What Is the Cause of Brown Leaves on a Rose Bush?


Brown leaves on rose bushes can be caused by fungal infections in humid areas. Fungal infections occur when the leaves stay damp and don’t have enough sunlight to dry out. Roses should be kept pruned and watered under the plant at the soil line instead of overhead.

Roses are a favorite of gardeners because of their beautiful colors and hardiness. They come in a variety of shapes and sizes and should be chosen with the size of the garden and amount of sunlight per day in mind. Rose bush leaves must be kept dry, and the bushes will blooms for years.
