yellowing leaves on Monstera Adansonii
Quick answer
If your Monstera Adansonii has yellowing leaves, the most likely cause is: Yellow leaves in Monstera adansonii indicate environmental stress with three primary etiologies: (1) Overwatering-induced root hypoxia—soil saturation >7 days creates anaerobic conditions (<2mg/L dissolved oxygen) leading to bacterial root rot, (2) Underwatering—soil bone-dry for 10+ days causes cellular dehydration and chlorophyll degradation, (3) Light stress—direct sun exposure causes photooxidative damage, insufficient light (<500 lux) triggers etiolation yellowing. Sap-sucking pests (thrips, spider mites) also cause mottled chlorosis.
Start here:
- 1. Check soil moisture: insert finger 3 inches deep—if wet with yellowing, reduce watering frequency to 7-14 days
- 2. If dry: water thoroughly until drainage; adjust schedule based on season
