Hi, just wanted to share some photos of the cacti I repotted 4 years ago now. They are now 9 years old and the tallest is about 80cm and the fattest about 5cm at the widest. I ended up repotting them, burying the bottom 10cm of original growth. I went slow with the sunlight and water that first summer, then the next year moved them outside and they really took off and started springing out pups for the first time. What a pain to repot, especially having 5 cacti in one pot originally, having to untangle a big mess of roots! I squeezed the big one a little too hard when I was trying to hold it upright in the new pot and you can see the markings. They are just coming out of winter hibernation and the big one is still a bit droopy.
