Expert tips
The key tip
This less hardy rhododendron needs a temperate microclimate with summer shade and protection from cold winds. Plant it at the foot of a large tree or against a sheltered wall.
The common mistake
Too much summer sun damages the foliage and reduces flowering: people forget that -8°C hardiness also means sensitivity to excessive sunlight.
The pro's trick
Boost winter protection in cold regions with a windbreak screen in November-December.
Care
Light
Rhododendron megeratum prefers partial shade, protected from direct afternoon sun. A spot under tall trees or on the east side of a structure is ideal. Too intense light can scorch the foliage and reduce flowering.
Watering
Keep the soil moist but well-drained during the growing season. Rhododendrons hate dry roots and waterlogged conditions. Water regularly in spring and summer, then reduce in autumn and winter.
Soil and planting
This rhododendron requires acidic, organic-rich and well-drained soil. Amend the soil with ericaceous compost or leaf mold if necessary. Avoid chalky or compacted soils at all costs.
Fertilizer
Apply a gentle fertilizer for acid-loving plants in spring, after flowering. Moderate feeding is sufficient; rhododendrons are not heavy feeders. Avoid excess nitrogen, which reduces flowering.
Pruning and maintenance
Pruning is not essential, but pinching back young shoots after flowering encourages branching. Remove spent flowers to promote better flowering the following year and direct the plant's energy.
Diseases and pests
Susceptible to stagnant moisture which can cause rot. Watch for powdery mildew in warm, humid conditions. Spider mites may appear in overly dry environments; increase air humidity if necessary.
Did you know?
Rhododendron megeratum is part of the rich Himalayan flora and has attractive grey-blue evergreen foliage that remains ornamental year-round. Its botanical name 'megeratum' literally means 'with large foliage', referring to its persistent leaves of fine size that generously clothe the shrub.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
