My location is Bakersfield, Ca. During our summers our temp ranges anywhere from 90-115*. I recently seeded my lawn which is 3500 sqft with riveria bermuda and had very poor results where very little bermuda sprouted and mostly crabgrass grew in. I've decided that there is just too much shade in the lawn where I have two huge trees that are about 90' in height one on the east side of the lawn and the other on the west. So I'm debating on trying out some fescue but my question is would I just be better off waiting until fall to seed it so I don't have to try and compete with the summer heat and crabgrass issues? I plan on doing a total kill again on the lawn to start off fresh. Any help is very much appreciated!
