## Questions & Answers

**Q: will this work for Spotted spurge**
A: Call RM18 mfg for specific advice

**Q: Will it work on catails and if so though the root?**
A: I'm not sure. 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. Been using this product for years.
