Hubby and I finished building some raised beds and I'm gearing up to plant. This will be my first attempt at growing cold season vegetables. The Vegetablegarden.info planting guide for my area - zone 8 - shows I can plant peas, cabbage and spinach starting 1/15. The guide also shows I can start collards on 2/1 and broccoli on 2/15. According to a cold temp tolerance chart put out by Purdue, these are all hardy vegetables. I'm guessing collards and broccoli need to be planted later due to soil temps slowing germination. Right?
If some frost hardy vegetables have to be started later because they just don't germinate well in cooler soil, would it be possible to start them in a flat and transplant? What I mean by that is can I get the seeds to germinate and transplant them into the garden right away before the plant has any true leaves? Would that work? The plants I have in mind are cabbage, collards and broccoli.
Thanks for your help!
