The blooms will need to be protect from damaging late frosts.

Rhododendron impeditum will be happy in a sheltered position in full sun to semi-shade. The soil should be acidic humus rich, reliably moist but well-drained moist. Avoid planting too deeply, and if necessary dig plenty of ericaceous compost into the soil before planting.

 Apply a generous mulch of leaf mould around the base of the plant each spring maintain soil moisture and stable soil temperatures over the summer.

Rhododendron impeditum received the Award of Merit from the Royal Horticultural Society in 1944 and the Award of Garden Merit in 1984.
