I'm having an issue (among others) with my St Augustine lawn and flowerbed. I'm in zone 9A and this is happening in the sunniest part of the lawn, most gets sun from 8-9 am to 4-5 pm. I'm about ready to call someone to come in and help get this under control but wanted your opinions first to see if this is something I can take care of on my own. I'm fairly certain this came in when I brought some dirt in to level my yard in a few spots. Any help identifying this would be greatly appreciated.
I'm fairly certain we're going to pull all the mulch and plants up, put down landscaping fabric then remulch.

Thanks in advance!
