I live and work in San Diego county, most types of grass grow here. I tried it on all types, Don't like it won't ever use it again. It takes way to long for green-up, one lawn I had to put it on three times before it greened up. Plus it smells like cat piss! I have a great fert i'v been using for 28 years and I will keep with it. Bests turf supreme in the summer and bests nitro king in the winter. My dealer talked me in to buying some fert from Norway once. After I bought it I was driving away asking my self, What the hell did I just do?! I bought fert from Norway? They don't know what kind pf soil we have in San Diego! Plus why in the hell am I helping the Norwegian economy?
