WaterThe Rhododendron falconeri, commonly known as the Falconer's Rhododendron, should be watered deeply to ensure that the soil around the roots is moist but never soggy. The frequency of watering depends on the weather and soil drainage, but generally, watering every 7 to 10 days during the growing season is adequate. It’s important to provide about 1 gallon of water for smaller plants and up to 2-3 gallons for larger, established plants per watering session. It's essential to reduce watering frequency in the winter when the plant is not actively growing. Over-watering can lead to root rot, so make sure the plant is in well-draining soil.
LightFalconer's Rhododendron thrives in dappled shade or partial sunlight. A spot that offers morning sunlight with afternoon shade, or light filtered through a canopy of trees, is ideal. Avoid placing it in direct, hot afternoon sun as this can damage the foliage. Consistent, indirect light will promote healthy growth and flowering.
TemperatureFalconer's Rhododendron prefers mild temperatures and a cool environment. Ideally, the temperature should range between 50°F and 75°F. It can survive minimum temperatures down to around 20°F but may suffer damage beyond this point. High temperatures over 80°F can stress the plant, especially if humidity is low. Keeping it in a temperature-controlled environment that doesn't fluctuate dramatically is best for its health.
PruningRegular pruning of the Falconer's Rhododendron is not necessary, but it may benefit from occasional trimming to remove dead or diseased branches and to maintain its shape. The best time to prune is immediately after the blooming period finishes in the spring, as the plant sets next year's flower buds soon after. Lightly shaping the plant every few years encourages rejuvenation and healthier growth.
CleaningAs needed
SoilRhododendron falconeri, commonly known as Falconer's Rhododendron, requires well-draining, acidic soil with a pH between 4.5 and 6.0. A mix of 50% peat, 30% pine bark, and 20% perlite or coarse sand is ideal for providing the necessary drainage and aeration.
RepottingFalconer's Rhododendron needs repotting every 2 to 3 years or when the roots outgrow the container. It's best done in late winter or early spring before new growth begins.
Humidity & MistingFalconer's Rhododendron prefers high humidity levels, ideally around 60-80%. To maintain these conditions, a pebble tray with water or a humidifier can help, especially during dry indoor conditions or in arid climates.
Suitable locationsIndoor
Place in bright, indirect light and keep soil moist.

Life cycleRhododendron falconeri, commonly known as Falconer's Rhododendron, begins its life cycle as a seed, which germinates in a moist, well-drained soil environment with partial shade. The seedling grows slowly, developing a root system and foliage, eventually maturing into a large shrub with thick, leathery leaves. Flower buds form, typically in protected areas within the plant's canopy. These buds bloom in late spring to early summer, producing impressive bell-shaped flowers that can be cream, yellow, or pink with prominent purple blotches. After pollination, typically by insects, the flowers develop into woody capsules containing numerous small seeds. These seeds are dispersed by wind and, if they land in suitable conditions, will germinate to continue the cycle.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method for propagating Rhododendron falconeri, commonly known as Falconer's Rhododendron, is through semi-hardwood cuttings. This technique is generally performed during the late summer, as the new growth starts to mature and harden slightly. For successful propagation, take cuttings from healthy parent plants, about 4 to 6 inches (10 to 15 centimeters) long, with several sets of leaves. The lower leaves are removed and the cut edge is often treated with a rooting hormone to encourage root development. The prepared cutting is then inserted into a well-draining potting mix, ensuring the leaf nodes, where roots will form, are buried. To maintain humidity and warmth, which are crucial for root formation, the pot is typically covered with a plastic bag or placed in a greenhouse environment. It usually takes several weeks to a few months for cuttings to root firmly, after which they can be potted separately and gradually acclimatized to outdoor conditions.
