Title: Comparison of native turf with St. Augustine and Kentucky bluegrass
Answered by: Nan Hampton and Mark Simmons
You are correct that the Native Lawns study didn't do comparisons with St. Augustine and Kentucky bluegrass. This is because it has already been established that they do not resist drought as well as buffalograss and Bermudagrass. You can see comparisons that include St. Augustine and zoysia grass in a study, Non-irrigated Turfgrass Study, by J. A. McAfee and Ron Leps for the Williamson County Extension Service.
Another factor that affects the success of turf grass is the amount of sunlight. The native lawns study was a full sun study so we cannot draw conclusions about shade conditions from that study. It is known, however, that the turf grasses of the study, especially Bouteloua dactyloides (Buffalograss), don't fare as well in shade as St. Augustine. Additionally, buffalograss doesn't grow well in sand, a common soil type in the Houston area.
We can conclude that buffalograss and/or the multi-species native turf that includes buffalograss does very well in the sun with little irrigation once it has been established. Please read Native Lawns: Buffalograss and Native Lawns: Multi-species for more information.
You can read the answer to a recent question to find native grass substitutes for shady sites in the Houston area.
