Look up the list of plants it kills. I know that it can kill kudzu and bamboo -I've done it personally. I would try mixing 6-8oz per gallon if something like that. **Q: How long should I wait before planting my own garden? I want to kill existing grass and then put in plants of my own.** A: It only kill when it is sprayed on the leaf. Ground deactivates it **Q: Why doesn't this kill anything?** A: I use about 4 oz per gallon of water. Spray and make sure you have a day or two of sunshine. No rain for several days. It takes close to a week to really show the killing power, but believe me it works.
