to fix the problem. That’s the good thing about WPM: In most cases, if WPM is caught early enough, you can remove all traces of mold without damaging your plants.
Controlling Citrus Sooty Mold
There are many products and home-made mixtures that people use to treat WPM. Among the effective treatments are:
Here’s a simple trick I use to get rid of whiteheads on the first try every time! Here’s my trusted 3-step white powder treatment:
Here it is! If you run into white powdery mildew, give this advice a shot and you won’t have to deal with that first day. If you use these steps, let us know if it helped you or how you did it differently. If farmers know a little about this plant disease, it doesn’t stand a chance!

Milk – Mix 1 part milk with 3 parts water and spray liberally when your grow lights are on. The type of milk (skimmed, 2%, whole, etc.) doesn’t matter. Moisten both sides of the leaves if possible.
Potassium Bicarbonate – Dissolve 1 teaspoon of potassium bicarbonate in 1 gallon of water. Optional: Add 1 teaspoon of vegetable oil and 3 drops of liquid soap. Spray the plants lightly but evenly. Do this when the lights are off.
Baking soda (not as effective as milk or potassium bicarbonate) – Mix 1 teaspoon of baking soda, 1 teaspoon of liquid soap, and 1 gallon of water. Spray all leaves top and bottom.

But sometimes, whether you’re a novice or a pro, you’ll run into problems with terrain. Powdery mildew on plants—a white fuzz or powder that usually appears on leaves and sometimes stems, flowers, or fruit—is a common disease. “A white-gray mildew develops on the upper leaf surface and is relatively easy to brush off with your finger,” says Paul Horticultural Institute Horticulturist Sam Schmitz. If they surface, the whole plant can be affected.
“Pine powdery mildew is actually an umbrella term for fungi that cause similar symptoms, like a vague powdery mildew on leaves,” says horticulturist Jesse Liebenguth of Riemann Canes at Iowa State University. Because there are many fungi that cause powdery mildew, almost all plants can be affected.”
But don’t worry too much about white mold on plants or finding white mold balls in the soil. If caught early, these fungal diseases are easy to stop. As with other growing issues—like what it means to see brown tips on leaves or how to revive a dead plant—there are tips and tricks that will make sure everyone has a healthy green thumb. Of course, sometimes knowing what conditions your indoor plants need means choosing low-light houseplants or hay-to-kill houseplants.
How To Get Rid Of White Wax Scale
Powdery mildew is a fungal disease that goes unnoticed until the environment is right. “Spores that cause powdery mildew are present even when the plant isn’t showing symptoms,” explains Bloomscape expert Lindsay Pangborn. “When the conditions are right, they start showing up.” Wind, water, and even insects can carry spores.
What is the best environment for white mold to grow on plants? “Shade, poor air circulation, high humidity and moderate temperatures are favorable conditions for powdery mildew growth,” explains Lipengath.
In an ideal environment, the white powder on the plants blooms quickly. “Yes powdery mildew thrives in areas with poor air movement in the moderate temperature range, with high humidity in the evenings and relatively dry days, typically between 60 and 85 degrees,” Schmitz says.
Although all plants can develop powdery mildew, some are more susceptible than others. And there are plant varieties bred to resist powdery mildew. While you can certainly buy plants online, it’s worth shopping around at a local garden center or nursery to inquire about the plant’s risks. The list below will give you a good idea of which plants are susceptible to fungal disease.
What You Can Do About That Mysterious White Stuff On Your Plants
Powdery mildew is obvious when it begins to appear on the leaves – it looks like white dust or white powder. “Powder powdery mildew is usually seen over a wide area of the plant, as small, white, circular spots or discoloration on the plant’s leaves,” explains Pangborn.
As it spreads, you will notice changes in the plant. “In its most advanced stages, it will completely cover the leaf in white or gray, and the leaf itself will begin to turn brown,” says Pangborn.
As soon as powdery mildew is found on plants, take steps to prevent the growth of the fungus. If not, disease will attack and alter the leaves’ ability to absorb sunlight. “When the leaf surface is shaded it hurts the plants and prevents them from photosynthesizing,” says Schmitz. “These leaves can start to become a drain on the plant’s resources rather than contributing to the plant’s overall health.”
Powdery mildew can spread to the same or different varieties of a plant. So if there are many zucchini plants growing in the garden and one of them has downy mildew, it is more likely that the other zucchini plants will be affected in a short period of time.

If you have other plants—flowers or vegetables like beans, for example—growing nearby, the fungus won’t spread through them. “Because powdery mildew can’t spread between different plants, it won’t take over your entire crop unless you have a monoculture,” says Lipengath.
There are several ways to reduce and eliminate powdery mildew on plants. The sooner you spot the white powder and take action, the easier it will be to control. “The sooner the infection is treated, the better the chance of recovery,” says Pangborn.
Spotting white spot on plants is like spotting mold in houseplant soil – knowing what to do can make these problems much easier. Once you notice powdery mildew on your plants, take the steps below.
“A good first step is to trim dead leaves and stems and remove them immediately to prevent further spread of spores,” says Pangborn. This will improve ventilation, although additional steps must be taken to increase ventilation.
Indoor Powdery Mildew Control
Keep this tip from Pangborn in mind when you’re pruning: Sterilize your tools to avoid spreading spores to other plants.
Schmitz offers this engineering tip: Once you’ve given the plants plenty of air, wash the surface of the leaves with a mixture of water and mild soap to remove as much of the pathogen as you can.
You’d think that chemical-based methods would eliminate powdery mildew on plants, but they’re more of a prevention than a cure. “Most fungicides are preventative rather than curative, so when symptoms of powdery mildew appear, it may not be effective.
