I live in a small mountain community and we tell ourselves not to plant out anything until Mother's Day. It's hard not to get impatient, but we can get snow even into June. However, I am going to transplant some veggies outside in late April. I have started broccoli, cauliflower, cabbage and lettuce inside and outside with wintersowing and I am going to transplant them earlier than I have been because I keep reading that they can handle the cold. I also bought a frost blanket, just in case.
I started wintersowing last year, with flower seeds. It worked great and I am doing more this year, including veggies. But, I am also planting backups inside just in case. I am especially skeptical about WSing tomatoes and peppers, but I'm going to try it. But I get such a kick watching my inside seeds sprouting and growing, so I'll probably continue that too.
I'm hooked!
It's so great to be retired and have the time to do this.
