evergreen azalea

Every 2 weeks, evergreen azaleas (Rhododendron 'Karens') should be watered thoroughly. Always water in the morning, so that the leaves and other foliage has time to dry out before nighttime. Use lukewarm water and water at the base of the plant. In order for the azalea to thrive, the soil should be kept moist but not wet. Apply an even amount of water until it starts to collect in the tray underneath the container. Over-watering is a common issue with evergreen azaleas, so keep an eye on the amount of water being given. Never allow the plants to sit in standing water.

The amount and timing of sunlight for evergreen azalea (Rhododendron 'Karens') will depend on where the plant is located. In general, this species of Rhododendron prefers indirect, bright sunlight throughout the day, such as what is found in partial shade. It can tolerate up to about 4 hours of direct sunlight per day without any negative effects. Therefore, in most areas, morning sun and afternoon shade or dappled shade is ideal. Sunlight should be avoided during midday when it is hottest. In very warm climates with strong, direct sun, evergreen azalea should be planted in a location that receives filtered morning or late afternoon sun, with shade throughout the remainder of the day.

Pruning evergreen azalea (Rhododendron 'Karens') should be done in early spring, before the new growth appears. Use a pair of sharp, clean pruning shears and prune no more than about 1-third of the plant’s overall growth. Make sure to prune older, woodier stems and dead branches to promote new growth. Removing the last few flowers of the season in early autumn may improve the next year’s flowers.
