Moved into a home in a rural area. No lawn.

Went to a local equipment rental facility that also sold sod grass by the
pallet. Looked at his list of species and the traits of some 5 different
species of St. Augustine. Picked out the type indicating high tolerance to
heat and drought. They brought out a couple of truckloads of topsoil to put
around the house first. Then I laid the sod. This was in April.

Have kept the grass irrigated, and did some light watering in the late
evening to supplement when appeared the heat was drying the grass out.

The back of the house is what I expected due to the prevailing shaded area
near the house. Lush and green. Some other areas are having difficulty
maintaining their green-ness. Guess due to the heat, and when the rain is
less prevalent.

Have noticed in the sunny areas, there are some single sods if you will,
that are deep green and seem unaffected by the heat. These are few, the
remaining seem to dry up and start turning yellow.

Did the sod contractor (not the reseller) mix up the grass species in the
order?
