*What is the USDA zone in your area?
*How tall do you want your ground cover to grow?
*Is there much foot traffic from humans or animals in this part of the yard?
*Do you plan on mowing the groundcover, and if so how high?
*Finally; what kind of grass is growing and does well in the rest of the yard?

1. Which Zone? South - Midwest region - 5b
2. How tall? About 3 to 4 inches should do.
3. Is there foot traffic? Very little to none
4. Do I plan to mow? If mowing is required, I'll mow.
5. What kind of grass currently grows in my yard? Generally the yard is sunny and tall fescue grows throughout the yard very well, except were heavily shaded under these oaks.
Thanks.....
