Carol, epsom salts plus fertilizer are you saying? My friend used to throw regular water softner salt on weeds to kill them. I guess I am thinking epsom salts could harm them. How much do you use? do you mix it with water ? I am trying to get some two year old Aimee Gardenia plants ready to go to the Market and I am wondering if I should cut them now since they are done blooming and give them a good doze of fertilizer and maybe epsom salt....what do you think? Wow, I am full of questions today. Thanks in advance.
