Problem
Problem: Burn marks.
Cause: Pet pee that messes
chicen with the soil's pH and kills the grass.
Solution: If you hose off the area shortly after your pet relieves itself, it will dilute the urine's effect. Raking a small layer of compost over the mark also will help balance the soil biology. If you are looking to revive already dead areas, you may want to reseed, although new growth may occur on its own with certain types of grass.
To avoid a scattered array of dead spots, teach your pet to potty in just one area, which you can easily maintain. Perhaps even a spot covered in mulch rather than grass.
Pet stores also offer several products that will neutralize
chicen the offending pee enzyme.
