Leaf Rollers In Monkshood

Question

I usually treat them with sevin powder but that product no longer available in Alberta. In ally found some BTK and sprayed it on today. I should hv done this weeks ago and now I’m afraid it’s too late. If I cut the plants back will they regrow and produce blooms?

Answer 1

This lovely, toxic plant should bloom again in the fall. If you prune them carefully and keep the spent flowers plucked it should be alright. Here are a couple articles:
