Well I'm certain that the rabbits are responsible for the damage on the edges, they would sit on the pressure treated wood border I made and chomp away until there was nothing left.RockyMtnLawnNut said:It's interesting that you mention the rabbits. I have an area in my front yard that looks exactly like the last picture. The rabbits were munching on the grass and took it all the way down to the crown. I couldn't tell if I noticed rabbit droppings in that picture or not, but they were present in the area of my lawn that looked like that.vanawesome said:The burned areas oddly enough appeared after my first application of milorganite. I just tried the screw drive test and seems clear. One small rock (smaller than a ping pong ball.)
No dogs in the area. But I do have a lot of rabbits. I have been killing them with an air rifle and giving them to my friend who eats rabbit. I thought maybe they were nests, but no baby rabbits found.
Ah ha!!!LIgrass said:maybe Gray Leaf Spot? http://www.turffiles.ncsu.edu/diseases/gray-leaf-spot
PRG is very susceptible to GLS.
Totally makes sense now why this acts up after putting down milorganite which is high in nitrogen. This has to be what it is. Thanks!! Guess I'll back off from using any more Milo until after several more fungicide applications.Any factor that increases the amount of leaf wetness will increase gray leaf spot development such as extended periods of cloud cover, improper irrigation timing/frequency, or extended rainfall events. Lush leaf tissue produced by turf that is fertilized with excessive nitrogen is extremely prone to infection by the gray leaf spot pathogen.
