Troubleshooting
Hoya Wallichii problems — and how to fix them
Hoya Wallichii (Hoya wallichii) 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.
Crispy, browning leaf edges
Its thin leaves are very sensitive to dry air. Raise humidity above 60% with a humidifier or enclosure and keep it away from heating vents.
Leaf drop from drying out
Unlike thick-leaved hoyas it dislikes going bone dry. Keep the mix lightly moist and water before the medium dries out completely.
Fungal spotting in stagnant air
High humidity needs airflow. Run a small fan and water at the soil line so foliage dries promptly.
Mealybugs
Inspect leaf joints regularly. Remove with alcohol swabs and treat with insecticidal soap, repeating weekly until clear.
