I've grown Lupins for a few years, last year I had my first attack of these. They came on mass and the plant collasped.
I love Lupins and would like to have one in this garden. The plant that died was probably in too hot a place so if I grow any again I'll be planting in more of a partial shade situation.
Is hit and miss with these things or is more than likely to happen again? I'm not going to use chemicals and it's doubtful I'll do anything organic either.
