Bell Rhododendron Rhododendron campylogynum

Water

The Rhododendron campylogynum, commonly known as Bell Rhododendron, requires consistent moisture but does not tolerate standing water. It should be watered deeply once a week, ensuring that the soil is moist but not saturated. During the growing season, depending on the weather conditions, you might need to increase the frequency to twice a week, especially if the weather is dry or windy. It is essential not to let the Bell Rhododendron dry out completely, which could damage the plant. Aim to provide about 1 gallon of water per week for a young plant, adjusting for rainfall and as the plant grows.

Light

Bell Rhododendron thrives best in partial shade to filtered sunlight. It should be planted in a spot that is shielded from harsh afternoon sun, which can scorch its leaves. Morning light with afternoon shade or dappled sunlight throughout the day is ideal for this plant. Avoid deep shade as well, which can lead to poor flowering and weak growth.

Temperature

Bell Rhododendron prefers cool to moderate temperatures with an ideal range between 40°F and 70°F. It can survive minimum temperatures down to about 0°F but should be protected from harsh winter winds. This plant does not do well in extremely hot conditions, so during summer it's important to ensure it's not exposed to temperatures consistently above 80°F.

Pruning

Prune the Bell Rhododendron to maintain its shape and remove deadwood, ideally after blooming so as not to cut off next year's buds. Pruning can be done annually, but light trimming is often sufficient. The best time for a more thorough pruning is in the late winter before the plant starts to bud, though light maintenance can be done at any time.

Soil

Rhododendron campylogynum, commonly known as maytenleaf azalea, prefers well-draining acidic soil with a pH ranging from 4.5 to 5.5. The best soil mix for this plant can be made by blending equal parts of peat moss, pine bark, and perlite, which ensures proper drainage and aeration while maintaining the necessary acidity.

Repotting

Maytenleaf azalea should be repotted every 2 to 3 years or when the root system outgrows its container. It's best to repot in the early spring, just before new growth starts, to minimize stress on the plant.

Humidity & Misting

Maytenleaf azalea thrives in high humidity environments; the ideal range is between 60% to 80%. This level of humidity helps A plant to maintain its lush foliage and promotes healthy growth and flowering.

Suitable locations

• Indoor

  Keep maytenleaf azalea near bright, indirect light and maintain high humidity.

• Outdoor

  Plant maytenleaf azalea in dappled sunlight and protect from strong winds.

• Hardiness zone

  7-9 USDA

Life cycle

Rhododendron campylogynum, commonly known as the curve-styled rhododendron, begins its life cycle when the seeds, typically dispersed by wind, germinate in well-draining, acidic soils, often in cool, shaded areas. Seedlings emerge, developing into juvenile plants with characteristically small, leathery leaves and begin photosynthesis to support growth. As the plant matures, it develops a woody stem and forms evergreen shrub-like structures, demonstrating slow to moderate growth rates based on environmental conditions. After reaching maturity, which may take several years, the rhododendron produces bell-shaped flowers that are pollinated by insects, primarily bees, leading to the development of seed capsules. Once pollinated, the flowers give way to seed capsules that, upon maturity, release seeds to initiate the next generation. The curve-styled rhododendron has a perennial lifecycle, with individual plants living for many years and flowering annually, usually from late spring to early summer, depending on climate and location.

Propogation

• Propogation time

  Spring to early summer

• The Rhododendron campylogynum, commonly known as the Bell Rhododendron, is often propagated from semi-hardwood cuttings taken during the late summer. The most popular method involves selecting healthy, non-flowering stems and cutting them into lengths of about 4 to 6 inches (10 to 15 centimeters). Leaves on the lower half of the cutting are removed, and the cut end is dipped into rooting hormone to encourage root development. The prepared cuttings are then placed in a pot filled with a mix of peat and perlite or sand, ensuring good drainage. The pot is covered with a plastic bag or placed in a propagator to maintain high humidity, and kept in a shaded area. Rooting typically occurs in a few weeks, after which the cuttings can be gradually acclimatized to outside conditions before being potted on or planted out.
