Hi everyone! Hope everyone’s having a sunny afternoon! I had a question for everyone; What do you do to prevent fungus gnats on newly bought plants/or how do you tackle them when they are already there?

Everytime you water? Thanks so much for the comment! (:

Definitely the first time after you bring a plant home, and if you see gnats. I mix the nematode powder with my fertilizer water, so the plants get it about every other watering.
