Sun Stressing on hoya
What's Happening
Environmental shifts causing roots to take up water faster than leaves can transpire it, leading to blister-like lesions or corky spots (oedema) that resemble sunburn.
How to Fix It
- 1
Stabilize watering schedule and allow top 2-3 inches of soil to dry between waterings
- 2
Improve airflow around the plant to aid transpiration
- 3
Do not trim affected leaves unless desired for aesthetics; oedema is harmless
How to Prevent It
Avoid erratic watering and ensure the plant is not subjected to sudden drops in temperature or spikes in humidity.
