Troubleshooting
Bower Vine problems — and how to fix them
Bower Vine (Pandorea jasminoides) 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.
Leaf drop in cool winters
May become semi-deciduous or lose leaves when temperatures drop below 10°C (50°F). This is normal dormancy behaviour; reduce watering and avoid fertilising until spring warmth returns.
Spider mites in dry conditions
Fine webbing on undersides of leaves signals spider mite infestation, common in hot, dry, or heated indoor environments. Raise humidity, rinse foliage, and apply neem oil or insecticidal soap.
Failure to flower
Commonly caused by insufficient sun, excess nitrogen, or drought stress during bud set. Ensure at least 4–5 hours of sun, use a high-K fertiliser, and water consistently through spring.
