Have you ever noticed white or gray powdery spots on the leaves of some plants in your garden? It might look like your plant has some horrible disease and will need to be removed, but thankfully the nearly universal problem with powdery mildew isn’t all that harmful if you catch and treat it early on. In fact, the best way to treat this plant fungal disease is prevention, but that isn’t always possible. With that in mind, here are a few ways to get rid of powdery mildew in your garden.
Powdery mildew is a fungal disease, so like most mildew it thrives in moist climates. If your plants’ leaves are dry, maybe because of a week of 90-degree plus days, they are more susceptible to developing this problem. Another major cause is installing plants too close together. This leads to plants that don’t get enough air or light to help fight off powdery mildew.
Like the old saying goes, “The best offense is a good defense.” Some plants are simply less likely to get powdery mildew than others. If you’re worried about the disease try planting varieties of plants that are more naturally resistant. Fight the common causes of powdery mildew by giving your plants enough space to get adequate air and light.
If you do notice an infection, try using an over the counter fungicide. These products usually work well, but many leave a milky white film on the leaf surface that doesn’t look great. One great, homemade solution is to mix baking soda with horticultural grade liquid soap and apply it during the early stages of an outbreak. If you need more help controlling powdery mildew, head over to your local garden center and ask a professional!
