Chives in Zone 5B — Mid-Atlantic

Chives are a fantastic addition to any Mid-Atlantic garden. Their mild onion flavor elevates everything from scrambled eggs to baked potatoes, and they're so easy to grow right here in our four-season climate. Plus, the cheerful purple blossoms are a welcome sight in the spring.

We Mid-Atlantic gardeners know our springs can be a bit unpredictable, and our summers bring plenty of humidity. But don't worry, Chives are quite resilient, and with a little planning within our 178-day growing season, you'll have a thriving patch in no time.

Starting Chives indoors is an option, but honestly, it's usually not necessary here in the Mid-Atlantic unless you're after a *really* early harvest. If you want to get a head start, sow seeds indoors from early to late February, about eight weeks before you plan to transplant them outside.

Use seed trays filled with a good seed-starting mix, and keep them in a warm spot with plenty of light – a sunny windowsill or under grow lights works well. Bottom watering helps keep the soil consistently moist without overwatering, which is especially important in our moderate spring climate.

Once the weather starts to settle in early April through early May, and you're confident we're past any late frosts, it's time to transplant your Chives seedlings outdoors. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week.

Choose a spot with full sun to partial shade, and space the plants 8-12 inches apart. Keep an eye on the weather forecast during this time; we can still get some unexpected cold snaps, so be prepared to cover the young plants if needed. Remember, buying established starts or dividing existing clumps is a faster way to get a mature plant.

Direct sowing Chives is a perfectly viable option here in the Mid-Atlantic, and it's super simple. You can sow seeds directly into the garden from late March through mid July.

Make sure the soil is well-drained and has warmed up a bit. Sow the seeds about ¼ inch deep, and keep the soil consistently moist. Be patient, as Chives can be slow to establish from seed. Again, divisions or purchased starts will give you quicker results.

Chives need consistent moisture, but they don't like to sit in soggy soil, especially with our humid summers. Aim for moderate watering throughout the growing season. We get fairly reliable rainfall here, but you'll still need to supplement, particularly during drier spells.

A good rule of thumb is to check the soil moisture about two inches down – the "finger test." If it feels dry, it's time to water. Typically, an inch of water per week, including rainfall, is sufficient. Water at the base of the plants to avoid wetting the foliage, which can encourage fungal diseases in our humid conditions.

Overwatering can lead to bulb rot, while underwatering will cause the leaves to turn yellow and droop. A layer of mulch around the plants will help retain moisture and suppress weeds, which is a great practice given our even rainfall.

You can expect your first harvest of Chives around mid June through late October, about 80 days after sowing. Look for leaves that are at least 6 inches tall.

To harvest, simply snip the leaves about 1-2 inches above the base of the plant. This encourages new growth and keeps the plant producing throughout the season. You can harvest continuously as needed.

As the first frost approaches in mid- October, cut back the entire plant to a few inches above the ground. This will encourage fresh growth in the spring. Every three years or so, divide the clumps to keep them vigorous and prevent overcrowding.

Here are some potential problems you might encounter with Chives in the Mid-Atlantic:

Onion Fly

• What it looks like: Seedlings wilt and die. Bulbs are tunneled with larvae.
• What causes it: Onion flies lay eggs near the base of plants. The larvae then burrow into the bulbs.
• How to fix/prevent it: Use row covers to prevent the flies from laying eggs. Remove and destroy any infested plants. Encourage beneficial insects like parasitic wasps.

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 foliage, stunted growth, and mushy, rotting bulbs.
• What causes it: Overwatering or poorly draining soil, especially during our periods of heavy rainfall, creates an environment where fungal pathogens thrive.
• How to fix/prevent it: Ensure good drainage by amending clay soil with compost. Avoid overwatering. Plant in raised beds if necessary.

Mid-Atlantic Specific Challenges: Our moderate-to-hot summers combined with high humidity can create an environment that favors fungal diseases, such as rust. Be vigilant about providing good air circulation and avoiding overhead watering. The consistent rainfall also means paying attention to soil drainage to prevent bulb rot.

Chives are great companions for several plants in the Mid-Atlantic garden. Carrots benefit from Chives because the oniony scent deters carrot root flies. Tomatoes also appreciate Chives nearby, as they can help repel aphids and other pests.

Roses benefit from the pest-repelling qualities of chives, too, and some say they improve the fragrance of roses. Grapes also benefit from the pest-deterrent qualities of chives.

Avoid planting Chives near beans and peas, as they can inhibit their growth.
