Here in Zone 8 of SC, our warmseason varieties of sod are beginning to yawn, drink milk and cookies, and go to bed. The big winter snooze-fest. As Bob Ross might say, our soft little grassy areas are getting quiet for the coming winter. How do you get ready to go to sleep? Do you do jumping jacks just before you lie down to sleep? Drink an 8-hour energy? I bet not.
Well, guess what? The sod grass in your lawn doesn't especially enjoy getting pumped up just before bedtime either. When you apply fertilizer in the fall, you could have just as well given your grass a shot of caffeine. In general, don't apply nitrogen-containing fertilizer after around August 15th in the Upstate of SC or after around September 1st in the Coastal areas of SC. Let's think of nitrogen (the first number on the fertilizer bag: 10-10-10) as a growth encourager. If you encourage growth while the grass would otherwise (and naturally) be preparing to STOP GROWING, your human-ness is really screwing up your sleepy lawn.
Let's start at the beginning. Here in Coastal NC and SC, we can pretty much think of ourselves in a hardiness zone 7 or zone 8... mostly, zone 8. (See these North Carolina and South Carolina plant hardiness zone maps from the USDA.) Sod is categorized under two main types: warm season and cool season. For our zone, the warm season grasses thrive best. Bermuda, St Augustine, Centipede, and Zoysia are the four most popular varieties of warm season turfgrass (sod). SB Turf, Inc. has top quality warm season grass for sale in coastal North and South Carolina. In fact, these are the only types of sod we sell. When winter gets to our area, we do overseed our 419 Bermuda with rye (which is a cool season type of grass), so if you buy our 419 Bermuda sod from around October through March, chances are, it will be overseeded with annual rye.
How do I know which sod is best for my specific yard, though? Well, that, my friends, is an entire other blog post!
Suffice it to say that if you live in plant hardiness zone 7 or zone 8 of North or Carolina, you can narrow your grass decision down to 4 kinds. Again, these are:
