Preventing and Fixing Dog Urine Spots in Your Lawn and Turf

pug sitting in lawnIf you have dogs, especially large female dogs, then you probably have yellow or dead spots in your lawn created by their urine. It’s worse with female dogs that typically have stronger urine, and also squat in the same spots, but happens with male dogs too. (Life note: male dogs just lift a leg wherever they are at the moment, but the ladies try to remain a bit more organized in their elimination rituals…hmmm?!?!)

Your dog’s urine is highly acidic and can kill the grass it comes in contact with, similar to burning a lawn with over-fertilization. There are products, like dogonit lawn treatment that help to counteract the effects of dog urine on lawns, but if you don’t want to go that route, here are some home remedies for dog urine lawn burn.

4 Ways to Combat Dog Urine Burn in your Lawn

The most common treatment is to saturate the urine spot with water. Enough water has to be used to dilute the urine or even completely wash it away. If you don’t use enough water, you may save the lawn from burning, and instead have lots of very dark green spots where the urine was diluted to the point of actually helping the grass… just not evenly!
This approach to control dog urine problems takes a lot of time and is difficult to get right.

Another way to combat urine burn is to train your dog to do his business in one area of the yard that has been designated as his personal bathroom. It’s a good idea to segregate that spot with river pebbles, sand or even artificial turf. This way, you can clean it up easily. This one shouldn’t be too difficult; afterall, you trained the dog not to pee in the house, and this is just another step along those same lines.

If you like science, another method is to alter the pH of the urine, which can be done by modifying your dog’s diet. Brewers Yeast is found in most dog food, but it’s not at a level that has enough effect on their urine acidity. Some say an additional teaspoonful of Brewers Yeast added to the dog’s daily diet, can reduce the pH of the urine enough to prevent lawn damage. Some folks purchase Brewer’s Yeast in tablet form as well.

In addition to altering the pH or the dog’s urine, you can alter the pH or your soil by adding lime. dog urine burn in lawnIf there are common areas on the lawn that are affected by the dog’s urine, sprinkle them with lime. If you are unsure, you can perform a soil test prior to utilizing lime as a neutralizer.

Just remember, if you can train the dog to go in one central area, the lime idea works well. Many folks have asked me if it is possible to burn your lawn with lime, and the answer is “no” you can’t burn your grass with lime. A 25lb bag of lime is available at Menard’s for $2.98. It’s cheap and works! You just have to stay consistent.

If you already have areas that are damaged, the best bet is to saturate the spots with water, and read this article on seeding barespots in your lawn. Just remember to rake out the dead lawn areas prior to seeding.
You can also try dogonit lawn treatment spray if none of the above seems to be to your liking.

Lime Treatments for Sweet and Sour Lawn Soil

Most homeowners think of their yard in terms of the grass only, but healthy soil is the basis for the green love we call our lawn. With this in mind, you should consider whether your lawn could benefit from an application of lime.

Turf grasses will not grow well in highly acidic soils. Acid conditions in lawn soil can occur due to overuse of nitrogen fertilizers; introduction of excessive amounts of organic soil conditioner, such as compost or peat moss, and by needles dropped from evergreen bushes and trees.
Acidic soils are commonly referred to as “sour,” whereas alkaline soils are called “sweet.” Extremes on either end are not good for turf grass.

Hopefully you remember a little something from 8th grade chemistry and testing pH levels: a really pretty lawn!remember that pH is measured from 1-14, with 7 being neutral?
Just like liquids in the chemistry lab, soil with a reaction of less than pH 7.0 is acidic and soil with a reaction greater than pH 7.0 is alkaline. Most turf grasses grow best between pH 6.5 and pH 7.0. (finicky little buggers those grass blades are!)

So how do you know your soil’s pH?

You can get a kit from one of my fine sponsors if you like. Gardens Alive!
sells a very easy to understand kit for $40. It comes with everything you need and can be used multiple times. Order now for arrival in time for Spring! (once you get to the site, use their search feature in the upper left with key words ‘soil ph’)

What’s lime and can it go in a pie?
Two important elements that help maintain the balance in the soil are calcium and magnesium. (Lime! but not for pies. ;))
Acidic soil is not necessarily useless, but is a sign that the supply of calcium and magnesium is lowand needs replenishing. What’s more, high acidity or low pH levels may also cause other nutrients to be un-usable to grass plants. The greater the acidity of the soil, the greater the need for lime.
Lime is a compound of calcium or calcium and magnesium capable of counteracting the harmful effects of an acid soil on lawn grasses
Functions of Lime
Lime is NOT a fertilizer, but more of a soil amendment or conditioner. Here’s what it helps with:

  • Corrects soil acidity (obviously!)
  • Furnishes important plant nutrients-calcium and magnesium (redundant right?)
  • Promotes availability and use of major plant nutrients and micro nutrients. It’s like greasing a wheel… it just makes things run through more smoothly.
  • It increases bacterial activity in the soil which promotes more air exchange, thus aerating the root system. (It’s all microbial and stuff like that!)

soil test kit from Gardens AliveTime of Application
To obtain maximum results, the best time to apply lime to the lawn is when the soil is being prepared for planting. Too late for you and me right?
Applications of lime on existing lawnsare best applied in Fall and Spring because of cooler temperatures and readily available moisture. Pelletized lime is available at most garden stores or Home Depot, and you can use your normal broadcast spreader to apply it evenly across your lawn. –you can also get it from Gardens Alive!

You should follow the directions on the bagged product you purchase, however, I’d recommend a double pass underneath evergreen trees and shrubs as these areas are highly acidic from these acid-loving plants. Be sure to use your testing kit again about 3 weeks after the application to see if you have any improvement. If not, re-apply.

Finally, too much lime can be as damaging to lawn grasses as the lack of it. Lime is not a “magic bullet” for all lawn problems but is an essential fundamental step for soil health and the overall health of your turf.
