Watch out for

Powdery mildew: Tolerate unless severe; avoid fungicides to protect biodiversity and soil health.

Bud blast: Remove and destroy infected buds promptly if practical for the plant size.

Vine weevil: Use biological nematodes in soil or physical barriers to prevent adult laying eggs.

Silver leaf: Remove affected branches well below the infection site and destroy them immediately.

Rhododendron leafhopper: Encourage natural predators like ladybirds; chemical control is difficult due to their mobility.
