Rhododendron impeditum

dwarf rhododendron

Product Image
Masses of broadly funnel-shaped, purplish-blue flowers cover this evergreen shrub in mid- and late spring, putting on a really impressive display. The foliage is small and grey-green, and when bruised gently it is aromatic.

Rhododendron impeditum forms a compact low mound that makes it particularly good for patio pots, larger rock gardens, or front of border positions.

How to care for Rhododendron impeditum:

When planting, avoid planting too deeply, and incorporate well-rotted compost or manure into the planting hole, adding some mycorrhizal fungi to aid root establishment. Rhododendrons prefer an acid soil or ericaceous compost that is well-draining.

Remove spent flower heads regularly to encourage prolonged flowering. In late autumn, after flowering has finished, cut back any dead or damaged growth to maintain a tidy shape. In early spring, prune lightly to remove any winter-damaged stems and to promote strong, healthy new growth.

Apply a generous 5-7cm (2-3in) mulch of leaf mould around the base of the plant each spring. Protect from strong winter winds.
