|We have brown patches in our yard from our dogs.|
It just keeps spreading and getting worse any solutions, besides getting rid of the dogs.
|Dog urine is alkaline and contains concentrations of salts, so it has problably thrown the soil pH off a little. I suggests raking about an inch of compost into the area. The compost contains soil organisms that can help balance to the soil biology and chemistry. If your dogs usually uses your lawn for relief, douse the area with a hose to dilute the effect of the urine soon after the fact. Consider also giving the dog his/her own area and fencing it in while you enjoy the rest of the lawn. You can rake and reseed in the spring or autumn months when the weather is cooler. Some of the sturdier grasses for growth in your area include Bermuda and Kentucky Bluegrass.|
