fungus gnats on Fiddle Leaf Fig
Quick answer
If your Fiddle Leaf Fig has fungus gnats, the most likely cause is: Larvae of Bradysia spp. thrive in persistently moist, organic-rich soil, pruning fine root hairs which limits the plant's ability to take up water and nutrients, leading to brown spots and drooping.
Start here:
- 1. Deploy yellow sticky traps to capture adult gnats.
- 2. Water with a 1:4 hydrogen peroxide (3%) and water solution to kill larvae on contact.
