We are in USDA Planting Zone 7
Plant tomato, pepper, watermelon, canteloupe, cucumber, okra and pumpkin seed in 3 inch plant pots to grow your own plants for the summer garden. Place pots in a greenhouse or under florescent lights. Watermelon, canteloupe, cucumber, okra and pumpkin seed can be planted directly in the garden later however growing plants gives me a head start before the outdoor temperatures are warm enough.
Plant carrot, beet, and garden pea seed directly in the garden.
Plant cabbage, lettuce, onion, broccoli and strawberry (for berries next spring) plants plus shallots and potatoes in the garden.
