Growing cilantro in Zone 6 can be a rewarding experience for gardeners who enjoy fresh herbs in their cooking. Cilantro, also known as coriander, thrives in cool weather and can be grown successfully with some planning and care. This guide provides tips on how to grow and preserve cilantro in Zone 6’s climate.
Understanding Cilantro and Zone 6 Climate
Zone 6 experiences cold winters and warm summers, with average minimum temperatures ranging from -10°F to 0°F. Cilantro prefers temperatures between 50°F and 85°F and tends to bolt (go to seed) quickly in hot weather. Therefore, timing and location are crucial for successful cultivation.
Planting Cilantro in Zone 6
Start cilantro seeds indoors 4-6 weeks before the last expected frost date or sow directly outdoors once the soil warms up in early spring. Choose a sunny spot with well-draining soil rich in organic matter. Sow seeds about 1/4 inch deep and space them 6 inches apart.
Transplanting Seedlings
If starting indoors, transplant seedlings outdoors when they are 3-4 inches tall and the weather is consistently cool. Harden off seedlings by gradually exposing them to outdoor conditions over a week.
Caring for Cilantro
Keep the soil evenly moist but not waterlogged. Mulching around plants helps retain soil moisture and suppress weeds. Cilantro benefits from regular watering, especially during dry spells.
Managing Bolting
To prevent cilantro from bolting, plant in the cooler parts of the year and provide some afternoon shade during hot days. Harvest leaves frequently to encourage bushier growth.
Harvesting Cilantro
Harvest cilantro leaves once the plants are 6-8 inches tall. Cut leaves from the top, allowing new growth to develop. For seeds, let some plants go to seed and collect the coriander when seed heads turn brown and dry.
Preserving Cilantro
Preserve cilantro in several ways to enjoy it year-round:
- Freezing: Chop cilantro leaves and pack into ice cube trays with water or olive oil. Freeze and use in cooked dishes.
- Drying: Hang bunches upside down in a well-ventilated, dry area. Once dried, crumble leaves and store in airtight containers.
- Making Pesto: Blend cilantro with garlic, nuts, olive oil, and cheese to create a flavorful pesto that can be frozen in small portions.
Additional Tips for Success
Use container gardening for better control over soil and microclimate. Consider planting cilantro in the early spring and late summer for continuous harvests. Regularly remove seed heads to prolong leaf production and enjoy fresh cilantro throughout the growing season.
