Why is dog pee harmful to vegetation?
“There are three primary reasons why dog urine burns grass: alkaline urine pH, the concentration of the urine, and its nitrogen load.” – 3 Reasons Your Dog’s Urine Kills Your Grass
“One of the primary components in dog urine that affects shrubs and other plants is urea, a type of nitrogen waste that is produced as the body metabolizes protein. Because dogs have a large protein requirement in their diets, a significant amount of urea can be produced by a healthy dog. When a dog pees on your shrubs, the urea in the urine acts as a source of nitrogen for the plant and the surrounding soil.
Nitrogen is an essential element for plant development, and in small amounts the nitrogen provided by dog urine can actually benefit your shrubs.
While shrubs need nitrogen for proper growth and development, too much nitrogen can be detrimental; it can stunt or potentially even kill the shrub.” – Will Dog Pee Kill Shrubs?
How to prevent dog pee from damaging your plants
– Protect your plants
While fencing your garden off is a bit of a harsh way to keep your dog out, raised flower beds are just as effective and have other practical benefits.
– Train your dog not to pee on the grass
“Provide an area in your yard, away from your garden, consisting of sand and soil covered in mulch or pebbles, where your dog can urinate without harming any of your plants or lawn. Plant salt-resistant greenery and grasses near this potty spot, in case it has any accidents. These plants are typically found along the coast and are more urine-resistant than other flora.” – Does Dog Pee Hurt Plants?
– Steer away from (distressed looking) plants and trees
“Of course, a dog’s gotta go when a dog’s gotta go. But when you have the option, steer Fido to a lamppost rather than a tree and a bark covered area rather than a stressed-looking lawn. You can spot stressed trees by bark that is discolored or even peeling off around the base. And trees that are under six inches in diameter or have thin bark are at higher risk.” – Why Does Dog Pee Kill Plants?
– Keep the pH in balance
“For the health of both your dog and your lawn, you should strive to keep your pet’s urine pH right around 6.5, and no higher than 7.
I recommend buying pH strips from your vet or at the local drug store to check your pet’s urine pH at home so you know when it’s in or outside the desired range. In the morning prior to feeding your dog is when you should collect the urine sample. You can either hold the pH tape in the stream of urine while your dog is voiding, or you can catch a urine sample in a container and dip the tape into the sample to check the pH.” – 3 Reasons Your Dog’s Urine Kills Your Grass
How to help your plants recover from dog pee
– Neutralise the soil
“You will need to neutralize the acid fairly quickly or your vegetables will not survive – my father’s trick was to use a few tablespoons of baking soda in a watering can and water the area.” – Is Dog Urine Bad for My Vegetable Garden?
“Sprinkling lime or gypsum in the affected area speeds up the recovery of existing grass, or new growth if you’ve reseeded, by neutralizing the acidity of the affected area.” – Gardening 101: How to have your dog and keep your garden, too!
– Dilute the urine
“After your dog urinates on any plants in your yard, douse the area with water from your garden hose. A thorough rinsing of the area within eight hours of urination dilutes the urine enough to prevent damage to the plant, according to VeterinaryPartner.com. Don’t wait more than 12 hours to rinse the plants because this could actually increase the damage to the plant. Provide your dog with plenty of water to drink, which dilutes the urine even before it winds up in your garden.” – Does Dog Pee Hurt Plants?
– Treat dog urine as fertiliser
If you fertilise your lawn, take into account the overfertilisation your dog can provide and avoid fertilising these areas on top of it.
– Consider plants that like dog wee
“Selecting plants that can survive getting drenched in dog urine is a good idea around your property perimeter. Violas, columbine, lilac, ornamental grasses and a host of other plants are virtually urine proof. Make sure the border plants are not poisonous to dogs.” – How to Stop Dogs From Urinating on Plants
“Clover is highly resistant to pet urine and helps maintain a uniformly green lawn.” – Benefits of a Clover Lawn
– Grow a back-up lawn
“With a little planning, you can easily grow small “turf repair” pots in your back garden. All you need is a small plastic flower pot (3 inch is fine), fill it with some soil, either compost or garden soil, then sow a few grass seeds in the top. Give it a good water and leave it outside somewhere keeping it moist over the next week or so. When your dog has burnt a section of lawn, simply dig out the circle, drop your lawn repair pot grass into the hole and hey presto … fixed! You can set up a number of these pots next to your shed and the grass will sit happily in the pot until needed.” – Dog urine patches killing your lawn?
