sooby said:Keith, when you say the spots get worse and worse every year do you mean that individual ones get bigger? That wouldn't likely be animals in that case. How big are the spots and are they circular or irregular?
porkpal said:That is what the grass looks like over out septic tank which has a round lid a few inches under the turf. The shallow soil can't hold enough water to keep the grass alive and green. Do you have a septic system?

Meaning they start with grass dying, slowly less grass is in the area, and eventually no grass is left just bare soil. The spots are irregular and I dug and saw no grubs or anything, the rest of the lawn is lush and green.
greene said:Just jumping in for a minute. Keith, I realize you have sewers, but has the property every had a septic system in the past? I lived in a house that originally had a septic system; after the city installed sewer lines we hooked up to the new system but the old septic tank was still in place with the lid (as @porkpal mentioned) was just a few inches under the soil.
Use a piece of re-bar and jab it into the soil where the bare spot is and see if you contact anything hard like metal or concrete.
Okay, I'll go back to lurking now.

Keith, did you also do the check for chinch bugs? If you could post a picture showing the spots and the surrounding area it may help. I think this thread has got a little confused with the OP's pictures of large round patches and your zoysia problem. Maybe it would be a good idea to start a separate thread?

They are the same symptoms. Here are photos of mine, a semi damaged spot and a very bad one.
porkpal said:Do the spots recover and new ones appear or are they chronic?
sooby said:
The symptoms don't look the same to me. Gotsqueeze's patches are circular, which makes them less likely to be caused by an insect pest whereas your patches are irregular which could be a number of things. We need to see more of the larger environment but if you'd rather not post a picture that may be identifying of your location then can you tell us if this grass is walked on (the second picture patch is somewhat elongated and looks compacted but can't see how long the elongation is - rather looks like foot traffic), if it is near a road (salt injury), whether irrigated, fertilized, any tree roots etc. etc.
One thing you could do if you don't think the problem is somehow environmental is take a watering can with two or three tablespoons of dishwashing liquid in a couple of gallons of water and pour some of it on the turf around the bare spots. You don't need to pour all of it on but just enough to soak in to a couple of square feet or so. Wait about five minutes and then see if any insects come out. This is a hands and knees job! If you don't know what the insects are (they aren't necessarily all bad) then try and get a picture of them so we can check them out. You'll need to flush the area you tested with plain water afterwards to dilute the soap so that it doesn't add to the damage.
greene said:We seem to have two threads here. This is confusing my brain.
Can we split this into two; one for the original poster gotsqueeze and a separate thread for Keith?
sooby said:Keith, what is the bowl for?
keithp2012 said:
Food and water for my cats
greene said: gotsqueeze started this thread to ask about spots on his lawn.
Somehow we are now talking about Keith and his cat's water bowls.
Can we get back on topic please?
sooby said:
Are the bowls always in the same place?
