watering

Rhododendron 'Henry's Red' should be watered deeply and thoroughly once per week. In the summer months, it may need to be watered more frequently depending on the weather conditions and the level of soil dryness. The soil should remain evenly moist but never soggy. During the winter months, the plant can reduce the frequency of watering. Additionally, if the leaves start to droop, this may be a sign that the plant needs to be watered. If so, water until the soil is evenly moist. Avoid over-watering as this could cause root rot and kill the plant.

sunlight

Rhododendron 'Henry's Red' should be planted where it can receive 4-5 hours of sunlight daily in the early morning or late afternoon, and then either partial or dappled shade the rest of the day. Rhododendrons will thrive in climates with ample rainfall and high humidity. You should avoid full sun exposure as full sun can cause sunburn on the leaves and too much direct sunlight will inhibit the production of flowers and foliage.

pruning

Pruning Rhododendron 'Henry's Red' is a necessary part of proper maintenance in order to maintain the desired size and shape, promote new growth, and ensure abundant blooming. It is best to prune in the late winter to early spring before new growth begins. Prune out dead, damaged, and diseased growth first. Next thin out the growth by removing excess, crossing, and upward growing stems. Then prune back any remaining stems by 1-third their original length. Finally, check for any areas that may need additional pruning. Pruning should be done after blooming has finished in the spring and repeated as necessary.
