Calvin you won't run into this but for you Northern growers a history lesson About 20 years ago up in these here White Mountains, The weather was like Calvins in March about 3 months ahead of schedule. After about 3 weeks of it I planted out everything. On May 10th we had 24in (about 2/3M) of heavy wet snow. Lost all the non-frost hardies. Too late to start over, Had to settle for some mislabeled Nursery stuff. Now I start some extras just in case. Sometimes I win, most times I lose. Byron
