Texas in USDA Zones 6–10
Texas spans Zones 6–10. Variety lists below are organized by zone — start with your zone for the most accurate recommendations.
Growing Alliums in Texas
Zone 8 offers allium growers a sweet spot that many northern gardeners envy—mild winters that allow for successful overwintering of garlic and shallots, plus a long growing season that lets you experiment with both short-day and intermediate-day onion varieties. The key challenge here isn't surviving cold snaps, but managing the transition from cool, wet springs to hot, humid summers that can stress bulbing alliums just when they need consistent moisture.
When selecting alliums for Zone 8, prioritize varieties that can handle temperature swings and have good disease resistance, especially to fungal issues that thrive in humid conditions. Look for cultivars that don't require extremely long cold periods (hardneck garlics can be tricky) but can still benefit from your reliable winter chill hours. The varieties listed here have proven themselves in Zone 8 gardens, offering everything from sweet storage onions that cure well in humid conditions to robust garlic varieties that won't bolt prematurely when spring temperatures spike.

Zone 8 Growing Tips for Texas
Your October through December window is prime time for planting garlic, shallots, and multiplier onions—they need those 12-16 weeks of cool weather to develop proper bulbs. Start onion seeds indoors in January or February, then transplant them out 2-3 weeks before your March 15 last frost date. The soil is usually workable by early March, and young onion transplants can handle light frosts just fine.
Row covers become your best friend during those unpredictable late February and March temperature swings that can stress young transplants or cause established plants to bolt prematurely. In summer, focus on consistent watering during the bulbing period (typically May through July) but back off as harvest approaches to prevent rot. Many Zone 8 gardeners struggle with fungal diseases during humid spells—ensure good air circulation and avoid overhead watering when possible.
Plant garlic deep (2-3 inches of soil cover) and mulch well to moderate soil temperature swings. If you're growing hardneck varieties, watch for scapes in May and remove them to encourage better bulb development.
