drooping
GR-8115Cause
Chronic overwatering in low-light Nordic winters leads to basal stem necrosis and root death. Succulent rhizomes rot in dense soil when transpiration slows.
Solutions
- Downsize to a pot 1/2 current size to keep roots tight and promote faster drying.
- Amend soil with 40-50% perlite or pumice for superior aeration and drainage.
- Wait to water until rhizomes begin to wrinkle slightly (usually 2-3 times total between late fall and early spring).
Prevention
Supplement low natural light with full-spectrum LEDs (12-14 hours/day) in high-latitude regions.

GR-8113Cause
ZZ plants are marketed as 'low light,' but extreme low light (<500 foot-candles) leads to reduced photosynthesis, yellowing (chlorosis), and etiolation.
Solutions
- Relocate to bright indirect light (near an east/west window).
- Verify soil is dry before watering to rule out concurrent root rot.
- Trim yellow leaves to redirect energy to the rhizome.
Prevention
Position in consistent medium indirect light; use grow lights if the room has no windows.
