Care Guide

Planting

Plant your Western Azalea in partial shade - ideally at the edge of a woodland where it gets some sun for flowering but afternoon shade protection. Dig into moist, acidic soil rich with organic matter like peat or pine needles; Western Azalea is native to forested areas and won't thrive in poor, compacted soil. Space it with room to reach its mature size of 8–12 feet tall. Plant in fall or early spring to establish before summer heat.

After Planting

Water weekly for the first season, then taper to once weekly during summer once established. Expect your plant to go completely leafless in winter - this is normal and not a sign of death. The biggest mistake Bay Area gardeners make is overwatering after the first year or planting in full sun; Western Azalea evolved getting summer fog drip, not intense afternoon heat, so if you're not getting natural moisture from fog, supplement with deep watering rather than frequent shallow watering.
