Chives in Zone 7B — Mid-Atlantic

Chives are a fantastic addition to any Mid-Atlantic garden. Their mild onion flavor elevates everything from eggs to salads, and their pretty purple flowers attract pollinators. Plus, they're incredibly easy to grow in our four seasons, providing fresh flavor from late spring well into fall.

Our humid summers and occasional deer pressure can present challenges, but with a little attention to timing and placement, you can enjoy a thriving chive patch. Our 214-day growing season provides ample opportunity for multiple harvests.

Starting chives indoors isn't essential, but it can give you a head start, especially if you want a sizable clump ready to harvest early. Sow seeds indoors from mid January through early February, about eight weeks before you plan to transplant. Use seed trays with a good seed-starting mix, keep them consistently moist (bottom watering works well), and provide warmth and light.

Since our springs can be variable, starting indoors gives you more control over the initial growing conditions. Once the seedlings have a few true leaves, they'll be ready to gradually acclimate to outdoor conditions before transplanting.

Transplant your chive seedlings outdoors from mid March through mid April, after the danger of a hard frost has passed. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the temperature swings and sunlight.

Space plants 8-12 inches apart in a sunny or partially shaded spot. While you *can* start from seed, many Mid-Atlantic gardeners find that buying established starts or dividing existing clumps is a much faster way to get a productive chive patch.

Direct sowing chives is a perfectly viable option, especially if you're not in a rush. Sow seeds directly into the garden from early March through late July. Choose a spot with well-drained soil and good sun exposure.

Keep the soil consistently moist until the seeds germinate. Be aware that chives are slow to establish from seed, so it may take a while before you have a substantial harvest. Divisions or starts will always be quicker!

Chives need moderate, consistent watering, especially during our humid summers. They're more tolerant of moisture than some other herbs, but they still don't like to sit in soggy soil. The key is finding the right balance.

During the hotter months, check the soil moisture regularly. Stick your finger about two inches deep; if it feels dry, it's time to water. Aim for about one inch of water per week, either from rainfall or irrigation. Water at the base of the plants to avoid wetting the foliage, which can encourage fungal diseases in our humid climate.

In spring and fall, you can usually reduce watering frequency. Overwatering can lead to bulb rot, especially in our clay soils, so watch for yellowing leaves or a mushy base. Underwatering, on the other hand, will cause the leaves to wilt and turn brown. A layer of mulch around the base of the plants will help retain moisture and regulate soil temperature, which is useful in our variable climate.

You can expect your first chive harvest from late May through early November in the Mid-Atlantic. Once the plants are about 6 inches tall, you can start snipping leaves. The best time to harvest is when the leaves are a deep green and the plants are actively growing.

To harvest, use sharp scissors to cut the leaves about 1-2 inches above the base. This encourages new growth and keeps the plants producing throughout the season. Continuous harvesting is key to keeping your chives productive.

As the first frost approaches in early November, you can either let the chives die back naturally or pot up a clump to bring indoors for winter use. Don't forget to divide your clumps every three years or so to maintain vigor!

Here are some common problems you might encounter with chives in the Mid-Atlantic:

Onion Fly

• What it looks like: Wilting or yellowing leaves, stunted growth, and small white maggots around the base of the plant.
• What causes it: Onion flies lay their eggs near the base of onion family plants, and the larvae burrow into the bulbs.
• How to fix/prevent it: Use row covers to prevent flies from laying eggs. Remove and destroy infested plants. Encourage beneficial nematodes in the soil.

Rust

• What it looks like: Rusty orange, yellow, or brown pustules on leaves and stems, mostly on undersides. Leaves yellow and drop prematurely.
• What causes it: Various rust fungi that spread via wind-borne spores. Favored by warm, humid conditions with moisture on leaves.
• How to fix/prevent it: Remove affected leaves. Avoid overhead watering. Improve air circulation. Apply sulfur or copper fungicide. Don't work among wet plants. Rotate crops.

Bulb Rot in Wet Soil

• What it looks like: Yellowing leaves, stunted growth, and a mushy, foul-smelling base.
• What causes it: Overwatering or poorly draining soil, especially in our heavy clay soils, can lead to bulb rot.
• How to fix/prevent it: Improve soil drainage by adding compost or other organic matter. Avoid overwatering. Plant chives in raised beds if drainage is a persistent problem.

Mid-Atlantic Specific Challenges: Our moderate-to-hot heat and humid summers create ideal conditions for fungal diseases like rust. Even rainfall means you must monitor soil moisture carefully to prevent bulb rot, especially if you have clay soil.

Chives make excellent companions for a variety of plants in the Mid-Atlantic garden. They deter pests and can even improve the flavor of some vegetables.

Good companions include carrots, tomatoes, roses, and grapes. Carrots benefit from chives' pest-repelling properties, while tomatoes are said to have improved flavor when grown near chives. Roses benefit from chives' ability to deter aphids, and grapes benefit from their ability to deter Japanese beetles. Avoid planting chives near beans or peas, as they can inhibit their growth.
