Troubleshooting
Hoya Australis problems — and how to fix them
Hoya Australis (Hoya australis) 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
Overwatering or a poorly draining mix suffocates the roots and causes them to rot.
Mealybugs
White cottony insects cluster in leaf joints and on stems, sucking sap and weakening the plant.
No flowers
Insufficient light is the usual cause; the plant needs bright indirect light to set its flower clusters.
Scorched leaves
Direct, intense sun bleaches or browns the foliage.
Dropped peduncles
Cutting off the old flower spurs (peduncles) removes the points where future blooms form, so they should be left intact.
Wrinkled, soft leaves
Underwatering or, more often, rot-damaged roots that can no longer take up water leave foliage dehydrated.
