Troubleshooting
Chinese Honeysuckle problems — and how to fix them
Chinese Honeysuckle (Combretum indicum) 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.
Poor or no flowering
Primarily caused by insufficient direct sunlight or excess nitrogen feeding. Ensure the vine receives at least 6 hours of direct sun and switch to a low-nitrogen, high-potassium fertiliser in summer. Hard pruning after flowering encourages a fresh flush of flower-bearing lateral shoots.
Invasive spreading via root suckers
Produces vigorous underground runners that send up new suckers around the base. Sever suckers at root level promptly. In warm humid climates the plant can become invasive; root barriers help contain spread in garden beds. Listed as potentially invasive in Florida and parts of the Pacific.
Spider mites in dry conditions
Dry conditions and low humidity encourage spider mite outbreaks; look for fine webbing and stippled, pale leaves. Increase humidity, spray foliage with water in the morning, and treat with neem oil or insecticidal soap targeting the undersides of leaves.
