Troubleshooting
Hoya Sunrise problems — and how to fix them
Hoya Sunrise (Hoya 'Sunrise' (lacunosa x obscura)) 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.
No red colour
Leaves stay plain green in low light; more bright indirect or gentle direct sun triggers the anthocyanin sun-stress flush.
Yellow or mushy leaves
Overwatering or a dense, water-retentive mix causing root rot; let the soil dry more between waterings.
Shrivelled, soft leaves
Underwatering or chronically dry roots; give a thorough soak and drain.
No flowers
Plant too young, too little light, or recently repotted; Hoyas bloom when mature and slightly pot-bound.
Removed flower spurs
Never cut the bare peduncle stubs left after blooming — new flowers form again from the same spur.
Mealybugs and spider mites
Sap-suckers hide in leaf joints, especially in dry air; wipe with diluted alcohol and raise humidity.
