I have a prop that the cust wants me to remove some heavenly blue morning glories, that have been there for a couple years, reseeding the whole time. The job is fairly easy to make pleasing to the eye, but that crap is going to come back if I don t get every damn shoot out or killed. So there is a spa and the deck is about 2 feet off the ground, does anyone know a way to 'scorch the earth' under the deck, and not effect the surrounding flowerbeds? There's not much foliage on the shoots under there, so I'm not too sure about spraying RU. How would you do it?
