Preventing Botrytis on Lilies

This question was asked by
A. Gastad

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.

Advice on preparing lilies for overwintering

This question was asked by

Hi there,
I bought a couple of lily collections from you last year at the Wisley flower show – they’ve made a fantastic display in the garden this year. Thank you.
This has been my first experience with growing lilies and I am a little confused now with how far to cut them back in preparation for winter.
I have read lots of advice about pruning the seed heads and “allowing the foliage to die back naturally” but once the foliage has begun to turn brown, how much of the main stem or stalk should be cut back?
Hope you can help.

Hi there,
When the Lily has finished flowering, cut any seed heads back and allow the foliage to die back naturally as you say. Do not be tempted to cut the stem back until stems become hollow and brown. Once this has happened, you can cut the stem back to the service or leave about an inch of stem.
