fungus gnats on Zz Plant
Quick answer
If your Zz Plant has fungus gnats, the most likely cause is: Fungus gnats are attracted to moist organic matter on the soil surface. In ZZ plants, their presence is a critical warning sign that the top soil is not drying out fast enough, which precedes root rot.
Start here:
- 1. Drying out: Let the soil dry completely to kill larvae.
- 2. Bottom-water: Stop top-watering to keep the surface soil dry.
