How Hydrated Lime Naturally Removes Pet Odor and Stains from Grass

As pet owners, we all love our furry friends, but sometimes they can cause a bit of a mess that can be difficult to deal with. Dog urine, for example, can leave an unpleasant odor on your lawn and can even damage the grass. Maintaining a healthy lawn is a significant investment in both time and money, and pet urine can cause many problems for grass. Thankfully, there is a simple solution to this problem – lime, which is commonly used in construction, can help eliminate pet odors and maintain healthy grass. Lime works by restoring a healthy pH level to your soil, helping your grass recover and stay healthy, while also neutralizing any odors.

Lime is an alkaline product made from limestone, and because the high levels of nitrogen in pet urine are acidic, lime balances out the pH levels, which helps with odor control and the health of your grass. Hydrated lime works the best for this purpose and has historically been used for odor control. Lime not only covers up the smell but also destroys the pathogens that cause the odor, making it a safe alternative to other chemicals. The best part is that it won’t harm your lawn or your furry friend. Adding lime to your lawn will help you keep a green, lush turf while also eliminating pet urine odors.

How to use lime to banish pet urine odors from your lawn

Hydrated lime is most effective for odor control and purification. Furthermore, hydrated lime works so well because it helps to alkalinize acidic soils, and urine is naturally acidic since it is high in nitrogen. It is often used in agriculture, environmental purification, and the garden to help balance acidity. Additionally, it acts much quicker than other kinds of lime. However, beware that lime can be very potent, so it can have adverse effects if used in excess.

The best way to use lime to eliminate urine odors is to apply a good amount to the affected area. After you sprinkle the lime in the odorous area, be sure to water the area well. You should immediately notice the difference. Be sure to give the area in question a good soak, as this will help the lime seep into the soil and spread the nitrogen out -– helping other areas of your grass to grow. For large-scale applications, it’s recommended to use no more than 50 pounds per 1,000 square feet. However, for small-scale treatment that is usually a concentrated area, you can start with a small amount. After some time passes, gauge how much you need to add, if any. This is a great natural way to keep your lawn green and, most importantly, neutralize those pesky pet urine odors.
