Troubleshooting
Sky Flower Vine problems — and how to fix them
Sky Flower Vine (Thunbergia grandiflora) 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
Especially problematic in dry conditions; increase humidity, mist regularly, and treat with neem oil.
Mealybugs
White cottony clusters at leaf axils; dab with a cotton bud dipped in rubbing alcohol or use insecticidal soap.
Root rot
Caused by poor drainage or overwatering; ensure free-draining soil and ease up on watering if roots smell musty.
Invasive spread
Listed as invasive in parts of Queensland (Australia) and other tropical regions; contain root spread and remove seed pods before dispersal.
Failure to flower
Often linked to insufficient sunlight; relocate to full sun and reduce nitrogen feeding.
