I have many Lilies . Some years ago I discovered botrytis on some of the Lilies, and No one can give me any good advice for what to do. Must I stop growing Lilies (they don`t look nice when attacked by this (fungus?). Hope you have a good advice for me .
Thank you for your email. If you’re certain it is botrytis (a fungus that spots the leaves) then it’s caused by damp. Are your lilies in the shade? If so, you should lift your lily bulbs and replant them in a sunny position and/or in pots. Try to plant your lilies where they will dry out after rain to prevent Botrytis. If you do see brown spots on your leaves, spray with a fungicide recommended for roses. If you have noticed any yellow circles and gnarled leaves, then this could be a virus and the lily bulbs will need destroying unfortunately.
