I am a very impatient person but have learned to wait. If you put out tomatoes now and again in a month they will fruit at very nearly the same time. Cold nights are not a tomatoes friend.

Years ago a sturdy by Organic Gardening found that small plants put out at the same time as larger ones actually reached maturity sooner. Go figure.

It is safe now to pant all leafy crops, peas, potatoes, cabbage, broccoli, beet, parsnips, etc. IMHO it is too early to plant beans, corn, pumpkins, squash, tomatoes, eggplants and any other heat loving plants.
