Need some help. My mom's got a half acre lot in an old neighborhood. Has St Augustine lawn with two massive legacy oaks in the backyard and multiple oaks in the front. There are landscaping beds all around the entire property.
I go out today to look at her lawn and notice that the st aug is dying back from the perimeter of every inch of the yard. If there is a fence, a flowerbed border, a tree, etc - any "boundary" within the entire lawn there is no grass around. It almost looks like someone walked the entire perimeter of the yard with glyphosate and put it down heavy 3ft off the entire fenceline but I know for a fact that's not happening because they don't have a lawn service, pest control service, and my dad doesn't use anything like that in the lawn ever.
In the middle of the lawn - the grass is actually pretty healthy and they keep it properly irrigated so it's growing pretty well still this late into the year. I'll update the thread with pics - but imagine a perfect 1-2ft border of dirt around the entire property line with healthy grass growing right up to the edge of it.
