winterizing my jap. maples
Hi all. I havent posted in a while. I have several specimens of Jap. maples.. all in pots.. I have a dwarf, orange katsura, a Tam and a MIKAWA yatsubusa along with a regular maple that my son planted as a todler (came from a helicopter off a tree, now its 5 ft high).. Well all of them are in large pots. Every winter I have wrapped them in burlap and mulched the crowns... have to say,,, getting tired of doing that.. is it completely necessary to wrap them, and if so.. is there anything else I can use besides burlap and mulch.. or, can I just leave them alone. Thanks.
