I had my entire yard sodded with Zoysia Ultimate in October 2010. It never seemed to establish well in some areas. Now it is September 2011 and it seems like the whole yard is dying. It has rained about 8 inches in August. The soil is sandy and well irrigated. I suspect fungus. I live in a restricted deed neighborhood and am afraid the HOA will get on me; plus I am broke. :-) Help.
