Using vinegar to kill bamboo
I brought a house a year ago with a 4' by 10' foot patch of land with Bamboo. As you can guess, that first year was filled with discovery of the invasive nature of the plant. I don't think the previous owner did anything other than pulling out new shoots. I pulled out all the roots I can that exceeded its patch, but a good number is already intertwined with the surrounding bushes.
However, the bamboo creates a spectacular view. I'm thinking about saving a few rhizomes, killing the patch, installing a barrier, and then replanting it. I understand that it'll be years in the future.
So far, my battle plan is as follows:
1. Cut off all shoots and dig out as much rhizomes as I can.
2. Soak the patch area in vinegar. Though, I can't find a place to purchase any of the brand that was recommended yet.
3. Repeat until a year go by without new growth.
Here's my questions:
1. Would the bamboo absorb the vinegar, killing the rhizomes that had grown beyond the patch? I want to avoid applying vinegar outside the area as it is filled with bushes and other plants.
2. There's approximately a 2 feet of soil between the bamboo patch and the bushes. Would the vinegar pose a danger to the bush if apply liberally to the bamboo patch?
3. How long would it takes to make the area plant-able again after applying the vinegar?
