Light: Has the healthiest foliage and flowers most prolifically in sites with part sun – all day dappled light or morning sun with afternoon shade.

Soil: Prefers acidic soils that stay evenly moist, but with good drainage.

Water: Likes to be kept on the moist side, but not soggy.

Fertilizing: Apply compost to the soil surface every season, all azaleas benefit from high organic matter.

Pruning: Pruning isnā€™t necessary, but if youā€™d like to increase the abundance of rebloom you can trim it just after its big spring bloom. This encourages new growth, which will bloom more prolifically.

Other: Has shown improved lacebug resistance.
