Hoover, unless you are experienced at putting sod down or unless your back yard is flat, smooth and square, it is almost always a good idea to hire someone to do the job for you.

A site has to be prepared properly to receive sod or it won't knit properly and quickly. By hiring professionals, you can specify the variety that you want.

If you do hire a service, be sure to follow all the steps of checking for references, insurance, and that kind of stuff. You still have a little bit of time, so shop around a bit. Zoysia can be planted while still dormant, but does better if the temperatures are going to stay warm.

Just a reminder, though your Zorro can tolerate some shade, all turfgrasses do best when they get plenty of sunlight. You'll need to be careful that you do not over water, over fertilize a shade grown turf.
