Troubleshooting
Hoya Blashernaezii problems — and how to fix them
Hoya Blashernaezii (Hoya blashernaezii) 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.
Sparse flowering in low light
Despite being a willing bloomer, it needs bright indirect light to flower freely. Move it brighter and never cut off the bare flower spurs, which produce new blooms each cycle.
Root rot from overwatering
The semi-succulent leaves mean it stores water and dislikes constant moisture. Let the mix dry partway between waterings and use an airy, free-draining medium to keep roots healthy.
Sticky residue and sooty mould
Flowers drip sweet nectar that can leave sticky droplets; this is normal, but the same sugars attract ants and can host sooty mould. Wipe affected leaves and watch for sap-sucking pests.
Mealybugs and aphids
Drawn to the abundant flowers and new growth. Inspect peduncles and leaf joints regularly and treat early with insecticidal soap or dilute isopropyl alcohol.
