Well, never rototill. I say that all the time, but it is assumed the writer does not have a tractor based rototiller. If you have a tractor to hold the depth exactly at a set point, then rototill away. I know...people are falling out of their chairs reading this, because I'm Mr No-Rototill. Tractors provide a stable platform that will not get tossed around by hard spots underground and will not dig in at the soft spots.

But why are you renovating this time of year? Where do you live? What kind of grass do you want to grow?

The tiller comes with the tractor, it's 5 ft across mounted to the 3 point hitch. I'm located in willacoochee georgia, maybe 2hrs from the Florida line. I called my local extension office and they recommended I use 15 lbs of tiff blair centipede per acre, as long as I have it seeded before July 15th.

Before you buy seed, talk to some nurserymen to see if they know of TifBlair installations that you can go look at. If you feel the need to spend time on your lawn, centipede may not be your cup of tea. It needs light fertilizer once every other year, almost no water, and low mowing. When you start doing stuff to it, it can thin out. Also it only grows in full sun and does not recover quickly from damage. Does that sound like what you want?

I really don't want a high maintenance lawn, reason being is I'm away from home a lot for work. The only other seed I have looked into in the tiff Blair zoysia "zenith" but the soil requirements are a ph of 6 to 7 and after my soil test I'm at a 5.7 would the zoysia work??

Centipede loves acid soil, that's the direction I'd go. Zoysia can be fine when all is right with the world, but once it goes bad, it's bad for a long time.
