Let me start off by saying I do not have moso but... I think you are in a climate that warrants at least trying to grow it. It will probably take leaf damage in the single digits(F), and suffer die-back to below the mulch(or snow) line when it dips below 0. Luckily it should send up new shoots in spring so long as the temperature does not go below -20F. Adding tons of mulch would help to keep the moso warm in extreme cold. As for size, well it would most likely be much less than half of its mature height. Maybe after a long number of years it would grow a bit larger, but it will never get to be as large as moso grown in South Carolina.

I betcha it dies. Especially if you don't mulch or you don't get much snow cover.

If you're going to try Moso, get the Anderson clone which is a bit hardier (7-a).

In order to mulch, would you cut the stalks to the ground and then throw mulch on top?

Don't cut anything till spring, then cut anything dead. cover as much of the plant you can with straw. if you can, put a wire fence around plant and fill with straw. Good luck, this is the first year for mine in the ground too.

I'm going to try next year from seeds.

I have about 10 1-2' canes in a 14" pot inside with good air circulation. So far so good. I'm hoping to keep it potted for a year or 2, letting it become a bit larger and extensive before planting outside.
