Powdery mildew can really destroy how your plants look, and can eventually decay and kill your plants too. You can prevent powdery mildew from attacking your plants by changing the environment so that mildew can’t thrive. Let’s look at the causes of powdery mildew:
The Causes of Powdery Mildew
Powdery mildew is a white or gray powder that cover the leaves, stems, flowers or fruit of plants. It starts in patches and slowly spreads out to cover both sides of the plant. Before you see patches, the leaves may begin to curl and twist. After the plant has been covered in the patches the leaves will turn yellow, then brown and will eventually fall off completely. Young plants are particularly susceptible to powdery mildew.
Powdery mildew typically affects plants when the temperature is between 60 and 80 degrees. Because of this, powdery mildew is most common in the spring and fall when temperatures are more moderate.
Most mildew and mold spores need freestanding water to grow. Powdery mildew, however, doesn’t necessarily need freestanding water, but it does require excess moisture. Therefore, areas with high humidity typically have more cases of powdery mildew.
The causes of powdery mildew are varied, but prevention is simple. You can prevent powdery mildew by making sure there’s plenty of air circulation between plants. This will encourage evaporation and lower humidity. You can accomplish this by spacing the plants further apart or to plant them so that they get at least a few hours of sunlight every day.
If your plants already suffer from powdery mildew, you should consider using Pure 3-Way, an all-natural fungicide, to aid in the treatment. Pure 3-Way contains natural ingredients, like lemon grass oil, that help to promote plant health while simultaneously keeping the environment and your loved ones safe.
