How to Grow Chives in New Hampshire

Chives (Allium schoenoprasum) are a versatile and hardy herb that can thrive in various climates, making them an excellent addition to any garden. Particularly in New Hampshire, where the climate can be somewhat unpredictable, chives are among the first herbs to emerge in spring and can continue to grow well into fall. This article will guide you through the process of growing chives in New Hampshire, covering everything from site selection to pest management.

Understanding Chives

Chives are part of the onion family and are known for their delicate flavor and culinary versatility. They have a mild onion flavor that enhances salads, soups, and various dishes. Beyond their culinary uses, chives also produce beautiful purple flowers that can attract pollinators to your garden.

Benefits of Growing Chives

1. Easy to Grow: Chives are low maintenance and do not require extensive gardening expertise.
2. Perennial Plant: Once established, chives will return each year, providing a continuous harvest.
3. Pest Resistance: Their strong aroma deters many common garden pests.
4. Culinary Versatility: Chives can be used fresh or dried in various dishes.

Choosing the Right Location

Selecting an appropriate site is crucial for growing chives successfully in New Hampshire. Here are several factors to consider:

Sunlight Requirements

Chives thrive best in full sun but can tolerate partial shade. Aim for at least 6 hours of sunlight daily. In the warmer months, particularly during mid-summer, some afternoon shade might help protect the plants from extreme heat.

Soil Quality

Chives prefer well-drained soil that is rich in organic matter. The ideal pH level for chives is between 6.0 and 7.0. Before planting, test your soil using a home testing kit or by sending a sample to a local extension service.

Drainage Considerations

Good drainage is essential for chive health; soggy soil can lead to root rot. If your garden has heavy clay or compacted soil, consider amending it with compost or planting chives in raised beds where drainage is better.

Preparing the Soil

Once you’ve selected your location, it’s time to prepare the soil for planting:

1. Clear the Area: Remove any weeds, rocks, or debris from the garden bed.
2. Amend the Soil: Incorporate organic matter such as compost or well-rotted manure into the top 6-8 inches of soil to improve fertility and drainage.
3. Tilling: Loosening up the soil helps promote root growth.

Planting Chives

You can plant chives either from seeds or transplants (divisions from existing plants). Here’s how to do both:

Starting from Seeds

1. Timing: In New Hampshire, start seeds indoors about 8-10 weeks before the last expected frost date (typically early May) or sow directly in the garden around mid-April.
2. Sowing Seeds: Plant seeds about ¼ inch deep and 12 inches apart in rows spaced about 18 inches apart.
3. Watering: Keep the soil consistently moist until germination occurs, which usually takes 7-14 days.

Using Transplants

1. Dividing Existing Plants: If you have established chive plants, divide them every 3-4 years for healthy growth.
2. Planting Divisions: Each division should contain at least a few roots and green tops. Space them about 12 inches apart.

Caring for Chive Plants

Once planted, chives require minimal care but will benefit from regular attention throughout their growing season.

Watering

Chives prefer consistently moist soil but should not be waterlogged. Water them during dry spells—about 1 inch per week—ensuring the topsoil remains damp but not saturated.

Fertilizing

Chives do not require heavy fertilization; however, applying a balanced fertilizer (like 10-10-10) once in early spring can promote robust growth. Avoid excessive nitrogen as it may lead to lush foliage with fewer flowers.

Pruning

Regular harvesting encourages bushy growth and prevents flowering until you want it to occur (the flowers are edible too!). Snip off outer leaves near the base once they reach about 6 inches tall.

Harvesting Chives

You can begin to harvest chives within a few weeks of planting if grown from seed or shortly after planting divisions:

1. Timing: Harvest when leaves are at least 6 inches long.
2. Method: Use sharp scissors or garden shears to cut leaves at ground level; avoid pulling them out as this may disturb the plant’s roots.
3. Ongoing Harvest: You can continue harvesting throughout summer; just leave some leaves on each plant for continued growth.

Pest Management

While chives are relatively pest-resistant due to their strong scent, some pests may still pose a threat:

Common Pests

1. Aphids: Usually found on new growth; spray them off with a strong stream of water or use insecticidal soap.
2. Onion Flies: These flies can lay eggs near base plants; practicing crop rotation helps minimize infestations.
3. Slugs and Snails: They may nibble on leaves—setting out traps filled with beer can help control their numbers.

Disease Control

Chive diseases are fairly rare but may include:

• Fungal Diseases: Overhead watering can encourage fungal diseases; water at the base instead.
• Root Rot: Ensure good drainage and avoid overwatering to prevent root rot.

Winter Care for Chives

In New Hampshire’s colder months, chives will go dormant but don’t need extensive winter care:

1. Mulching: Apply a layer of mulch around the base before winter sets in; this protects roots from freezing temperatures.
2. Snow Cover: Snow acts as natural insulation—if there’s snow cover, let it stay!

Conclusion

Growing chives in New Hampshire is not only feasible but rewarding due to their ease of care and culinary benefits. By following these guidelines on site selection, planting techniques, care routines, pest management strategies, and winter care practices, you are set for a successful growing season ahead! Whether you’re planting them in your backyard garden or pots on your patio, fresh chives will enhance your meals while adding beauty and biodiversity to your outdoor space.
