I feed my cham a lot of bsfl, I also feed the adult Soldier flies. When I replaced the plant I took the old plant/ pot outside and dumped it out. The dirt was loaded with bsfl, hundreds of them. There was evidence the bsfl ate the roots of the plant, which I'm sure killed it. Who said bsfl are hard to propagate . I think I need to cover my new palm with a screen instead of river stone.
