I had good results starting seeds outside, in seed-starter trays, about two weeks before our last frost date. I kept them in our open wood frame and covered it with burlap during nights when temps were 37-40 degrees (I'd bring inside for frost-nights). Then, when overnight temps stabilized over 40 I transferred them to small pots, and finally put then in the ground at overnight 50 degrees. They are doing well in the ground now as the temps continue to warm. :}
