You can certainlymix the two if you wish,but you may not like the results. My experience has been that St Augustine,even Bitter Blue which is promoted as having very good shade tolerance,is only marginally better than Centipede under trees.

Is Centipede grass a good choice for a lawn?
I鈥檝e had lawns with both Centipede and St. Augustine and in the southern states, they each do really well. I鈥檝e become partial to centipede over the last decade mainly because it is a lower growing grass that does not require mowing with the same frequency as St. Augustine.
Will St Augustine spread over Centipede grass?
Augustine will spread it鈥檚 runners wide and begin spreading into the Centipede but if the Centipede grass is healthy, it鈥檒l grow into the St. Augustine grass just as aggressively. I have test areas in my yard where I planted St. Augustine over two years ago and those patches are still pretty much contained by the surrounding centipede.
How do you care for Centipede grass?
Centipede is more cold tolerant than St. Augustine grasses but has less shade tolerance. It requires at least 6 hours of sunlight each day to prevent it from dying. Even though it is aggressive, it is still easily contained as it only produces surface runners which are easily contained by bed liners.
Where does Centipede grass grow in the US?
Both centipede, and St Augustine grass, grow in similar regions. Using the United States Department of Agriculture, (USDA) zoning, centipede grows best in zones 7-10, and St Augustine, zones 8-10. These grasses grow in central, southern, and some coastal regions.
