Care Guide
Planting
Plant your Brittleleaf Manzanita in full sun in fast-draining soil - ideally sandy or sandy loam, especially if you have hardpan underneath. The winter or early spring rainy season is your best window for planting in the Bay Area. Space plants 4-6 feet apart if you're creating a hedge, and avoid amending heavy clay soils; this plant prefers lean, well-draining conditions and won't tolerate soggy feet.
After Planting
Water your new plant weekly through the first summer, then taper to twice monthly once established - after year two, you should rarely need to water beyond what nature provides. The #1 mistake Bay Area gardeners make is overwatering; this is a chaparral plant adapted to drought, and excess water, especially in winter, causes root rot. Minimal pruning is needed; remove only dead or crossing branches in spring after flowering ends. Once established, this evergreen shrub is remarkably low-maintenance and cold-hardy to 5°F.
