Can you tell any difference between that patch and bamboo in full sun? Is it as dense of a grove as one that gets more sun, for example?
@PatapscoMike do you know what species of bamboo you have growing at the back of your yard?
That makes me wonder about using a silage tarp to kill it. I wonder if it would poke through a tarp or whether it would poke through a tarp if first reduced to grass form growth.
Here’s a photo of some bamboo growing at a friend’s house about 20 miles from me. He has multiple different species of mature bamboo. This photo is of Ph. vivax aureocaulis. It’s bigger than it might look at first. Most of the culms are probably 3-4" in diameter. If you look closely you can see some daffodils for scale just to the left of the base of the bamboo grove. I first saw this little grove of bamboo about 7 years ago, and I haven’t noticed any change over the last 7 years. He says shoots don’t come up in his gravel driveway (on the right in the photo) and he says he just kicks over any shoots in the spring during shooting season (when they’re tender and easy to break) that come up in areas he doesn’t want them. He sure seems to make bamboo seem easier to maintain than other very trustworthy accounts. I wonder if the apparent differences are related to differences between species, if some species of running bamboo are just a lot easier to keep in check than others. This same friend has another grove of this same bamboo that he’s let spread over about a full acre, and he describes it as a species that sizes up and forms a mature grove very quickly, but maybe that doesn’t necessarily mean it’s hard to control. He also has a grove of moso and madake (very large timber bamboos, even a little bigger than the bamboo in this photo) that he has let expand as much as possible, but although they’re very tall (60’+) and large they haven’t expanded to anywhere close to an acre in the same time. (He said they were planted at the same time, but I don’t remember if he said how long ago that’s been.)
