Answer: Pumpkins should be planted a week or two after the last spring frost, pumpkin plants will not tolerate any cold and prefer warm soil. Lettuce can be planted a little before the last expected frost because it prefers to grow in cool weather. Once the weather turns hot for summer, most lettuce varieties will bolt or go to seed and taste bitter. But you can plant lettuce again in late summer and early fall as a fall crop. If you are willing to experiment, you could still try planting leaf lettuce and harvest using the cut and come again method to enjoy some before the weather turns.
