Troubleshooting
Hoya Erythrina problems — and how to fix them
Hoya Erythrina (Hoya erythrina) 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.
Loss of red colour in low light
The prized red veining and margins fade to plain green without enough light. Move to brighter indirect light, with a little filtered sun, to bring the colour back; lean watering also helps.
Root rot from overwatering
Semi-succulent leaves mean it stores water and dislikes wet feet. Use an airy, free-draining mix, let it dry partway between waterings, and water sparingly in winter.
Leaf scorch from harsh sun
While it loves light, direct midday summer sun can burn the leaves and cause bleached patches. Use bright but filtered light, especially during the hottest months.
Mealybugs and aphids
Sweet flowers and new growth attract sap-suckers that hide at nodes and on buds. Inspect regularly and treat early with insecticidal soap or dilute isopropyl alcohol.
