Hi. I'm a newbie. I've been growing houseplants for about five or six years now, but I'm starting to learn (finally) that just watering them and feeding them from time to time isn't going to keep some of my older and more beloved plants going. I've been reading a lot here and in other places for advice, and I want to thank you guys for all I've learned from you.
Here's my question: does anyone have a link, or can give instruction, on exactly *how* to prune roots? I've read that it's necessary on some plants and why, but I don't want to try anything without knowing exactly how it's done.
