Care Guide
Planting
Plant your Mt. Tamalpais Manzanita in a location that receives full sun, as this native shrub thrives in bright conditions. Ensure the soil drains well - manzanitas are sensitive to soggy roots and will struggle in poorly draining soil. Space plants according to their mature size, which you'll want to confirm with your nursery since the exact dimensions aren't specified here. Plant in fall or winter when the plant can establish roots before the heat of summer.
After Planting
Water regularly during the first growing season to help your manzanita establish, then gradually reduce watering as the plant matures and becomes drought-tolerant. Avoid the common mistake of overwatering once established - this is a California native that prefers dry conditions and can develop root rot with excessive moisture. Pruning specifics aren't detailed in the available data, so check with a local native plant nursery or the California Native Plant Society for guidance on shaping and maintenance.
