Roots are called Culms and they are kind of strange looking.
Use a shovel to dig down against the culms and then lever them up out of the ground.
I don't use any special care with them other than getting them back in the ground in short order.
They have proven themselves out as a hardy addition to my Stuff that Grows in Nevada list.
Books say this variety of bamboo is hardy down to 15 degrees. I think that is a little off.
The bamboo in my yard has seen temperatures down in the sub-zero range.
Water is the only thing that really seems to determine the growth rate. Funny, seems I've heard that before..
|When you dig a trench out, dig it out just a bit deeper than where the culms were before. I have found that it is better to err on a little too deep than too shallow.|
the trench back in with a mixture of 1/3 Gardner's Gold potting soil
and 2/3 sand (native dirt) to about 2 " below surface. I then
1" layer of Gardner's Gold on top of that and then cover
everything with about 2" of Nevada dirt.
Water everything down well. I don't use a foot to tamp the dirt down. The culms are kind of brittle and it is better to use water and the back end of a shovel.
Since it has been a dry winter, I also pressure up the sprinkler systems and give everything else a drink at the same time.
A cautionary word about this type of bamboo: It can easily spread into areas where you don't want it so give a little forethought before planting.
Some people have taken 50 gallon plastic drums, cut them in half and sunk them in the ground to contain bamboo clumping. That is not a bad idea. It also helps with water consumption by confining water to a much smaller area.
Me, I didn't really consider any of that because nothing would grow in the area the bamboo currently is so if it actually survived, it could invade all it wanted.
A little extra water this last year and it quite well invading into areas I didn't want to see it growing.
It will be interesting to see what transpires next spring.
