I have this "crop circle" that popped up in my yard and I don't know what it is. I suspect this is where my septic is...Does anyone know what it could be caused by?

It's perfectly round and perfectly BROWN. The ground is firm where this is...not mushy or anything. Actually, other than being brown, its just like the surrounding area...It happened about 3 weeks ago.

huh, well aside from the obvious alien visit, did someone dump something out right there, antifreeze, weed killer i say this because somehting along those line happend to us,

Could you have one of those round septic tanks buried under there? I've seen this before in summer where the grass goes brown over the exact shape of the tank.

My thought was the tank - but do you think that means there is something wrong with it? I googled "brown circle in my lawn" and got a few grub stories...I'll have to check that out when I get home.

I don't think its from a spill....nothing that I know of anyway.

Aliens are a distinct possiblity....

It looks in the picture that the grass is a little longer and greener below the circle, away from the house. Could that be the drain field? Do you have a septic tank and if so do you know where it is?

Aliens would be cool, though.

I do have a septic tank and its out there somewhere - what I wonder is if its the tank - does that mean there is a problem with the tank or just the grass reacting to it?? I know you guys probably aren't lawn experts, but just bouncing things off you....

"aaaaaaah", says Yoda.

To me, it looks like it might be a lawn fungus... crops up when we have very humid and hot summers. It could also be an insect problem. Go to Home Depot and buy a fertilizer with insecticide and also a fungicide application. Some places can diagnosis the problem from a soil sample for free.

if the grass pulls up easily dig around and see if you have grub worms and ck on garden web forum for advice

I checked for grubs - nothing...The grass is firmly in the ground. I think it just must be from the septic. I told my DH to deal with it!

I feel for you. Septic problems of any kind are not fun.

When was the last time you had your septic tank cleaned? It may very well be the septic. We had our plumbing back up last year (our septic was just cleaned the year b4) and got very worried that we were looking at a new leach bed. Trust me, you don't want to replace a leach bed.....we're talking major bucks. Luckily, it was our D-box going into the leach bed that needed replaced. It was actually crumbling. I think it was under $700 for all, can't exactly remember.

Good luck and let us know what you find out.

I'll ask my hubby when he gets home, but I'm betting it's septic tank related. Call your local spetic tank folks and ask...it may be time to dig up the lid and pump it out? ewwww. Good luck!

I might suggest that you check and see if the ground is dry under the dead grass. I have seen this too before. Here in the NW. I get cranefly. I take a bucket of soapy water and pour it on the brown area. I continue to water heavily and if green appears it may of solved your problem. Also if you have had very warm weather it may be that the tank it is creating heat and burning the grass. ( perhaps not down deep enough) Have you ever seen this before? Good Luck. DeAnn
