Troubleshooting
Wonga Wonga Vine problems — and how to fix them
Wonga Wonga Vine (Pandorea pandorana) 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.
Invasive vigour
Can become very vigorous and smother smaller plants or damage guttering if left unpruned. Prune hard after flowering each year to keep within bounds and maintain a tidy framework.
Powdery mildew
May appear in humid climates with poor airflow. Improve air circulation by thinning congested growth and apply a copper-based or sulfur-based fungicide at first signs.
Scale insects
Soft or armoured scale can colonise stems, causing yellowing and weakening. Treat with horticultural oil spray in cooler months, ensuring full coverage of stems and leaf undersides.
