✂️ Care

After flowering, remove spent blooms to encourage denser branching and abundant flowering the following year. Apply a thick organic mulch at the base to retain soil moisture and protect shallow roots. Water regularly during the first two years to develop a deep and robust root system.

Once well-established, 'Northern Hi-Lights' rhododendron requires little maintenance and tolerates harsh winters well. Avoid alkaline soils and overly sunny exposures, which can damage the foliage. Prune lightly after flowering to maintain a compact and harmonious silhouette.
