Troubleshooting
Hoya Micrantha problems — and how to fix them
Hoya Micrantha (Hoya micrantha) 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.
Yellowing, mushy leaves
A sign of overwatering or a mix that holds too much water. Let the medium dry further between waterings and confirm the pot drains freely.
Failure to bloom
Usually too little light. Move to a brighter spot and avoid removing the old flower spurs (peduncles), as new umbels form on the same stubs year after year.
Sticky leaves or cottony pests
Mealybugs and aphids are drawn to fresh growth and nectar. Wipe with diluted insecticidal soap or 70% isopropyl alcohol on a cotton swab, repeating weekly until clear.
Fungal leaf spotting
Water lingering on the slightly fuzzy leaves can cause dark spots. Water at the soil line, improve airflow, and avoid overhead misting.
