rhododendron

Rhododendron 'Hawaii' requires weekly to bi-weekly watering, depending on the humidity levels in the area. The best time to water this plant species is in the morning or evening, when the temperature is cooler and the roots can absorb the water best. Make sure you water the soil thoroughly so the water reaches the root system. When the top 2-3 inches of soil begin to feel dry, it's time to water again. Avoid over-watering your rhododendron since this can cause root rot.

Rhododendron 'Hawaii' does best when given partial to full shade in the afternoon, since it is particularly sensitive to the intensity of direct sunlight. It can tolerate a few hours of morning sun, but too much direct sunlight can damage the leaves. In general, for best results, a minimum of 7 hours of indirect sunlight each day is recommended.

Pruning is important for Rhododendron 'Hawaii' to maintain a neat shape and to encourage new growth. Prune any dead or unhealthy branches in the spring or summer. Remove branches that cross over other branches or appear congested. Prune at a 45-degree angle just above a healthy bud. Pruning too much at 1 time can stunt further growth, so prune lightly and gradually over a period of years. The majority of trimming for Rhododendron 'Hawaii' should be done in late spring (May or June), as the plant is beginning its active growth phase. Avoid pruning in the fall, as cut stems may be damaged by cold temperatures.
