dropping leaves on Hoya
Quick answer
If your Hoya has dropping leaves, the most likely cause is: Leaf drop in Hoyas typically indicates acute stress rather than chronic issues. Common triggers include: (1) Sudden temperature drops below 60�F (15�C) or cold drafts from windows/doors, (2) Severe underwatering causing emergency leaf abscission to conserve resources, (3) Root rot reaching critical stage where roots can no longer support foliage, (4) Pest infestations (spider mites, mealybugs) causing leaf desiccation, (5) Transplant shock from recent repotting, (6) Over-fertilization causing salt burn and root damage. Hoyas will sacrifice leaves to preserve the vine/stem when under extreme stress.
Start here:
- 1. Immediately assess environment: Check for cold drafts, recent temperature changes, or heating/AC vents nearby. Move to stable 65-80�F location
- 2. Check soil moisture: If bone dry, water thoroughly; if wet, unpot and inspect for root rot

How to reverse dropping leaves on Hoya
- 1
Immediately assess environment: Check for cold drafts, recent temperature changes, or heating/AC vents nearby. Move to stable 65-80�F location
- 2
Check soil moisture: If bone dry, water thoroughly; if wet, unpot and inspect for root rot
- 3
Inspect undersides of remaining leaves and stems with magnification for pests (webbing, cottony masses, tiny moving dots)
- 4
If recent repotting: Maintain high humidity (60-70%), avoid direct sun, and do not fertilize for 4-6 weeks
- 5
Remove dropped leaves promptly to prevent fungal growth and pest attraction
- 6
If leaf drop continues, take stem cuttings with 2-3 nodes as insurance propagation�Hoyas root readily even from stressed plants
Keep dropping leaves off this Hoya
Maintain stable temperatures year-round; avoid placing Hoyas near exterior doors, drafty windows, or HVAC vents. Water before leaves show extreme stress. Quarantine new plants. Use consistent, weak fertilization (1/4 strength) rather than sporadic heavy feeding. Acclimate gradually to any environmental changes.
