Tellmann's honeysuckle problems — and how to fix them
Tellmann's honeysuckle (Lonicera x tellmanniana) 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
The most common issue, especially in warm, dry summers or crowded positions. Water consistently, mulch deeply, and ensure good air circulation around stems. Apply sulphur-based fungicide at first sign. Mildew is worse where roots dry out.
Aphid infestation
Honeysuckle aphids cluster on new shoot tips causing distortion. Treat promptly with insecticidal soap or a strong jet of water. In established gardens, natural predators usually keep populations in check without chemical intervention.
Failure to flower
Often a position problem — insufficient light reaching the canopy, or roots that are too dry. Ensure the stems receive adequate sun and mulch the root zone heavily. Newly planted specimens may need two to three seasons to produce a strong display.
