My lawn is a beautifull green bermuda. Except for these brown rings that keep popping up. What are they and what can I do? They can range from size but are generally about 30″ in diameter.

I-villeIt sounds like you have spring dead spot disease. It is caused by a fungus in the soil.The dead spots will shrink and fill in later in the summer. One cultural practice is the disturb the soil in the dead spots with a pitch fork or spade fork to disrupt the fungal growth since it is very fragile.If you want to start all over, there are several bermudgrass pedigrees that have good tollerance to SDS.
