I was able to get my neighbor to have a long row of spreading bamboo removed from the borderline of our property. I was advised by a realtor to file a complaint at city hall as its illegal to grow bamboo in our city. I decided not to go that route and spoke with the owner instead. He was willing to have it removed once I showed him that it had grown out of control and was spreading on to my property along with causing a lot of leaf litter as well. So, here we are a few weeks later, bamboo removed, but I have noticed sprouts rising from under ground. The landscaper who did the job advised me to keep on top of it as that will happen. I`ve been using Spectracide spray now and then but the sprouts continue to appear. Is there a better more effective spray to use to kill them off roots and all? I`ve been trying to dig them out (under gravel) but that is quite a chore. Any further suggestions is well appreciated. Thank you
