March is a transitional month for gardeners in Zone 6, signaling the beginning of the planting season. While the weather can still be unpredictable, there are several crops that can be sown or transplanted to ensure a fruitful harvest later in the year. Understanding what to plant in late winter can maximize your garden’s productivity and extend your growing season.
Early Spring Crops Suitable for March Planting in Zone 6
Zone 6 experiences a relatively cold winter, but with proper planning, you can start certain crops early. These crops are hardy enough to withstand the cooler temperatures and can be directly sown into the soil or started indoors for later transplanting.
Leafy Greens
- Spinach
- Lettuce
- Kale
- Swiss chard
These greens are cold-tolerant and can be sown directly into the garden beds as soon as the soil can be worked. Starting them early allows for an early harvest before the heat of summer sets in.
Root Vegetables
- Carrots
- Radishes
- Turnips
- Beets
Root crops can be directly sown into the ground in early March. They prefer loose, well-draining soil and benefit from a soil temperature of at least 40°F.
Indoor Starting Tips for Late Winter
Starting plants indoors can give you a head start on the growing season. Use seed trays with quality potting mix, and provide ample light and warmth. Transplant seedlings outdoors once the danger of heavy frost has passed.
Herbs
- Basil (start indoors)
- Cilantro
- Parsley
- Thyme
Herbs like cilantro and parsley can be started indoors in early March for transplanting later in spring. Basil and thyme prefer warmer conditions and should be started indoors for best results.
Additional Tips for Late Winter Planting
In Zone 6, always keep an eye on the weather forecast. Use row covers or cold frames to protect young plants from unexpected frosts. Soil preparation, such as adding compost and ensuring proper drainage, will improve germination and plant growth.
Remember to stagger planting times to extend the harvest period and to choose disease-resistant varieties suitable for early planting. With patience and proper care, your garden can thrive even in early spring.
