What happens to a fig tree with fungus gnats?

When a fig tree is infested with fungus gnats, the larvae feed on the tree's roots, which can lead to root damage and hinder the plant's ability to absorb nutrients and water. This stress may cause the fig tree to exhibit symptoms like wilting, yellowing leaves, and stunted growth. Additionally, the presence of these pests can create an environment conducive to root rot and fungal diseases. Effective management includes improving soil drainage, reducing overwatering, and using biological or chemical controls as needed.
