We had bamboo in our yard and it is extremely hard to erradicate. I have used this directlly on new shoots. I clip them and then paint the chemical onto the shoot with a paint brush. So far so good. Its seems to be killing them. If anyone has any other suggestions, please let me know.
I followed the instructions as to what amounts to add to a gallon a water. I started off with 3 - 4%. It had no affect on the grass between the expansion joints. So I doubled the percentage and tried again. This time it killed the grass & weeds. So far, very little growth came back.
Well this is good stuff, but it is NOT great. It kills broadleaf weeds very fast, but other weeds take almost three weeks to a month with weekly applications. Take nut-sedge for instance. Ironically, the genuine, premixed Round-Up I purchased works like four times faster and in one (1) application. I even mixed this stuff up a little bit stronger than the I was supposed to. The reason I give it four (4) stars is that it does, indeed work on everything if you can wait it out, and that is ultimately what counts.
