Troubleshooting
Flat-Leaf Wax Plant problems — and how to fix them
Flat-Leaf Wax Plant (Hoya planifolia) 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.
Root rot
Standing moisture in a heavy or compacted mix causes root rot, particularly through winter. Use a coarse epiphytic blend and ensure the pot drains freely after every watering.
Scale insects
Brown, limpet-like scale can colonise stems and the undersides of the flat leaves. Scrape off manually, then treat with horticultural oil or systemic insecticide if the infestation is established.
Leaf yellowing
Yellow leaves most often signal overwatering or a draughty position near a window in cold weather. Let the mix dry more thoroughly and move the plant away from cold air currents.
