I just recived a japanese red maple bonsai. it was covered in a plastic for shipping so i removed the plastic and let it sit outside. After a few days it was giving a few more leaves but then kind of slowed down and just died, i thought it would regrow new leaves but no. I let it sit outside a few more days just to be sure but it was just dead for sure. It always had water but never dried out, i don't know if it was probably too hot, since i live in florida, which is why i kept it under an umbrella, does anyone know why, so i can prevent it from happing again? Please help?
