WaterRhododendrons, including 'Birthday Girl', prefer consistent moisture, so water them with about 1 inch of water per week. During hot or dry spells, increase watering to twice per week, ensuring the soil stays moist but not soaked. The roots are shallow, so it's important to water at the base and avoid wetting the foliage to prevent disease. In the winter, reduce watering but do not allow the soil to completely dry out.
LightRhododendrons like 'Birthday Girl' thrive in partial shade to filtered sunlight. They should be planted in a spot where they can receive morning sunlight but are protected from the harsh afternoon sun. An ideal location would be under the canopy of tall trees that provide dappled sunlight.
Temperature'Birthday Girl' Rhododendrons prefer temperate climates and are hardy in USDA zones 5 through 8. They can typically handle temperatures as low as 10°F and as high as 80°F, but they thrive between 60°F and 70°F. Avoid locations where winter winds may desiccate the foliage or where summer heat could stress the plant.
PruningPruning 'Birthday Girl' Rhododendrons is best done soon after blooming to shape the plant and remove spent flower clusters, which encourages healthy growth and better blooms the following year. Typically, it's not necessary to prune them annually, but doing so every 2 or 3 years can invigorate the shrub. Always use clean, sharp tools to make clean cuts.
CleaningAs needed
SoilAzaleas prefer well-draining, acidic soil with a pH of 4.5 to 6.0. A mix of 50% peat moss or well-rotted pine bark and 50% perlite or coarse sand is ideal to ensure proper drainage and aeration.
RepottingAzaleas should be repotted every 2 to 3 years, or when they outgrow their current container, using a suitable acidic soil mix.
Humidity & MistingAzaleas enjoy moderate to high humidity levels, ranging from 50% to 70%, which mimic their native, moist environments.
Suitable locationsIndoor
Place in bright, indirect light with humid environment and cool temps.
Outdoor
Partial shade, sheltered, acidic soil, protect from strong winds.

Life cycleThe Rhododendron 'Birthday Girl' begins its lifecycle as a seed, which, when sown in well-drained, acidic soil and exposed to the right temperature and moisture conditions, will germinate and sprout within weeks to months. Following germination, it enters a juvenile vegetative stage wherein it focuses on root and foliage development; during this time, early leaves emerge and photosynthesis begins, although it may take several years before it reaches maturity. Eventually, it transitions to a mature plant capable of flowering, often coinciding with spring where it produces large, pink, trumpet-shaped flowers that attract pollinators. After pollination, the flowers give way to seed pods that will mature and eventually disperse seeds, continuing the reproductive cycle. In the absence of extreme cold, pests, or disease, the Rhododendron 'Birthday Girl' can enjoy a long life, entering a period of senescence as it ages, during which growth slows and the plant may produce fewer flowers before eventually dying. Regular pruning, proper watering, and fertilization can extend the plant's life span and enhance its flowering capacity.
PropogationPropogation time
Spring-Early Summer
Rhododendron 'Birthday Girl', commonly known as the Birthday Girl Rhododendron, is usually propagated by semi-hardwood cuttings. This method involves taking cuttings from the current year’s growth in late summer, after the wood has started to harden but before it becomes completely woody. Ideally, the cuttings should be about 4 to 6 inches (10 to 15 cm) in length and include several sets of leaves. The lower leaves are removed, and the cut base of the cutting is dipped in rooting hormone to encourage root development. Then, the prepared cuttings are placed in a well-draining rooting medium and kept in a humid environment until roots have developed, which can take several weeks to a few months. It is important to maintain consistent moisture and to protect the cuttings from direct sunlight during this period.
