I have heard that some members use some tubs with rope handles from Wall Mart. You need to drill some drain hols in the bottom for drainage, and they look nice. Or you can possibly stop by a landscaper or nursery and see if they have any large empty pots. Or you can find a plastic 55 gallon barrel and cut the bottom 1/3 off, trill in some drain holes, and add your rope handles. Big box stores have large planters as well. Just about any large container could be used as long as it DRAINS. Bigger pot, more potting soil, larger plant= heavy. It will be harder to bring in. I have lots of options as far as moving my plants. You do what's right for you. One of those small carts with 4 wheels for moving furniture would work for those big pots. I use my forklift. I hope this helps.
Your plant looks great. The Manzano is on my list for next year. Good luck.
