Zone 6 Planting Calendar: Key Vegetables to Sow Each Month

Gardening in Zone 6 offers a diverse growing season, allowing gardeners to cultivate a wide variety of vegetables throughout the year. Understanding the best times to sow each vegetable can lead to a more productive and rewarding garden. This planting calendar provides a month-by-month guide to help you plan your vegetable planting schedule effectively.

Understanding Zone 6

Zone 6, as defined by the USDA Plant Hardiness Zone Map, has an average minimum winter temperature of -10°F to 0°F (-23.3°C to -17.8°C). This climate allows for a long growing season, typically from early spring to late fall. Knowing your zone helps determine the optimal planting times for various vegetables, ensuring they mature successfully before the first frost.
