I was thinking of planting some of these in my yard. I know that they dont stand a chance in my winters here but, i have read that you can treat them like bulb plants and dig them up in the winter, then put them in a frost free basement. I have also read that either i have to cut it down to a 2ft or higher stump, or bring the tree in whole. Other wise i was just going to pot them up and bring them in for the winter. Now regarding their roots. I know that there are many types of root systems, but concidering that these are related to grass, their roots shouldnt go down too deep, they more have a root ball, or a mass of roots correct?? Does any one know how deep tey may get in a season or 2???
