The urea and soluble salts can both be removed by heavy leaching with tap water, but you'll only be preventing damage from the residual reactive fraction of the urine in the soil - most of the damage is done, so that part can't be 'neutralized'.

Saturate the soil and let it rest for a few minutes, then water thoroughly several times so at least the volume of water the container would hold passes through the soil. If you think the soil will remain wet too long, depot the plant & set it on newspaper to draw most or all of the perched water from the soil before you return it to the pot. Wait a couple of weeks before you fertilize. A soluble fertilizer in a 3:1:2 ratio (like MG 24-8-16 and 12-4-8, or Foliage-Pro 9-3-6) are very good choices.

Al is right......but don't leave your plant in the bathroom. It will need more light, unless you have a skylight that is.

Thanks Al, John and Shannon (on the other post). Have rinsed roots off and left in wet paper towel for a couple of days, then repotted and rewatered allowing water to drain all the way thru. Bathroom has 6 light fixtures with the spiral flor. bulbs that I have been leaving on for about 8 to 10 hours a day.At this point, the plant is still green but droopy with some browning out on the edges of some of the leaves. Should I re-rinse or maybe put it outside for a short time (the dog is gone) or leave it alone and hope for the best? Thanks everyone. Bob

... rinsed off, or flushed several times?

Al

Hey Al,
I took the plant out of the pot, threw away the potting soil, put the plant in the tub and washed all the soil off of it, then rinsed the plant off as carefully as possible with the soft spray on the shower head. Then I wrapped the base or root section in a wet paper towel for about two days and then repotted it in a different pot and watered the soil allowing it to drain thru. Now I'm not sure if I've given it too much water or it's still trying to fight off the dog urine. Thanks, Bob

I understand now. You did the right thing, if your soil is something that drains freely. The effects of the N blast & high salt levels aren't reversible - plants aren't like that. The foliage won't repair itself, so you'll need to remove the affected foliage when you think it's appropriated (after the plant is reestablished).

Al

Thanks, Al. I'll keep you posted. (No pun intended.lol) Bob

Hi, I know just how you feel, I don't care for the neighbors dogs over in my yard doing their business..I like dogs and have 2 of my own...I keep mine at home...
just a idea here, I know that a male dogs urine doesn't do damage, but the female dogs will...on the yard and shrubs garden lime is used to neutralize dog urine....could a little lime be but on the plant soil to help????
I'm just guessing maybe someone else would know best...linda

Lime &/or gypsum are often recommended for removing the brown spots in lawns, but neither are very effective and no where near as effective as diluting the urine with water. It's also a poor idea to add lime or gypsum to containers in an attempt to neutralize urine because lime raises pH quickly & can easily cause more than a few growing problems (mainly pH-induced micro-nutrient deficiencies, but others as well) and adding gypsum raises the EC and TDS of soils (makes them salty - just like fertilizers) and can interfere with the uptake of Mg. I think you should stick with just flushing the soil, MT1.

I know it's been 11 years since you posted your comment on dog urine and plants, however, I felt the strong need to educate you on the subject, "I quote" I know that a male dogs urine doesn't do damage, but the female dogs will... First of all what female dog have you ever saw hike it's leg to urinate? 🤔 I think I can answer that for you, the answer would be none, female dogs destroy lawns by urinating on them, " you know the patches of round dead grass" female dogs and puppies urine. Make dogs mark territory by hiking their lemon everything and anything in their yard and sometimes even inside the house, plants are a natural thing for them to do this on. Moral of the story here is ALL DOGS, ALL ANIMALS and yes even HUMAN URINE WILL KILL YOUR LAWN ,SHRUBS, FLOWERS, GARDENS, AND PLANTS! IF YOU have dogs you need to take this into consideration when doing your landscaping, house plants keep off floor where the dog has easy access to them. It's not the dogs fault, Its ours, Good luck, and I meant no harm to anyone, I just wanted to make sure she had wrong information....

When we had a female dog, we kept a watering pitcher full of water to dilute the area of the lawn she peed in. With male dogs it is usually shrubs, annuals, and perennials that get the brunt of the damage. A hose will usually disperse of that too but at what point do you just give up and let a dog be a dog. A fence will keep out stray dogs and keep yours inside the yard.

Lacey Kilgore - we have a female dog whom I have personally seen hike in our yard to urInate. Before her, I would have said only males hike, but I now know, though rare, female dogs will hike, too!
