What Does Zone 6B Mean?
USDA Hardiness Zone 6B means your area's average annual extreme minimum winter temperature falls between -5°F to 0°F (-21°C to -18°C). This is the coldest temperature you can typically expect in a normal winter, based on 30 years of climate data.
Your zone primarily determines which perennial plants (trees, shrubs, perennial flowers, and fruit bushes) can survive outdoors year-round. It's also strongly correlated with your frost dates, which are the foundation for calculating when to plant annual vegetables and flowers. Learn more about what hardiness zones mean.

Frequently Asked Questions
Zone 6B is the sweet spot for temperate gardening. Genuine winters kill pests and vernalize bulbs, while warm summers ripen tomatoes, peppers, corn, and most warm-season crops reliably. The four-season cycle creates natural soil rest periods. Nearly every common vegetable, herb, and flower performs well here — you have few limitations.
Peas, lettuce, and spinach go out 3-4 weeks before your last frost (typically mid to late April). Tomatoes and peppers wait until 2 weeks after. Start warm-season seeds indoors 6-8 weeks before transplant. Fall gardening is your bonus season — plant cool-season crops in August for harvest through October and into November with light frost protection.
