Is this a good time for laying sod in BR?

Don't think it's to early. Might not be exact time of year. Check with your local nursery about your area.

For that size you do want to lay sod. Seed is good for patch jobs, but sod is what you're going to want.

Where there is sun should be fine. My backyard has finally come back after those days of 75 plus degrees days.

Thanks. Any idea how much for 500 sqft?

This site is pretty cool for calculating: Sod Calc

I'd use it as a base then call a few places to find the best price.

Make sure you don't buy the cheapest. I know from experience.
