I kill plants; it's a known fact. I have an aloe, a cactus, and a philodendron, all known hardy survivors of even the worst gardener. And the philodendron struggles. A couple of months ago, I was given the dying-est of all houseplants, a miniature rose. I usually manage to kill these before they even leave my office, and this one looked no different - it was brown around the edges on the way home. But I cut it all the way back to the dirt, and watered it regularly (I know, I know, you're supposed to do that), and today I am proud to report that it's busting out in bloom! Ta da!
