Dwayne gave good advice. You may also inquire what your neighbors are
growing. Maybe you had the wrong seed. Sodding is a quick method but
again, it will take constant attention to keep it damp during dry hot
days. The most important is to have the right seed or sod. Stores here,
Houston TX., sell tons of seed not suitable for this clime!
Note, Water in the morning, grass doesn't grow after dark.
