Hello! I need help with my cactus here. I have had it for at least 2 years now, and when I got it there were flowers on it and it looked good! Then I had someone else repot it who was supposed to know how to, and it has not grown much since then. I tried reporting it myself a few months back (and I was shocked to see that there was nothing really there for roots, maybe 3/4 of an inch. I didn’t know if that was normal or not so I just put it in new soil in the same pot and back in the window), but there was still no progress with it growing or having flowers on it. Unfortunately, it recently got caught on the curtain and fell out of the pot, which allowed me to see that there were hardly any roots still. And still not looking healthy I don’t think, and no flowers, but I don’t know anything about this plant. It also keeps leaning no mater how many times I try to center it, which I assume is because it has no roots? Help please!
