Re: Cutting off pups and the dead leaves in preparation for over-wintering
They don't really seem that hard to over-winter once you've done it. I just like to wrap the stem up very well so moisture doesn't get in, and I have pretty much an endless supply of trash bags from the hundreds of leaf bags that have been collected for leaf mulch.
This time around, I plan on using 3ft tall fencing, with bamboo sticks to keep it upright, and fill it up with tree leaves so that the whole thing is well insulated. If it doesn't protect all of the stem, there's still a foot of corm under the ground so I'm not that concerned, plus they survived last winter with ease.
