Monthly Tip

Camellia Petal Blight

Tip description

Flower damaged by camellia petal blight, by Jack Kelly Clark, UC
Camellias are beautiful except when the flowers turn a blotchy brown. This petal blight is caused by a fungus that continues to live in the soil once a plant is infected. To reduce outbreaks, pick off all infected flowers and dispose of them in green waste. Home composting is not hot enough to destroy the pathogen. After blooming, pick up any petal debris. Then spread fresh mulch around and beyond the bush (but keep the mulch a few inches away from the trunk).
