Thank you so much for this article! I really enjoyed reading it. I live in zone 5 and picked up my rake the last weekend in March. Here is my question/concern...Last year I planted 2000 cosmo seeds on the hill next to my house. I left the cosmos alone all fall and winter until the end of March when I cleaned up (removing old stems and raking/tilling soil). I was hoping/expecting the cosmos to self sow and double but haven't seen anything yet. Our last date for frost is May 15th, today is April 23rd.
1. Did I ruin any chance for my cosmos to show their pretty face again?
2. When do they typically come up in spring? Is it just too early maybe? Do they have any chance of surviving?
Thank you in advance for your guidance! I am so worried!
