Go for it. Take as much rootball as you can (6' diameter would be good). The rootzone is probably only 12-16" deep. Water it well, and then don't over water it. When new leaves begin emerging, that will be the good sign. Older leaves will probably die off and it will be unhappy for a while. Worst case, the whole plant will die back, but even then you will most likely get some new pups.

Pitangadiego's info is helpful. I took this risk of transplanting my Kru to a more protected area in my garden. It was 10 ft from base of stem to tip of leaves and the pseudostem itself was about 6 ft. I had to take this risk of relocating it because the mother plant died early this year leaving this baby to thrive on. It was on the northside of my yard and the mother plant did not take the cold spell well.

This was about a month ago. I didn't know if it was going to survive. At first, the older leaves started to droop and turn yellowish, but today I went out to check on it and was surprised with the progress it has made (picture attached).

So, I think it should be ok to try, though I'm not so sure whether it would reestablish itself quickly with your forthcoming mild winter. If there's global warming again this year, maybe it will be fine, but as pitangadiego said, worst case scenario, the plant dies back and most likely throws out some pups when the weather gets warmer. Either way, I think it would be better than chopping off your plant now for it may survive transplanting it whole. All the best!

Thanks for the info. My husband and I moved it today. It was about 12-16" deep as you suggested it might be. We took off a few of the bottom leaves and it seems to be doing well today, we'll see what it looks like tomorrow! We were both suprised when we saw a baby behind the main trunk! So if this one does die, hopefully this baby will live or more will come next year. We've mulched it well and are hoping for the best. Thanks for your advice. Bananafan...your tree is doing great!

I think global warning is hotter summers and colder winters.

Get a spade shovel and plug them out. Keep them out of direct sun until you see them recovering. I have transplanted into direct sun and placed a lawn chair to block the direct sun for a couple of weeks. Ones that I have potted, I placed in the shade. I have lost some after transplanting and have had some look almost dead after transplanting and spring back up and do well.
