In response to a question we Master Gardeners get this time of the year -- is it too soon to plant . . . petunias, tomatoes, zininias, what have you. Yes it is too early. The last frost date for our climate zone is April 15th. Then it takes some time for the soil to warm up, especially at night. So even though this weekend may touch 80, it is way too early to plant anything which thrives in warm weather--including tomatoes and summer bedding plants. Not only will they pout, they may die; but they will not grow or flourish, causing the gardener to go back to the store for more. So wait a bit on warm weather plants. But you can plant some potatoes, maybe some lettuce, or a few onions. I have seen some beautiful perennials that can go in the ground now but they are early bloomers. Spend a bit of time at ACES.edu and see what the experts recommend for planting now.
Use these beautiful days to prepare your garden for your summer planting, apply fresh mulch to existing plantings, do a soil test, and think about what you are going to do. Then when the weather warms for good just do it.
