|We have a little lap dog and we are getting little yellow spots where he is peeing in the grass... is there anything to fix this, or do i need to dig it up and replant seeds?|
|Dog urine contains concentrations of salts, so it has probably thrown the soil pH off a little. I suggest raking about an inch of compost into the area. The compost contains soil organisms that can help balance to the soil biology and chemistry. Depending on the grass species, new blades may sprout in the renovated area, but you can always put down a little seed to get it going again. If your dog 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 fix the dead spots, but it's difficult to avoid having dead spots due to pet urine. The salts in urine kill off the grass so you'll need to flood the spots to leach out the salts, then rake out the dead grass and over-seed with new grass seed. The seed should germinate in 7-10 days. As for keeping new dead areas from forming, about the only course of action is to hose the area off as soon as your pet urinates. This will dilute the urine and keep it from killing the grass. Some pet stores sell dietary supplements that are supposed to neutralize the urine. You might check into those. Wish I had a better solution for you!
