Watch out for

Powdery mildew: Mulch in spring to reduce water stress and improve air circulation around the base.

Honeysuckle aphids: Encourage natural predators like ladybirds or use a strong jet of water to dislodge them.

Silver leaf: Prune out affected branches well below the infection point and burn them immediately.

Fungal leaf spot: Remove fallen leaves in autumn to reduce overwintering spores and avoid wetting foliage when watering.

Thrips: Use blue sticky traps to monitor populations and apply horticultural oil if infestations are severe.
