Chives in Zone 7A — Texas

Chives are a fantastic addition to any Texas garden. Their mild onion flavor elevates everything from scrambled eggs to baked potatoes, and they’re incredibly easy to grow. Plus, the purple flowers are a beautiful bonus that attract pollinators to your garden.

Sure, we face the challenge of Texas heat and unpredictable weather, but chives are surprisingly resilient when given the right conditions. With our long 245-day growing season, you can enjoy fresh chives for a good portion of the year, even squeezing in a fall harvest.

Starting chives indoors in Texas is definitely an option, especially if you're itching to get a head start. Begin in late December through mid January, about 8 weeks before you plan to transplant. This gives them a good head start before our early spring warmth hits.

Use seed trays with a good seed-starting mix, and keep them warm and consistently moist. Bottom watering is a great way to keep the soil evenly damp without overwatering. A simple grow light will ensure they get enough light.

Transplanting chives outdoors is best done in early to late March. Before you move them outside, harden them off for about a week by gradually increasing their exposure to the elements.

Space them about 8-12 inches apart in a sunny spot with well-draining soil. Keep an eye on the weather; those unpredictable late freezes can still sneak up on you, so be prepared to cover them if needed. Honestly, though, buying starts or dividing existing clumps is much faster and easier than starting from seed.

Direct sowing chives is certainly doable here in Texas, and you can do it from mid February through mid August. Prepare a well-draining seedbed and ensure the soil temperature is consistently above 60°F.

Sow seeds about ¼ inch deep, spacing them 8-12 inches apart. Keep the soil consistently moist until they germinate. Just be aware that chives are slow to establish from seed, so be patient. Again, divisions or starts are definitely the faster route to a thriving chive patch.

Chives need moderate, consistent moisture to thrive in our Texas climate. While they're more tolerant of moisture than many herbs, they definitely aren't drought-tolerant. During our hot-to-extreme summer months, you'll need to be extra vigilant.

In the spring and fall, aim for about 1 inch of water per week, either from rainfall or irrigation. During the peak of summer, that might need to increase to 1.5-2 inches per week, especially if we're experiencing a dry spell. Stick your finger about 2 inches deep into the soil; if it feels dry, it's time to water.

Water at the base of the plants to avoid getting the leaves wet, especially given our variable humidity, which can encourage fungal diseases. Overwatering can lead to bulb rot, so watch for yellowing leaves and a mushy base. Underwatering will result in droopy, wilted foliage. A layer of mulch will help retain moisture and keep the soil cooler during the scorching summer months.

You can expect your first harvest of chives from early May through late November in Texas. They're ready to harvest when the leaves are at least 6 inches tall.

Cut the leaves about 1-2 inches above the base of the plant. This encourages new growth, ensuring a continuous harvest throughout the growing season. Don't be afraid to harvest frequently; it actually promotes more growth.

As we approach our first frost in mid- November, give them one last good trim. You can even pot up a clump and bring it indoors to enjoy fresh chives throughout the winter. Every 3 years, dig up and divide the clumps to keep them vigorous.

Here are some common problems you might encounter with chives in Texas:

Onion Fly

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

• What it looks like: Yellowing or browning leaves, a soft and mushy bulb, and a foul odor.
• What causes it: Overwatering and poorly draining soil create ideal conditions for fungal and bacterial pathogens to attack the bulbs. Flash floods can definitely exacerbate this.
• How to fix/prevent it: Ensure well-draining soil. Avoid overwatering. Improve air circulation. Remove and destroy any affected plants.

Texas Specific Challenges: Our hot-to-extreme heat can stress chives, making them more susceptible to pests and diseases. Variable humidity and unpredictable rainfall can also create challenges, favoring fungal diseases one week and causing drought stress the next. Fire ants can also be a nuisance, so keep an eye out for their mounds and treat them accordingly.

Chives are great companions for several plants in your Texas garden. Carrots benefit from chives because they repel carrot root flies. Plant them near tomatoes to deter aphids and spider mites.

Roses love having chives nearby, as they help to prevent black spot and other fungal diseases. Grapes also benefit from chives' pest-repelling properties. Avoid planting chives near beans or peas, as they can inhibit their growth.
