Etruscan honeysuckle problems — and how to fix them
Etruscan honeysuckle (Lonicera etrusca) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
A common problem in dry spells or on plants with poor air circulation. Maintain adequate soil moisture, mulch the root zone, and if necessary apply a sulphur-based fungicide. Choose resistant cultivars such as 'Superba' where mildew is recurrent.
Honeysuckle aphids
Sap-sucking aphids cluster on young shoot tips, causing distortion and leaf curl. Treat with insecticidal soap or encourage natural predators such as ladybirds and lacewings. Severe infestations can be pruned out.
Sparse flowering
Usually caused by too much shade or excessive nitrogen. Relocate to a sunnier position, prune out congested old wood after flowering, and switch to a high-potassium feed to promote blooms over foliage.
