How to grow Garlic Chives in Tucson & the low desert
Watering
A cold-hardy perennial clumping bulb—plant in fall or early spring from seed, divisions, or transplants. Water moderately and consistently while actively growing (about weekly, more in summer heat), letting the surface dry between irrigations; quite drought-tolerant once the clump is established.
Fertilizer & nutrients
Light feeder. Work compost into the bed at planting and apply a balanced fertilizer once or twice during the growing season for tender, productive foliage.
Pruning & care
Shear the clump to 1–2 in to harvest the flat leaves; it regrows repeatedly. Remove spent flower stalks before seed sets to prevent prolific self-seeding (it can naturalize and spread). Divide crowded clumps every few years.
Notes
One of the easiest, most reliable perennial herbs for Tucson—handles both heat and cold. Self-seeds readily, so deadhead spent flowers to keep it from spreading. Flat leaves (unlike the hollow leaves of common chives) carry a distinct garlic flavor.
