- The symptoms of gray mold depend on the type of plant and environmental conditions, but generally spots that appear water-soaked will form on the leaves. These might appear white at first.
- These spots will then change color from gray to brown, eventually covering most of the leaf and causing it to wilt. The brown coloration is what often causes people to confuse gray mold with brown mold.
- Under really humid conditions, grayish webbing may appear on the leaves. In this webbing are structures that contain fuzzy spores. Spores become active and are released with any activity at all.
- Petals, stems, and buds can also be infected.
- Eventually, all of the infected parts of the plant will be covered by a fuzzy gray growth, causing you to seemingly become gray flowers.
