I live in Dallas, Texas and we've been having some pretty crazy heat this year.

I try to water my lawn 3 to 4 times a week so my grass doesn't all die. My lawn is doing pretty well considering how dry it's been here, but I have been noticing these really large cracks in different places that are due to the dryness.

My friend said that his lawn does that pretty much every year and they will eventually fill in once it starts raining again.

I'm wondering if there is anything I can do to either prevent or lessen the cracking in my lawn. Also, could these cracks potentially cause a foundation issue?
