i had buffalo grass for first ten years. Residential property built on half acre. Works as advertised: thrives on neglect, including no watering during hot summer months (turns brown) and no fertizing.
Later, we gradually got rid of it. Trees we planted eventually provided too much shade - buffalo grass absolutely does not grow well in anything except full son. And secondly, we got concerned about fire danger. In the summer, with no water (doesn’t need it), it turns nice and dry and brown.
If you have nothing but sun and it will always be full sun, and you don’t mind the fire hazard or it’s such that it’s not a fire hazard, then it’s an exceptional grass for hot climates.
I have one zone that’s still buffalo grass. My Iro2 settings result in much less water for this zone than any of my other zones. Absent rain, in the summer, I go about 4 weeks in between watering.
