How to Grow Bamboo in Cold Climates

I've written several blog post about the bamboo in my backyard here in Michigan. The 5 links below are some of the past history, starting back in 2009.

Bamboo in Heavy Snow - pictures after a big winter ice storm
Bamboo - 2011 - a much harsher winter meant lots of dead leaves in the spring
More Drain Pipe - trying to route a roof gutter drain around bamboo roots
Bamboo 2 - the first winter, hoping my small trees survive
Bamboo - the original grove of trees in West Virginia where i brought the trees home from

Here are some pictures from the past 4 years:

This was the original grove of trees in West Virginia where i traveled for work and ended up bringing trees home. I believe that they are Yellow Grove Bamboo but that is my non-expert opinion. I also brought home Cane Break Bamboo from Kentucky but it is a lot slower growing in my yard.
This was one of the largest trees i saw there. Probably 2-3" in diameter and at least 40' high.

The first winter after transplanting the bamboo to my yard. As long as the roots don't get below -15 degrees they should survive.

This was created from several pictures of my Moso Bamboo stitched together. I grew the Moso Bamboo from a seed. And like the Cane Break Bamboo, it's a slow grower here in Michigan.

After a winter ice storm my bamboo trees were completely bent over. But i don't think i lost a single one. The trees are really strong and can withstand a lot of stress.

Now, onto this year.

Bamboo shoots coming up March 22nd. About a month earlier than any previous years.

If i'm lucky and the summer last long enough, they might send up shoots a couple of times this year.

The bamboo continued to send up shoots through the early part of April. The warmer the weather the faster they grow.

One thing i'm worried about is that, usually the shoots grow all at once during the first warm month. This year they grew half way, then it got super cold, they stopped growing, then when it warms up they will grow to their full height. I'm not sure how that will affect them.

But there were tons of new shoots and their diameter was slightly thicker than the previous year, which is what i hoped for. Each year more more trees = more leaves = more energy stored in the roots (rhizomes) and that = bigger trees for the next year.
They are also taller then any of the tress from the previous years.

I noticed a lot of bent or broken shoots. I've seen this before and i think it's from ants that chew on the stalks. Sometimes they survive and the stalks have this weird bend in them. But most of the time they fold over and die.

But that damage only happens while they are soft. Once they grow a bit and harden up they can't really be hurt.
