I am having a gnat problem. So far am using vinegar with soap to attract them away from my bonsais, also kills them. Am letting the plants get drier. All my bonsais are indoor. Gnats dislike several different essential oils. Has anyone tried using diluted essential oils as a lite spray on the top soil layer. I don't have a tree that I can risk trying this on. Anyone have a tree to try it on? How do other growers keep the gnats away?
Thank you, Can send solution mix if one member might want to try this.
