I'm about to leave for 10 days and it's a late spring. What to do? Put my too-big transplants in the garden and hope it doesn't freeze, or leave them in the greenhouse where they'll get too leggy?
I compromise and plant only the biggest ones, Red Sun sunflower, Galego Greens (collards from Spain), kale, vitamin green. After I left, my husband put in the leeks a friend had given me.
In the past several years, the weather was warm enough by May 15 to transplant, and plant seeds. Not this year! When the birch leaves are opening, that's when it's time.
