WaterAzaleas, including the 'White Lights' variety, prefer consistently moist but well-drained soil. They should be watered deeply whenever the top inch of soil feels dry to the touch, which may be once or twice a week depending on the weather conditions. It’s essential not to let azaleas dry out completely, yet overwatering can lead to root rot. A general guide is to provide about one inch of water per week, which is approximately 0.62 gallons per square foot. During hot or windy weather, the frequency may need to increase, whereas in cooler, rainy periods, it may decrease.
LightAzaleas, like the 'White Lights', thrive in dappled sunlight or partial shade. They benefit from protection against the hot afternoon sun, which can scorch their leaves. An ideal spot might be under the canopy of tall trees that filter sunlight. Morning light with afternoon shade or light that is filtered through a thin curtain if grown indoors is optimal for these plants.
TemperatureAzaleas, including 'White Lights' azaleas, are hardy in a range of temperatures but perform best in conditions that mirror their native habitat. They can typically survive in temperatures as low as 0°F and as high as 80°F, but the ideal range for vibrant blooms and growth is between 50°F and 70°F. Extended exposure to temperatures outside this range can cause stress and might impact flowering and overall health.
Pruning'White Lights' azaleas should be pruned to maintain health and shape, as well as to encourage bushier growth and more blooms. The best time to prune these azaleas is just after they finish blooming in spring, as azaleas set next year's bloom buds soon after the current year's flowers fade. Remove any dead or diseased branches, thin out dense areas to improve light penetration and air circulation, and shape the plant as desired. Prune sparingly, as excessive pruning can reduce flowering.
CleaningAs needed
SoilRhododendrons, including 'White Lights', thrive in well-draining, high-organic-content soil with a pH of 4.5 to 5.5. The best soil mix consists of equal parts peat moss, pine bark, and either perlite or coarse sand to ensure proper drainage and aeration.
RepottingRhododendrons, like 'White Lights', generally require repotting every 2 to 3 years, or when they become root-bound. It is best done in late winter or early spring before new growth begins.
Humidity & MistingRhododendron 'White Lights' prefers a humidity level between 40-60%. These plants appreciate a moist environment, but it's important to avoid overly wet conditions to prevent root rot.
Suitable locationsIndoor
Grow 'White Lights' Rhododendron in a cool spot with bright, indirect light.
Outdoor
Plant 'White Lights' Rhododendron in partial shade with moist, acidic soil.
Hardiness zone

Life cycle'White Lights' Rhododendron starts its life cycle as a seed, which upon germination, grows into a seedling with basic root and shoot systems. As it matures into a young plant, it develops a woody stem and foliage with its characteristic leaves. The Rhododendron then enters a period of vegetative growth, increasing in size and producing more leaves. Once mature, usually after several years, it begins its reproductive stage, producing clusters of white to pale pink flowers in the spring. After pollination, typically by bees or other insects, the flowers give way to seed capsules containing numerous tiny seeds. Each year, the plant may go through a period of dormancy, typically in the winter, before resuming growth in the spring.
PropogationPropogation time
Spring-Early Summer
Propogation: Rhododendron 'White Lights', commonly known as the White Lights Azalea, is most successfully propagated through semi-hardwood cuttings. This form of propagation is typically done in late summer, after new growth has partially matured and hardened. To propagate, select healthy semi-hardwood branches and make a cutting roughly 4 to 6 inches long, ensuring a few leaves remain on the cutting. The cut end should be dipped in rooting hormone to encourage root development, and then the cutting should be planted in a mix of peat and perlite or a similar well-draining medium. The cutting should be kept moist and in indirect light until roots have formed, which can take several weeks to a few months. During this time, it's crucial to maintain high humidity around the cutting, which can be achieved by placing a plastic cover over the pot or propagation tray.
