how do I stop the brown spots on my lawn?

Question

I have tried numerous types of pesticide type products, no real improvement

Answer 1

do you have a dog? or could someone elses dog be using your yard?? that can cause brown spots to appear.

Answer 2

No one can really tell you what the spots may be. My first guess would be brown patch. It is a disease caused by a lack of nutrients and excessive water. This disease occurs this time of year on zoysia and st augustine grasses or many cool season grasses. Magnesium and less water can get rid of it. However, the spots could be a result of mower damage, over watering, underwatering, poor nutrients, dog pee, and more. My recommendation would be to try less water if you don't think heat stress is the problem, but if this is not the case, then I would ask a professional.

Answer 3

You must have St. Augustine.
Nothing you can buy over the counter will work worth a crap.
Cleary 336 fungicide is ok.
Compass fungicide is the real deal. Apply as a liquid at 2.5 gal per minute. Mix ratio is 3/4 oz per gallon.
Follow up with second app 7 to 10 days apart.
DO NOT FERTILIZE or your yard will be history.
Call Scotts Lawn Service. They are nation wide and can solve the problem. (I work for them!!!)

Answer 4

The brown spots may be caused by a neighbors dog. If you have lift the sod to check if you have grubs and there are none. Then the next best guess would be a dog peeing on you lawn.

Answer 5

Sounds like a fungal problem. Are the brown spots moister underneath than the other grass? Does it keep happening in the same areas or does it move? Do you only get it when its warm and humid?

Wash the bottom of your mower after mowing(wheels too) as they will spread fungal spores.

Try using a product like mancozeb, copper oxychloride, fungarid or some other fungicide and see if it stops the areas spreading

Answer 6

It may be an animal "relieving" himself on your lawn: raccoon, skunk, dogs, cats....personally, I just let my lawn go for a couple of weeks (don't mow it) and it gets really green and lush; when I mow, no brown spots....this "quirky" habit drives my neighbor (we call him Hank Hill) nuts since he's out on his little 10x20 patch of grass at least twice a week, cutting, pulling weeds, mulching, fertilizing, liming; I've actually seen him on his knees with scissors trying to make the grass "even"...talk about obsessive/compulsive...

Answer 7

try watering your grass at night time or early morning
and dont cut it too short the sun will kill it.
i had the same problem i had a weed man come in and i went with what they told me, and my grass has never in the 10 years look so good i was very impressed but they also sprayed weed killers and grass seed as well. let it go for a period of time before cutting it.
good luck hope all the brown gets out

Answer 8

got a dog? females are the worst - that would be your starting point (get rid of the dog)

Answer 9
