I am wondering what is the best way to feed houseplants? Does it differ from one type to another? I have tried a few different things. I have done the stakes, the stuff you sprinkle on it, and the liquid types. I know they would grow better with some. When I do use it I get excited, and tend to over do it. Which is why I have been shying away from feeding them lately. Thanks in advance for all of your help!
