How to grow Garden Sage in Tucson & the low desert
Watering
Drought-tolerant once established; water deeply but infrequently and let the top of the soil dry between waterings. Excellent drainage is critical, as it is prone to root rot in wet or heavy soil.
Fertilizer & nutrients
Very light feeder. A single spring feeding of balanced/all-purpose fertilizer or compost is enough; too much nitrogen produces floppy growth and weaker flavor.
Pruning & care
Prune lightly after flowering and harvest regularly to keep it compact. In early spring, cut back leggy, woody stems by up to one-third to renew the plant; avoid cutting into bare old wood.
Notes
A reliable woody perennial in Tucson. Plant transplants in fall (best, so it roots through the cool season) or early spring. Give full sun with summer afternoon shade and sharp drainage; protect from prolonged soggy soil during monsoon. Drought-tolerant and long-lived when not overwatered. Grows well in pots.
