Botrytis Blight - Rose Tree Botrytis Blight Fungus Disease

Botrytis Blight will cause the leaves, stems, and new growth to turn black. The buds will cause the buds to turn black and not open. One way to identify botrytis noticing a gray fuzzy growth up and down the canes. This disease usually appears during rainy cool weather. It is also triggered if plants are watered too late in the evening and allowed to be wet during cool nights. The best way to control botrytis is by getting the plants dry. Remember, roses like plenty of water, just not on their leaves, and most especially not during cool nights.
