I had some beautiful hosta damaged by too much direct sun and dog urine. I dug them up, transferred to containers and put them in shade. Should I cut off the leaves damaged by too much sun and dog urine now? What is a better low growing perennial I can put where the hosta were? Is there a plant which won't get damaged by dog urine and which can tolerate hours of direct sunlight? Thank you very much.

Dwarf Rugosa rose shrubs. Urine and salt and disease resistant, and they love lots of sun. They also produce the most prolific, biggest, juiciest and most edible of rose hips (they taste a lot like sweet, ripe apricots with a hint of rosey scent to them). Scads of delightfully scented roses, and the shrubs require very little care and are really easy to keep trimmed very short and compact.

As a matter of fact they're so resistant to dog pee that in my location they are consistently planted as ornamental shrubbery along walkways and paths in our local parks, river and beach dykes and off leash areas where people take their dogs.

I've been trying to persuade the management/owners of the complex where I live and do all the gardening that it would be a good thing to plant a short hedge of dwarf rugosas around the perimeter of the property to keep neighbourhood dogs off the grass.

I have two dogs - a male and a female. They pee on or around my plants. I can't say they have harmed anything except the grass. I dust the grass with lime to sweeten the soil.

"If you have dogs, dog urine has undoubtedly damaged your lawn. Dog urine contains ammonia and salts and these are hard on grass. The salts, especially, pull moisture from the grass roots and cause the grass to die. The ammonia causes the soil to be more acidic, which is also stressful for grass. One easy solution is to add dolomite lime to the urine spot. Dolomite lime helps to neutralize the acid in dog urine and restore the soil to a pH balance more favorable to the growth of new grass." https://www.hunker.com/13405107/how-...g-urine-damage

I have hydrangea, bleeding hearts, mountain laurel, Miss Kim lilacs, lady's mantle, alliums, daylilies, peonies, etc. I haven't seen any damage from my dogs.

What kind of sunlight conditions do you have? Is it early morning sun or afternoon sun?

My Miss Kim lilacs were getting too much sun. I transplanted them to a shady morning with bright western afternoon sun and they look much better. Mountain laurel needs the same conditions as my Miss Kims. I had hostas in this area too but they had sun damage.

Morning sun with afternoon shade is great for bleeding hearts and lady's mantle.

If you post your sunlight conditions, it would easier to respond.
