When to plant.
Timing is entirely dependent on the weather and it changes from season to season – last spring was a particularly cold and wet one, for instance, which resulted in poor germination.
• 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.
• By early May, it's time to plant larger leafy greens such as Swiss chard and kale.
• 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.
