Care Guide
Planting
Plant Chaparral Mallow in full sun with well-draining soil - it tolerates fast, medium, or slow drainage as long as water doesn't pool. Spring is the ideal planting season in the Bay Area. Space plants according to your garden's size: if you have room, let them grow to their full 10–16 feet wide; in smaller gardens, plan for regular pruning to manage their fast growth.
After Planting
Water weekly during the first growing season to establish a strong root system, then transition to very low water once established - just once a month maximum in summer. Year two onward, this plant is extremely drought-tolerant and needs almost no supplemental water. Prune in late winter or early spring to shape and control size, especially if you're in a small space. The #1 mistake is overwatering after establishment; this plant thrives on neglect and root rot is a real risk in Bay Area winter rains without excellent drainage.
