Zone 6 Gardening Tips:

Frost Dates: Last frost ~April 15; First frost ~October 15 (check your local frost dates for precision).

Planting Indoors: Start seeds for tomatoes, peppers, and eggplants about 6–8 weeks before the last frost.

Soil Temperature: Warm-season crops like corn, tomatoes, and peppers need soil temperatures above 60°F.

Succession Planting: Use for crops like lettuce, radishes, and peas to extend the harvest season.

Cold Frames & Row Covers: Extend your growing season by protecting early spring crops or warming the soil for a faster start.
