Fungal Issues
Posted by TON Staff on Aug 7th 2024
Why are my plants having fungal issues?
Fungal issues are typically a response to a combination of environmental factors. Too much rain combined with warm day time temperatures and high humidity. This trifecta hitting at the same time creates and environment for fungus to thrive. Below are a couple of common fungus problems we see and how to treat them.
Powdery Mildew
Is one of the most widespread and easily identifiable plant fungal diseases; it looks just like its name. The mildew forms a white or gray powdery film on a plant's leaves, stems and fruit. From vegetables to roses, ornamental trees and shrubs, almost no type of plant is immune.

Preventative and first sight fungal control
- Clean up and dispose of fallen leaves and debris surrounding plants.
- Prune infected plant parts and dispose of them properly.
- Provide plants with adequate nutrients and water to maintain their immune defenses.
- Keep the soil well watered and mulched to prevent moisture loss and to cover up overwintering spores.
- Space plants far enough apart to provide good air circulation and prune them regularly to prevent overcrowding.
- Use fans to provide adequate ventilation during humid nights.
- Water the roses in mid-morning so the foliage can dry rapidly and to avoid infection by other fungal pathogens.
- Use fungicides as a preventive measure during optimal growth conditions. Be sure to read the product labels and follow all directions.
