Anyone have a solution to my son's English Bulldog and French Bulldog killing my sod grass? I live in CA and love the green lawn next to my koi pond! Thanks in advance for any helpful ideas!
I don't know of any cheap solutions, but you could try the same product that I use on my lawn when I have a really bad oil leak from lawn equipment or when an area has been sprayed too much with chemicals or whatever that could result into killing the general area.
It is called Brandt 52 Pickup.
It is a type of concentrated liquid carbon that is mixed with water and I buy this from a professional chemical store that primarily sells wholesale products to professional landscapers. Most of these type of businesses will do business with the retail "non-professional" (at retail cost of course) except you might have to wait your turn until they are finished with their primary clients, that is the professional landscape contractors. I generally go when they are not busy such as during lunch or right after lunch.
I have used it to save my lawn due to all sorts of spills such as someone accidentally pouring cleaning products or bleach on the grass or to remove the salt that gets dumped on grass due to shoveling snow or to remove oil spills on grass.
I bet ya it will easily work to remove dog urine.
However, there is one catch. For best effectiveness, the product needs to be sprayed within a few days or so of the incident occurring if you want to save the plants or grass. So, if you wait longer, then there is an increasing chance that the area will need to be replanted or to allow time so the grass runners will cover the spot if it is a type of grass with runners.
Simply just spray the area extremely well. You cannot apply too much. I essentially would spray the contaminated area until it turns incredibly quite black, that is blackest of black. Then, you have to lightly water it into the ground. Then, I would do a second application after this and let it sit for a couple days until it is thoroughly soaked with water for a few hours (such as just sitting a slow running water hose or sprinkler on the area). Also, I use a higher dosage of the product than what is recommended. It is great stuff. This might be overkill, but I like to ensure I do a good job at detoxifying the soil.
It is extremely concentrated. I got a 2.5 gallon jug of the stuff from the contractor store and it took me about a year to use only half of it.
I just used a normal hand held spray applicator.
The product is entirely environmentally safe except there is one disadvantage.
The disadvantage of using too much carbon could result into soil nutrient deprivation. So, after a couple weeks or so, I would then add a little lawn fertilizer to the area that was contaminated to rejuvenate the soil's nutrients.
Also, after mixing with water, still this stuff is blackest of blacks so it can easily stain your cloths and hands for a period of time.
Hope this helps.
