Troubleshooting
Glandular Rosularia problems — and how to fix them
Glandular Rosularia (Rosularia adenotricha) 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.
Glandular surface collects debris and encourages mould
The sticky leaf hairs trap dust, organic matter, and moisture, providing a substrate for mould in humid conditions. Gently remove debris with a dry brush and ensure excellent air circulation.
Root rot in moisture-retentive soil
Poorly drained compost is the chief cause of plant loss. Repot into fresh, gritty substrate at the first sign of wilting combined with soft, mushy roots.
Vine weevil
Larvae chew roots from below, causing sudden wilting. Inspect roots when repotting; apply nematode-based biological control (Steinernema kraussei) in spring and autumn.
