## Questions & Answers

**Q: How long after seeding (ttfescue, perennial rye, kbg) and applying fertilizer should i wait before using extreme lawn booster?**
A: I applied after 2 mows. So I'd say about a month

**Q: Is this concentrated? If so, how many gallons of water do you add?**
A: It is concentrated and you don't dilute it, the spray bottle system delivers the right amount with your hose water pressure (if it works well). Should take 30-40 minutes to apply.

**Q: will this kill my new seed  they have not sprouted yet?**
A: No, it won't kill your new seed -- in fact it will help establish them. All of the Simple Solution products do not burn and are in concentrations that are beneficial in virtually all cases. I have used most of them for a few years and they seem to be the best lawn products i have found.

**Q: I killed/scalped/detached weed-infested lawn and plan to slice-seed new tttf tall fescue. when before/after seeding should i apply this? (san diego)**
A: Apply after seeds have sprouted. Best if sprayed with a  sprayer that you can pre mix the water then spray.
