ive had big problems growing outside with bugs and birds. i went on holiday to southafrica and brought some seeds back with me. of the 14 that sprouted 11 were eaten by birds i now have covered them with bird netting. The bugs have been eating at the leaves so ive been spraying with some insecticide that shouldnt harm the plants but i dont want to spray them too much, and the new leaves that are apearing havent been sprayed and the bugs are attacking. what to do?
