What are the common types of garden fungus that I might encounter?
The most prevalent types of garden fungus include powdery mildew, downy mildew, and gray mold. Powdery mildew appears as a white, flour-like coating on leaves and stems, often thriving in warm, dry weather while downy mildew tends to flourish in cool, moist conditions, displaying yellow spots on the upper side of leaves accompanied by a fuzzy, purple growth on the underside. Gray mold, or Botrytis, often shows up in damp and humid conditions, manifesting as a grayish-brown mold on flowers and leaves.
Less common but still concerning, fungi like rust and black spot can also affect various plants. Rust appears as rusty orange or brown spots on leaves and can lead to leaf drop, while black spot is a fungal disease primarily affecting roses, characterized by dark, circular spots on the foliage. Understanding these different types of garden fungus will help in their identification and treatment.
How can I prevent garden fungus from occurring in my garden?
Preventing garden fungus starts with good cultural practices. Ensuring adequate spacing between plants allows for better air circulation, which can help reduce humidity around the plants and decrease the likelihood of fungal outbreaks.
