Troubleshooting
Lavender trumpet vine problems — and how to fix them
Lavender trumpet vine (Clytostoma callistegioides) 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.
Spider mites and aphids
The most common pests, especially in warm, dry conditions. Wash off with a strong jet of water or apply insecticidal soap to affected areas. Maintaining good humidity around the plant helps discourage mite infestations.
Invasive spread
This vine grows extremely vigorously and can escape cultivation to become invasive in some subtropical regions. Prune back hard each summer, and consider growing in a large container to limit spread and contain the root system.
Failure to flower
Usually the result of insufficient light, excess nitrogen, or pruning at the wrong time (removing spring flower buds). Ensure the plant receives ample light, avoid high-nitrogen feeds, and prune only after flowering has finished.
