Shrubs Killed by Dog Urine
I had 8 boxwood shrubs planted outside sidewalk areas up to our front door, which were several years old and doing nicely. I have recently acquired an adult male dog who urinates on the shrubs repeatedly. This caused all the boxwood to die, and I replaced them with spirea. After about a month, they began to succumb to the dog's urine also. I have given up for the time being and have replaced the shrubs with perennials, which the dog seems to bypass. Help!

Dog urine causes burning of shrubs because of the uric acid salt content. Shrubs that are salt tolerant (think seaside plants or desert Southwest) may be more tolerant than some others. However, the best solution is to train the dog to go elsewhere.  It also can help to dilute the salts with lots of water.
