First post over here in the organic section, please be kind. To start, I am not licensed to apply any sort of pesticide in my state. I'm not going to do the applying myself of any information i receive here. I am interested in getting information for one of my customers who, to make a long short, has a very good reason to be completely terrified of any chemicals at all. With that said, she has a paver walkway that is becoming quickly overgrown with grass and weeds that she does not want to be there at all. Also, she is now beginning to get a very bad case of poison ivy in her back yard, climbing both a large oak tree and her privacy fence. Any suggestions to either kill or at least stunt the growth of either of these issues would be greatly appreciated. *as an aside, I have read on here on several occasions that high concentrate vinegar works similar to glysophate. is this true, and where would one go about finding that product?
