Care Guide
Planting
Plant Bert Johnson Manzanita in full sun or part afternoon shade in a location with fast-draining soil - it thrives in sandy soil but will tolerate clay as long as water doesn't sit. Space plants to account for mature spread, which can reach 4 feet. The best planting season in the Bay Area is fall through early spring so roots can establish before summer heat. Avoid planting near direct salt spray if you're in a coastal location.
After Planting
Water weekly for the first summer, then taper to no more than twice monthly once established - this is a very low water plant and overwatering is the main killer. After the first year, you can rely almost entirely on rainfall except during extended dry spells. The plant is evergreen and blooms winter through spring with minimal pruning needed; light shaping after flowering will maintain its mounded form. Expect slow, steady growth in year one; this is normal and the plant will fill in over time.
