Seed Starting Question - Z6B
I live in Michigan and am interested when others are sowing their leaf lettuce, cole crops, and other cold weather veggies. My last frost date is 5/10 or 5/15. I read on another forum many are already planting broccoli / cauliflower. I thought these veggies should be transplanted 2 weeks before last frost. Lettuce 3-4 weeks before last frost.
I think all of these seeds should be sowed 6-8 weeks before last frost. Am I way off here? Please advise.
