My dwarf feijoa (Bambina) was struggling mightily in the garden. The bronze beetle just loved eating all the flower heads despite my efforts to stop them. That meant no fruit in summer time as I had planned.
In an effort to save the bush and maybe eat a fruit off it one day I transplanted it to a large pot. It has flourished and lo and behold in the middle of winter there are two flowers blooming with lots of buds waiting to burst forth. No bronze beetles in sight.
