Here's what I did year before last with 10-11 hybrid lilies, and all survived. Doing as Bill C had previously suggested worked well. The link that RAH posted shows it, and I may try the burlap liner next. It should make it much easier to remove the root ball when transplanting.
Here's some pics of my original effort. Not sure how they'll flow, but here goes.
The first pic is of a tuber I'm splitting for 3 pots. Each tuber had at least 2 leaves. The second pic should be the 3 planting stages I took. Tuber in the planter's mix, pond clay added to top, then covered in river rock. 3rd pic is a bucket that had a hole in the bottom. It took one season for the rhizomes to start crawling out.
