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.

American Lotus

A few months ago i was working down at the coal burning Consumers Energy power plant near the Michigan-Ohio border. They are actually just north of North Maumee Bay and use the lakes water for cooling.
There's lots of weeds, cattails and other plants in the protected cove. The power plant also has a huge net and "fish trap" to keep their pipes clear of debris. One day i saw thousands and thousands of little 4" fish, shad i think, that had completely filled the hanging metal basket.

In September i was there and in the bay there were these huge lillypads, they looked to be 3 feet in diameter. You can see that they took up half the channel.
I took this picture with my cell phone. In early November, that month the fog seemed to stay there every morning.

Later in the year around November, all of the lillypads were gone and these brown, round floating things with seeds in them were in their place...and lots of trash because it's Lake Erie.
At the time i wasn't sure exactly what they were but i liked them and brought home a handful of seeds. I found out later that the plant and seed pod were from the American Lotus.

I then read that:

• It's the only native lotus species to the U.S. and Canada

• Native Americans used to eat the seeds and rhizomes (roots)

• The plant is a good "indicator" species and only grows in clean water. They also like the warmer waters around places like power plant discharge pipes. Turns out that the Consumer Energy power plant is actually one of the places that Monroe's Lotus Garden Club (how much do i NOT want to hang out with that group) visits each year.

• Lillypads can be 1ft - 3ft in diameter

• The white and yellow flower can be 10" in diameter

• In Michigan it is listed as a "threatened" plant, it's "endangered" in some states, and Connecticut has it on their "invasive plant list" because of it's ability to crowd out other plant species. I can see why from this picture taken somewhere down south.

I also learned that lotus seeds have special enzymes, which allow them to last for hundreds and even thousands of years. In Tokyo they found seeds that were buried deep in mud and carbon dating showed that they were over 2,000 years old. The scientists planted them and they grew.

The only trick is that lotus seeds need to have their shell scarified, or roughened up. If the outer shell is not rubbed or cracked in some way nothing will happen.

So here's a few of the seeds i found.
Here's what they looked like after i filed through the outer shell.
I tried growing them in 2 different ways. The first was by placing them in a wet paper towel then putting that in a plastic zip-lock bag. I laid the bag over a heat vent to get it nice and warm.

The second way was to simply drop them in a cup of warm water. You can see two of the seeds floated and probably won't grow.
We'll see how they turn out. After two days i haven't seen any change.
