scale on Hoya Finlaysonii P
Quick answer
If your Hoya Finlaysonii P has scale, the most likely cause is: The same Hoya genus profile that lists mealybugs also flags scale as a recurring pest, because scale insects settle on the stems and undersides of leaves near the midrib, looking like small brown bumps that hide a soft body beneath a hard shell as they feed on the sap of the thick-leaved vine.
Start here:
- 1. Wipe the armored shell of each scale insect with a cotton swab drenched in isopropyl alcohol, making sure to penetrate the shell so the alcohol reaches the soft insect body underneath, and rub off the bumps with a soft toothbrush before washing the leaf with mild soapy water.
- 2. Spray the entire vine with All Seasons Horticultural Oil or insecticidal soap after the manual removal, repeating the applications on a schedule because scale is difficult to eliminate and the shell protects the insect from a single treatment.

Keep scale off this Hoya Finlaysonii P
Quarantine new Hoya plants for several weeks before placing them near other houseplants, inspect the stems and leaf undersides whenever you water, and keep the plant well-spaced so air circulates freely around the waxy leaves, since scale tends to colonize vines that sit in still, warm indoor air.
