Please help me and my tree! I have a 40+ year-old Ficus that I received as a gift in December. It keeps getting spidermite attacks. I have sprayed twice now with GardenSafe insecticide and the little buggers are still coming back. If I keep spraying it, will it start to damage the tree? Should I consider repotting it now, since I don't know when the last time it was repotted was?
Thank you in advance!
