I think my yard has some type of fungus or dieses. I have a very large tree that has something on the leaves. Some type of fungus/discoloration. I have tried to lay sod 2 times, but each time it dies. First was centipede and the second was St Augustine. The backyard is mostly covered by the tree and the grass dies within a few weeks. The front is not covered, but it dies after a season. In the back I even tried spreading that seed mix that has everything including rye grass and that didn't even take. I had some real thin blade grass sprout then die.
I want to try a soil testing company, but it looks like they only test for PH and Nitrogen. Is there any that test for dieses as well ?
Thanks Jason
