Rhododendron Rhododendron 'Albert Schweitzer'
ABOUT
The Rhododendron 'Albert Schweitzer' features an impressive display of large, showy flowers that exude a romantic ambiance in any garden setting. These blooms are typically a soft pink shade, but they can range from deeper rosy hues to lighter pastel tones. Each blossom is ornately textured, with a wavy or ruffled edge that adds to their opulent appearance. The petals themselves are known for their thickness, which gives the flower a lush, full look. At the center of each cluster of flowers, you can often spot speckled markings that provide a compelling contrast and draw in the eyes of admirers. Beyond its captivating flowers, the Rhododendron 'Albert Schweitzer' also boasts a lush tapestry of foliage. Its leaves are leathery to the touch, with a deep green color that serves as the perfect background to highlight the floral display. The shape of the leaves is elongated, tending to taper gently to a point.

WaterThe Rhododendron, commonly known as Azalea, should typically be watered once a week with 1 gallon of water, ensuring the soil is moist but not waterlogged. During hot, dry periods, increase watering frequency to twice a week. Conversely, reduce watering during the winter dormant period or in consistently wet conditions to prevent root rot. It is crucial to water thoroughly, allowing moisture to reach the root zone deep beneath the surface. For potted Azaleas, check the top inch of soil for dryness and water until it runs out of the drainage holes.
LightAzaleas thrive in conditions where they can receive partial shade, especially protection from harsh afternoon sun. An ideal spot is under the dappled shade of tall trees, which provides a mix of light and shade throughout the day. They can also perform well in spots with morning sun and afternoon shade, ensuring they aren't exposed to intense light that could damage their foliage.
TemperatureAzaleas prefer mild climates and can tolerate a range of temperatures; however, they do best when temperatures remain between 60°F and 80°F. Azaleas can withstand minimum winter temperatures down to 20°F, but prolonged exposure to cold or temperatures over 90°F can stress the plant. Adequate mulching can help the root system stay cool in summer and protected from cold in winter.
PruningAzaleas should be pruned for shaping, removal of dead or diseased wood, and to promote bushier growth. The best time for pruning Azaleas is soon after the blooms fade in the spring, as they set next year’s flower buds shortly thereafter. Avoid pruning after mid-summer, as it may remove those buds and reduce next year's blooms. They may require pruning every 2 to 3 years, depending on the desired size and shape.
CleaningAs needed
SoilRhododendrons require well-draining, acidic soil with a pH between 4.5 and 6.0. A mix of 50% pine bark, 30% peat moss, and 20% perlite serves well. Regularly check soil pH to maintain optimal acidity.
RepottingAzaleas, including 'Albert Schweitzer', should be repotted every 2-3 years or when rootbound. Spring is the best time for repotting to allow for growth.
Humidity & MistingRhododendrons thrive with high humidity levels between 40% and 80%, so they appreciate a moist environment not dry air, but avoid wet foliage.
Suitable locationsIndoor
Place in bright indirect light and keep soil moist.
Outdoor
Partial shade and shelter from strong winds is best.

Life cycleRhododendron 'Albert Schweitzer' begins its life cycle as a seed, typically requiring stratification to break dormancy before germination can occur in favorable conditions with warmth and moisture. After germination, the seedling develops true leaves and establishes a root system, gradually maturing into a young plant over the course of a few years. This rhododendron progresses to a vegetative state where it focuses on leaf and branch growth; during this stage, it is important to protect it from extreme conditions and pests. Upon reaching maturity, the plant begins its reproductive stage, producing clusters of showy, pinkish flowers in spring to early summer, attracting pollinators which facilitate cross-pollination. After pollination, flowers give way to dry seed capsules that release seeds in late summer to autumn, thus completing its reproductive cycle. Mature rhododendrons can continue this cycle for many years, sometimes decades, given proper horticultural care, including adequate watering, fertilizing, and pruning to maintain health and vigor.
PropogationPropogation time
Spring-Early Summer
Propogation: The Rhododendron 'Albert Schweitzer' is commonly propagated by semi-hardwood cuttings, which is the most popular method for this variety. The ideal time for taking cuttings is late summer, after the new growth has partially matured and hardened off. You will need to select healthy, disease-free shoots and cut sections about 4 to 6 inches (10 to 15 centimeters) long. Remove the lower leaves and dip the cut end in a rooting hormone to encourage root development. Then, insert the cutting into a pot filled with a mix of peat and perlite, ensuring at least two sets of leaf nodes are buried. Place the cuttings in a warm, humid environment with indirect light, and keep the soil consistently moist but not waterlogged. Roots typically develop in several weeks, after which the new plants can be slowly acclimatized to less humid conditions and eventually transplanted.
