It doesn’t take much for a plant to come down with a case of powdery mildew. All it needs is warmth, a little moisture, and a nice shady spot to develop and take over your plants. Powdery Mildew thrives in warm, damp, shady areas with little air circulation, but with the right mindset and a few precautions, you can easily avoid this stubborn disease.
All About Powdery Mildew
What does powdery mildew look like?
Powdery Mildew is a white spotted soft fungus, which, as you can tell by the name, has a powdery appearance. When powdery mildew begins to develop, it forms as small white circles on the leaf and then quickly reproduces, wrapping the entire leaf in a white fuzz. You’ll notice that the lower portions of your plant are more affected because those areas are more humid and sheltered. Powdery mildew forms on the both the top and bottom sides of the leaves and stem and typically occurs during summer and fall months. As the fungus enters the leafs surface, the cells remove nutrients, causing the leaves of your plant to turn yellow and eventually drop.
How does it live and grow?
Humid nights are perfect for powdery mildew. If you tend to water your plants at night, you are increasing the amount of humidity for your plants, making them more vulnerable to the disease. Once powdery mildew has attacked your plants, it’s incredibly difficult to get rid of, even impossible in many cases. However, there are some things you can do to lower or even prevent its terrible effects.
What To Do
- Always water your plants in the morning and ensure the water is distributed to the roots. If you water later in the evening, your plants will be more susceptible to becoming infected.
- Dispose of infected leaves, but don’t compost them – most home compost heaps can’t kill the powdery mildew spores.
- Promote air circulation and slow down the spread of powdery mildew by removing the worst affected leaves from your plant.
- When your plants become infected, treat them with Pure 3-Way. This fungicide stops the problem and prevents it from returning using natural ingredients, including lemongrass oil, so that your plant thrives.
Once treated, regularly apply Green Thumb to benefit your plants and prevent bugs, mold, and mildew from attacking them.
