Can anyone tell me how best to keep my house plants from getting out of control? I have a Yukka in a 40cm pot which now has roots coming through the bottom and also a dragon plant and a money plant (?) that are outgrowing their pots and the space I have for them. I read that you can prune the roots, but am scared of damaging the plants. I could repot the yukka, but am struggling to find a nice indoor plant pot that is large enough- any recommendations of where to buy one would be appreciated. Many thanks.
