I was given this beautiful cactus two years ago. It has been sitting in the same spot since. It sits in a bright, for the most part non direct sunlight. I water weekly, however; haven't fertilized until recently. The stems have turned a reddish purple color. I fertilized the first time in a long while (my bad) last week. I watered today from bottom like always and plant doesn't seem to be soaking it up. I also notice little hair looking things (roots) coming up out of watering hole in pot, which I believe means the cactus is root, or pot bound. With this being mid September would it be wise to repot? Will the reddish purple stems turn back green since I fertilized? Any help would be much appreciated! This was given to me by a dear friend and I'm sure it has been around a long time. Thank you!!
