Is dog urine harmful to lychee trees?

[AnnonaMangoLord45]

Hi, I recently noticed that my lychees have been burning up part of their leaves, but putting out a new growth flush, and i just spotted my dog peeing near the tree. Do you guys have any solutions on minimizing the damage, thanks. Also I changed the soil up until the rootball.

I finally figured out my burnt leaves and even death of a few trees was being caused by the 7% chlorine in the synthetic fertilizer I use to use.
Last year I fertilized a small lychee tree and burned all the leaves off. This year I have only applied organic fertilizer mostly horse or rabbit manure and both of my lychees are nice and green with no burnt leaves. I also like fish emulsion which I made myself this year. In my yard I am more worried about high ph which urea found in urine helps lower. I also add allot of mulch and coffee grounds around my trees. I don't think dog urine would hurt your trees unless you over did it. For me lychees, avocados, COR, seem to really be affected by the synthetic fertilizer

They will do damage if your dog does it on a regular basis. Might not hurt larger trees but smaller in ground or potted plants will take a major dislike to it.

Sorry, but I found the title of this post to be HILARIOUS.

Plants are literally supposed to be urinated on and defecated on because they are in nature so plants have adapted to take advantage of those nutrients.

Yeah but not in excess, in small doses it is fine but if you are talking about plants in a yard copping it every day then it is a different story to nature. I have a male dog 50kgs in weight and he picks certain plants of mine to mark and those plants might cop it ten or so times a day, give them a week or two and the leaves start yellowing and if left they die within a month. His favourites are Eugenia pitanga and pitangatuba. Dont know why only them but i have lost several from him marking them. If you had a big paddock planted then maybe it would be different story if trees weren't getting dosed up as often.

I suspect that this could be a problem as male dogs like to continually mark the same spots to stake out their territory.  It is a common problem for dog urine to burn out grass.  They make products (food additives, maybe treats, etc) that are supposed to minimize this.  I don't know if they would help with trees but I suspect so if they are effective for grass.  You could try locally or check an on line supply house like petedge.
