## Questions & Answers

**Q: Amount of t-nex per gallon per 1,000sq ft for common bermuda?**
A: The label says 0.75 fl oz per 1000 sq ft for common bermuda but 0.25 or 0.2 fl oz per 1000 sq ft for other types.

**Q: Can you apply T Nex to new sod?**
A: I’d wait until it’s fully rooted before applying any inputs

**Q: Can this product be used for taller turf? I like to keep my grass 3~4 in.**
A: Yes, I am guessing you have a cool season grass. It does not have the same effect on cool season grasses like it does on warm season grasses. 

On cool season grasses it will slow growth slightly and keep seed pods from growing. 

On warm season grasses it will greatly slow down vertical growth but push horizontal growth and stop seed pods from growing. 

Use only as directed. It is powerfull and could hurt the lawn if not used as directed.

**Q: How long will 128oz last me, using on my entire 15K sqft yard at recommended intervals? Augusta GA Bermuda 1" HOC**
A: Well, I use .25 oz per 1000 sq ft, so you would use 3.75 oz per application for your 15k sq ft yard.  Divide 128 oz by 3.75, which is your oz per use, that would yield you a total of 34 uses per container.
