About Nova Zembla Rhododendron
Botanically, Rhododendron 'Nova Zembla' is a moderate-growing shrub in the Ericaceae family. It reaches around 3 m tall and 2.5 m wide at maturity, with evergreen foliage. Red flowers appear in spring.
Where to grow Nova Zembla Rhododendron
Nova Zembla Rhododendron suits cool-temperate climates and grows best in part shade or morning sun and shade and low-light positions. It is frost hardy and shrugs off cold winters.
Soil & planting
Nova Zembla Rhododendron does best in acidic and free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool. For a screen, space plants about 1.5 m apart.
Watering & feeding
Nova Zembla Rhododendron prefers consistently moist soil. A light spring feed is usually enough to maintain steady growth. Check moisture below the mulch during establishment and water thoroughly when needed rather than following a rigid schedule.
Pruning & care
Prune Nova Zembla Rhododendron after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. Expect a moderate maintenance care workload once it is established.
Using Nova Zembla Rhododendron in the garden
Nova Zembla Rhododendron earns its place for a feature or specimen planting, a fast screen or informal hedge and pots and courtyard containers. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For easier irrigation and care, group Nova Zembla Rhododendron with species that also favour consistently moist soil and cool-temperate climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
Note that it is toxic to cats and dogs, so site it away from pets that chew. All parts can be toxic if eaten, so keep it away from small children.
