Troubleshooting
Heart-Leaf Krohniana problems — and how to fix them
Heart-Leaf Krohniana (Hoya krohniana) 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 from overwatering
The most common killer. Yellowing, soft or mushy leaves and a sour, earthy smell from the mix signal waterlogged roots. Let the medium dry more between waterings, ensure drainage, and repot into fresh chunky mix if rot has set in.
Shrivelled, wrinkled leaves
Puckered, soft leaves usually mean underwatering or dehydrated roots (occasionally root damage). Check the rootball; if dry, water thoroughly and the semi-succulent leaves should plump back up.
Sap-sucking pests
Mealybugs, aphids and spider mites can hide in leaf joints and undersides. Wipe down and treat with insecticidal soap or neem oil, repeating every 7-10 days until clear, and isolate affected plants.
Leaf scorch or faded colour
Excessive direct sun bleaches and burns leaves; too little light dulls the silver flecking. Aim for consistent bright indirect light and move it off scorching glass in summer.
No flowers
Often caused by insufficient light, a too-young plant, or accidentally removing the flower spurs. Provide bright indirect light, be patient (2-3 years to bloom), and never cut off the peduncles, which rebloom yearly.
