How Gypsum Cleans Up Dog Urine Spots in Your Lawn

August 11, 2020 |

If you live in Bergen County, NJ or Rockland County, NY, you know your dog’s urine causes ugly brown spots to appear on your lawn.

While you love your dog, you also care about how your lawn looks. Can you have a green lawn and a dog at the same time?

The answer is yes with gypsum.

Gypsum Defined

What is gypsum?

It’s a rock that’s mined for its calcium sulfate. When your Rockland County lawn service applies gypsum to your soil, you’re getting calcium without changing the pH of the ground.

For dog owners, gypsum works wonders turning those ugly brown spots back to green. Here are some other benefits of gypsum:

  • Gypsum adds minerals to the soil
  • Gypsum gets rid of excess salt in the ground
  • Gypsum reduces compacted soil; it’s a natural soil aerator
  • Gypsum opens up the soil so air and water can penetrate deep
  • Gypsum helps grass roots to develop and grow underground
  • Gypsum helps your grass lawn absorb vital nutrients
  • Gypsum neutralizes uric acid found in dog urine
  • Gypsum helps the grass green up again in areas where your dog urinated

  • Gypsum works faster than lime, so your dog urine stains turn greener faster
  • Gypsum goes into the subsoil where lime can’t reach
  • Gypsum adds calcium to the soil that helps with nutrient absorption and improved moisture intake
  • Gypsum makes the soil happy!

How Does Majestic Lawn Care and Landscape Apply Gypsum to Dog Urine Stains?

When our technicians work on your lawn to clean up dog urine stains, they’ll first take a quick soil sample in that area. The soil test will tell us what nutrients are missing as well as the pH of the soil.

Your dog’s urine causes the brown spots due to the excess nitrogen as well as uric acid. The nitrogen, in your dog’s urine, is caused by the high protein diet that most dogs eat.

When there is too much nitrogen and uric acid, you’ll notice those brown spots developing.

After we see your test results, we’ll use that information to decide how much gypsum to use on your Bergen County, NJ lawn. We recommend that you water your yard after a gypsum application, based on the instructions that we leave for you.

How Long Does It Take for Gypsum to Work Its Magic?

Your grass will green up again in a few weeks up to a few months. While you’re waiting for the gypsum to work its magic, you can designate an area on your Rockland County yard for Fluffy to do his business.

For example, we at Majestic Lawn Care and Landscape, design a space on your property that’s dedicated to your dog’s toilet area. We can add mulch or stones that won’t wilt and go brown from Fluffy’s urine.

We can reseed the damaged areas so you can have a robust green lawn throughout your NJ/NY property.

Conversely, you may be a lucky homeowner whose dog produces greener grass instead of brown spots when it goes to the bathroom.

You may want to have a soil test for other parts of your property to see if these areas need more nitrogen since they’re not as green those areas where your pooch goes potty.

It’s Time for Fall Lawn Aeration and Overseeding

Bergen and Rockland Counties have clay soil. And clay soil makes it difficult for turfgrass roots to develop deep underground. Water and nutrients also have a difficult time absorbing into the ground.

September is the perfect time to aerate your lawn and overseed it. The temperatures are cooling, and the days aren’t as long as we head into fall.

When we aerate your soil, we use a machine called an aerator that takes small plugs of soil out of the ground. These plugs will crumble if you mow over them or dissolve if you turn on your in-ground sprinkler system.

The holes allow oxygen and water into the soil as well as relieve compacted soil. We overseed your lawn after we’re finished with aeration.

If you have brown spots caused by your dog’s urine or you want your lawn aerated in September, call us today at (845) 708-2988 for Rockland County, NY properties, and (201) 788-7191 for Bergen County, NJ properties.
