Hoya Pubicalyx 'Red Buttons' problems — and how to fix them
Hoya Pubicalyx 'Red Buttons' (Hoya pubicalyx 'Red Buttons') 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.
Overwatering and root rot
The main risk. Yellow, mushy leaves signal sodden roots; let the airy mix dry well between waterings and use a pot with drainage. This species would rather be dry than wet.
Sparse flowering
Too little light or removing flower spurs. Give bright indirect light, keep it slightly pot-bound, feed before bloom season, and never cut off the bare flower peduncles.
Sticky sap on flowers
The blooms drip nectar that can stain surfaces below. This is normal, not a problem; simply place it where dripping nectar won't damage furniture or floors.
Mealybugs and aphids
Pests target new growth and flower buds. Inspect often and treat with insecticidal soap or alcohol, repeating to break the breeding cycle.
