Garlic in Zone 7B — Texas

Growing garlic in Zone 7B Texas rewards you with bulbs that pack serious flavor punch compared to anything you'll find at the grocery store. Our long 255-day growing season lets you plant garlic cloves in early summer and harvest plump, fully-developed bulbs by late winter or early spring. The satisfaction of braiding your own homegrown garlic or roasting whole bulbs fresh from the garden makes this crop worth the patience it requires.

While Texas heat and unpredictable weather can challenge many crops, garlic actually thrives with our timing. You'll plant during the hottest part of summer when most other crops struggle, then let the bulbs develop slowly through our mild winter months. The key is working with our climate patterns rather than fighting them.

Wait until early to late June to plant your garlic cloves directly in the garden - this timing puts them in the ground during our peak Texas heat, which garlic actually needs to break dormancy and start root development. Plant individual cloves pointed end up, about 2 inches deep and spaced 4-6 inches apart in rows.

Choose your planting spot carefully since these bulbs will occupy the space for 8 months. Pick a location with full sun and well-draining soil that won't become waterlogged during our unpredictable rainfall seasons. The brutal summer heat right after planting helps trigger the garlic's growth cycle.

Skip any hardening off process since you're planting cloves directly rather than transplanting seedlings. Just get them in the ground during your June window and let Texas heat do its work.

Garlic needs consistent moisture but hates waterlogged soil, making our unpredictable 15-50 inches of annual rainfall both a blessing and a challenge. During the first month after planting in June, water deeply twice a week since the Texas heat will stress newly planted cloves. Use the finger test - stick your finger 2 inches into the soil, and water if it feels dry.

Once fall arrives and temperatures moderate, reduce watering to about 1 inch per week including rainfall. Our variable humidity means you'll need to watch soil moisture carefully rather than following a rigid schedule. Water at the base of plants rather than overhead to avoid encouraging rust and other fungal problems that love our humid spells.

Spring brings the most critical watering period as bulbs size up rapidly. Maintain that 1 inch per week through March, then stop watering completely 2-3 weeks before harvest when you notice the lower leaves browning. This drying period is essential for proper curing and storage.

Apply 2-3 inches of mulch around plants after the worst summer heat passes to help retain moisture and moderate soil temperature swings during our unpredictable weather patterns.

Garlic requires minimal pruning, but hardneck varieties will send up curly flower stalks called scapes sometime in late winter or early spring. Cut these off as soon as you notice them curling - this redirects the plant's energy back into bulb development rather than flower and seed production. Those scapes make delicious additions to stir-fries and salads, so don't waste them.

Leave all the leaves alone throughout the growing season since they're manufacturing the energy needed for bulb development. Even when some lower leaves start yellowing in spring, resist the urge to clean them up until harvest time approaches.

As our first frost approaches in mid-November, your garlic will still be actively growing underground. The mild winter weather keeps the foliage green and working, so there's no end-of-season cleanup needed until harvest time arrives in late winter.

Your garlic will be ready for harvest sometime from late January through mid-March, depending on when you planted and which variety you chose. Watch for the telltale sign: when the bottom third of leaves have turned brown while the upper leaves remain green. This usually happens about 240 days after planting.

Don't wait until all leaves are brown - you'll risk the bulbs starting to separate and losing their storage quality. Carefully dig bulbs with a garden fork rather than pulling them, since the stems can break easily when the soil is dry.

Brush off excess soil but don't wash the bulbs. Cure them in a dry, airy location out of direct sunlight for 2-4 weeks until the outer papery layers are completely dry and the stems have shriveled. Our Texas humidity can slow this process, so ensure good air circulation with fans if needed.

Plan your harvest timing around our unpredictable spring weather. A late freeze after harvest won't hurt cured bulbs, but try to get them out of the ground before any major spring storms that could waterlog the soil and make digging difficult.

White Rot White rot shows up as yellowing leaves that die back from the tips, often accompanied by white, fluffy fungal growth around the bulb base and roots. You might also notice small black structures (sclerotia) that look like poppy seeds in the soil around affected plants. This soil-borne fungus thrives in our warm, moist conditions and can persist in the soil for years. Remove affected plants immediately and don't compost them. Improve soil drainage and rotate garlic to a different bed for at least 3-4 years. Consider solarizing the soil during our brutal summer heat to help kill the fungus.

Rust Rust appears as orange, yellow, or brown pustules on leaf surfaces, primarily on the undersides, followed by yellowing and premature leaf drop. This fungal disease spreads through wind-borne spores and loves our warm temperatures combined with high humidity and wet foliage. Remove affected leaves immediately and avoid overhead watering during our humid spells. Improve air circulation between plants and apply sulfur-based fungicides if the problem persists. Never work among plants when they're wet from dew or rain.

Bulb Mites These tiny white mites feed inside garlic bulbs, causing them to become soft, moldy, and unmarketable. You'll often find them in storage rather than in the field, but they can attack bulbs in the ground during our wet periods. Infected bulbs may show brown, corky areas or feel soft when pressed. Prevent bulb mites by ensuring proper curing and storage conditions with low humidity. Avoid planting cloves from infected bulbs, and rotate crops to break the pest cycle.

Texas Specific Challenges: Our combination of extreme heat, variable humidity, and unpredictable rainfall creates perfect conditions for fungal diseases while also stressing plants in ways that make them more susceptible to pest problems. The key is managing moisture carefully and ensuring good air circulation, especially during our humid spells that can last for weeks.

Plant garlic alongside tomatoes and peppers since garlic's natural sulfur compounds help repel aphids and other soft-bodied insects that plague these warm-season crops during our long growing season. Brassicas like cabbage and broccoli also make excellent neighbors because they'll be growing during garlic's active period in fall and winter, and garlic helps deter cabbage worms and other brassica pests. Many Texas gardeners plant garlic around their rose beds since it helps discourage aphids while the roses are dormant in winter.

Avoid planting garlic near beans and peas because garlic can actually inhibit their growth and nitrogen fixation abilities. This is especially important in our two-season growing pattern where you might have fall beans overlapping with developing garlic bulbs. Keep these crops in separate beds to avoid any growth conflicts during our extended growing seasons.
