As noted, this is a large plot of established mature bamboo that will require specialized equipment and repeated treatments to bring it under control. You might want to consider hiring a local landscaping company to do some of the work for you.
How to kill bamboo using Glyphosate. I was told you cut off each stalk about 8” to 1’ above ground and then use eye dropper to fill the inside tub...
Bamboo is a type of grass so constant mowing with your mower set to its lowest setting will help to keep if from spreading. If you want to get rid of the mature bamboo that is on your property, you will need to cut it back or dig it up and apply an herbicide, and the timing of the cutting and herbicide application is critical.
Should bamboo (not knotweed) be grown in Minnesota? I have a neighbor saying they plan to grow bamboo as a privacy screen between their property and another neighbor’s. Knowing about the invasive noxious weed lookalike, knotweed, the alarm bells immediately went off in my head.
Bamboo plants should be spaced 3-5 feet apart to form a dense screen. The faster spreading types can be planted farther apart if you are willing to wait a little longer for the screen to fill out. If you want an immediate screen, some types can be planted very close together as long as they have some space to spread in width.
Bamboo is very fast growing, so if these are established plants with large root systems already in place, recovery should be quite fast and you will have new, large canes by the summer. (Unlike a small, new plant that first needs to grow a root system before adding much above-the-ground growth).
