Planting & Care

Select a location receiving partial shade with no more than four hours of direct sunlight daily. Dig a planting hole three times wider than the root ball and equally deep, then position the shrub and backfill while watering lightly to eliminate air gaps. Water newly planted specimens two to three times weekly during the first growing season, adjusting frequency during hot weather. Amend clay or alkaline soil with organic matter or coffee grounds to maintain the acidic conditions this plant prefers. Apply a slow-release azalea fertilizer in early spring, and prune lightly after flowering finishes to maintain shape and encourage fuller growth.
