• As a general rule, the first seeds that go into the ground are unusually peas around mid-March.
• Early to mid-April also is the time to seed lettuces, carrots, and beets.

• The week following Memorial Day (or once the ground temperature has warmed to 65-75 degrees), is when to put your warm weather vegetables such as zucchini, tomatoes, peppers, and eggplants into the ground.
