Jeanne, I agree with Daisy about not planting too early... what are you planning to start? And when can you put tender things out in the garden? It looks like we're in a similar zone; I don't put tomatoes and peppers out until June 1st. I start my tomato seeds around April 15th and the peppers get started April 1st. Onions I do start considerably earlier and just planted a flat of those seeds today. Things like cukes and squash don't get started until about May 7th - they sprout and grow really quickly!
For what it's worth, I've had a lot better luck putting smaller plants outside than larger, overgrown ones.
