Care Guide
Planting
Plant your Alameda Manzanita in full sun - this is non-negotiable for healthy growth. The Calscape data doesn't specify soil type or drainage requirements, so research your local conditions or contact a Bay Area native plant nursery for soil guidance specific to your site. Space it to accommodate its mature size of 6 to 13 feet tall, and plan to plant in fall or early winter to establish before summer drought.
After Planting
After planting, water regularly through your plant's first summer to establish a deep root system, then transition to drought tolerance - typical of native manzanitas once established. Prune minimally and only after flowering ends (March or later), as manzanitas don't regrow from old wood like some shrubs do. Year one is about root establishment; expect slower visible growth than you might with non-native plants. The #1 mistake is overwatering once the plant is past its first season - Alameda Manzanita is adapted to our dry summers and will decline in wet conditions.
