We noticed a crap ton of termites and ants on my wood raised planter bed full of romaine and weeds for my sully, Ralph. I sprayed with peppermint, orange, tea tree, and citronella essential oils mixed with water. The weeds have not sprouted yet and the romaine just started sprouting last week. I mainly sprayed the outside of the box, but inevitably spray got in the dirt and on the sprouts. Will the weeds and romaine be safe for Ralph?
