Hoya Bud Drop: Too Much Sun

Observation

Hoya (likely Hoya bella) produces many buds that wither and fall. Moved from north-facing living room to south-facing sunroom in spring.

Cause

South sunroom likely provides too intense light. Hoyas want bright, indirect light or gentle morning sun only. Bud drop is a classic stress response to excess light/heat.

Fix

Move back to bright, indirect light (east or north window).
Water when top 2 inches dry (current schedule is fine).
Buds should hold and open in proper light.
