I was wondering when the best time to repot my Lilies would be. They suffered rather badly from lily beetle this year. Should I wait until they have completely died back? The bulbs I bought from your stand at Gardeners World live have been wonderful.
Have you tried using Neem Oil on your lilies to prevent the Lily beetle from attacking them? If not, try mixing 5ml Neem Oil with 1litre of Water and a squirt of Washing Up Liquid. Spray once a week with a fresh mix.
Regarding repotting your lilies, I would leave them in until they have died back completely. It will probably be later Autumn by this time.
