Troubleshooting
Orange Clock Vine problems — and how to fix them
Orange Clock Vine (Thunbergia gregorii) 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.
Aphids
Congregate on young shoot tips; remove with a strong water jet or insecticidal soap spray.
Spider mites
Increase humidity and use neem oil or insecticidal soap at first signs of stippling on leaves.
Root rot
Avoid overwatering and ensure drainage holes are unobstructed in containers.
Sparse flowering
Usually caused by insufficient light or excess nitrogen; move to a sunnier spot and use a high-potassium feed.
Frost damage
Frost-tender; bring containers indoors before the first frost or treat as an annual in cool-temperate climates.
