Can I prune a Desert Star cactus?
I bought the cactus at an estate sale...it has really long thin branches with green leaves at the ends ( researching I found this is from not enough light) How much can I prune it, and when? Also, it is potted in a regular pot rather than a shallow dish planter. Can I cut off the long roots and plant it properly?
