WaterAzaleas, including the Rhododendron 'Cheer', prefer consistently moist soil, which means watering should occur when the top inch of soil feels dry to the touch. This may translate to watering every 7 to 10 days, but frequency can vary based on climate, weather, and soil conditions. Ensure you provide deep watering to encourage a strong root system, which may require around 1 to 1.5 gallons per plant, depending on size, every time you water. Avoid over-watering to prevent root rot, and ensure the plant has well-draining soil to support healthy growth. During the hotter months, watering frequency should increase, whereas, in cooler months, it can be reduced.
LightAzaleas, such as Rhododendron 'Cheer', thrive in dappled sunlight or partial shade. They do best in spots that receive filtered morning sun with protection from the harsh afternoon sun. An ideal location may be under the canopy of tall trees that allows speckled sunlight to come through or on the north or east side of a building, where it can receive gentle sun exposure.
TemperatureAzaleas, like the Rhododendron 'Cheer', prefer moderate climates and do well in a temperature range of 50°F to 80°F. They can withstand minimum temperatures down to about 20°F, but prolonged exposure to sub-freezing temperatures can damage the plant. The ideal temperature range for this azalea would be between 60°F and 70°F for optimal growth and bloom production.
PruningAzaleas, such as Rhododendron 'Cheer', should be pruned to maintain shape, encourage bushier growth, and remove dead or diseased branches. The best time to prune is immediately after the blooming period ends in spring to early summer, as this is before the plant sets buds for the next year. Pruning should be done sparingly, and selective thinning cuts are often better than shearing to preserve the natural shape of the plant.
CleaningAs needed
SoilThe best soil mix for Rhododendron, commonly known as azalea, should be well-draining, rich in organic matter, and slightly acidic with a pH of 4.5-6.0. A blend of pine bark, peat moss, and perlite is commonly recommended for optimal growth.
RepottingAzaleas like Rhododendron 'Cheer' should be repotted every 2 to 3 years or when they become root-bound. Spring, after flowering, is the best time to repot these plants.
Humidity & MistingAzaleas thrive in environments with high humidity, ideally between 40-60%. They benefit from regular misting or a pebble tray with water to maintain the necessary moisture levels around the foliage.
Suitable locationsIndoor
Place azalea in bright, indirect light, away from drafts.
Outdoor
Plant azalea in dappled shade, protect from afternoon sun.

Life cycleThe Rhododendron 'Cheer', commonly known as a hybrid rhododendron, begins its life cycle with seed germination, typically in a well-drained, acidic soil rich in organic matter. Following germination, the seedling grows into a young plant, developing a root system and foliage through photosynthesis. As it matures, the rhododendron enters a vegetative stage, where it focuses on leaf and stem growth, often over several years, preparing for the flowering stage. The plant reaches reproductive maturity and produces buds that bloom in the spring, showcasing its vibrant flowers, which is the key feature of this ornamental plant. After pollination by insects, the flowers develop into seed capsules, which upon maturity, release seeds to begin a new generation. During autumn and winter, the rhododendron may enter a period of dormancy, conserving energy and resources to survive through colder temperatures until the cycle renews with the next growing season.
PropogationPropogation time
Late winter-early spring
Rhododendron 'Cheer', commonly known as Rhododendron, can be propagated through the method of semi-hardwood cuttings. This process typically takes place during the late summer after new growth has begun to mature and harden slightly, usually around July to August. To propagate by cuttings, a healthy non-flowering shoot is chosen and a 4 to 6 inch (about 10 to 15 cm) section is cut just below a node. The lower leaves are removed, and the cut end is dipped into a rooting hormone to encourage root development. The cutting is then inserted into a pot filled with a mix of peat and perlite or a well-draining rooting medium. The pot should be kept in a well-lit area, out of direct sunlight, and maintained at a constant humidity by covering it with a clear plastic bag or placing it in a propagator. Roots typically form within several weeks, after which the new plants can be gradually acclimated to less humid conditions before eventually being planted out.
