Where are you? If you're in the northern hemisphere.. it's a bit late for cosmos. I've never heard of overwintering cosmos before.. but perhaps someone has?
Thanks for this everyone! I thought I was being really clever by planting up so early as I was late last year.. now I have 40 leggy cosmos seedlings to pot on! Your tips are really helpful!
Was just looking at my leggy cosmos and wondering what to do! I only sowed a few so will sow more later, but in the meantime I will pot them on with this curling method. Thank you!
