Have had several years, when it got bigger a few years ago, I just kept a small pup. I just up potted that pup into about a 10 inch black pot and found two spiraling offshoots trapped down below. So I think I will get a couple more pups now that those are freed and directed to the surface.
Aug 2023, here I am again taking pups off the main one. Have a very nice one in a 6 inch clay pot from spring.
