Q.Whats the earliest for both collards and Swiss chard?
We live on the East Coast about 30 minutes from Charlottesville, Virginia and we’re about to put both collard greens and Swiss Chard out for our spring garden. I was wondering what would be the earliest time for both.
It is almost certain you will not get frost after May 7 in your growing zone.
You can grow these crops in a cold frame and plant much sooner.
