watering

Water Roseshell azalea (Rhododendron prinophyllum) once or twice weekly depending on moisture levels in the soil. Be sure to thoroughly wet the soil each time. It's best to avoid underwatering and instead let the soil dry slightly between waterings. In the hot summer months, you may need to water more frequently. To test the soil moisture, poke your finger into the soil up to knuckle-depth, and if it feels dry, it's time to irrigate. Avoid overwatering, as this can cause root rot and other problems. If the container is allowed to dry out, deep soak it until water runs through the drainage holes.

sunlight

The roseshell azalea (Rhododendron prinophyllum) is best suited to part-sun locations, with morning sunlight and afternoon shade. Ideal light conditions are 4 to 6 hours of dappled sunlight to partial shade throughout the day. It is important to note that direct sunlight during the hot afternoon hours will cause the plant to become stressed, resulting in leaf burn and faded flowers. When choosing a planting spot, remember to avoid locations that are under the midday summer sun.

pruning

Pruning roseshell azalea (Rhododendron prinophyllum) is essential for its health and growth. Pruning should be done in late winter or early spring before bud break. With this particular species, it is best to prune only after all danger of frost has passed, usually in mid to late March for most areas. When pruning roseshell azalea, aim to remove dead, diseased or unruly branches. Thin out the inside branches to allow air and light to penetrate, and remove any competing branches. Prune younger branches to maintain the natural form of the shrub, and prune older branches to the ground to stimulate new growth. Avoid cutting back more than 1 third of the overall plant. It may take several pruning sessions to shape and maintain a roseshell azalea. With each session, consider how the resulting shape will look and fit within the landscape, and take care to ensure the plant remains healthy and vigorous year-round.
