✂️ Prune

Viburnum scale: Tolerate light infestations to encourage natural predators; manually remove severe colonies or replace heavily infested plants.

Aphids: Encourage natural predators like ladybirds and lacewings, or treat with insecticidal soap if populations are high.

Powdery mildew: Improve air circulation by pruning, water at the base to keep foliage dry, and apply a fungicide if necessary.

Viburnum beetle: Hand-pick adult beetles into soapy water; severe cases may require insecticidal control.

Weather damage: Ensure well-drained soil, mulch to retain moisture in dry spells, and protect young plants from harsh frosts.
