So, I would love some wiser gardeners than I to weigh in on this! Sometime in, oh, probably July, I purchased two beautiful white phlox, tall ones, and no ID saved here. Planted both and both did well until about a week or two ago when one started to die. They are maybe 14 inches apart. Exact same conditions and care. Well, some condition must differ, but what?
We have had other plants mysteriously sicken and die too. A Liatris, when the others are still doing fine, and a couple of coreopsis in a patch grown from seed -- actually, three of those have withered and died.
At first I thought "cat urine" because there are two resident outdoor cats and I know one at least uses the beds as a litter box. But since these two are showing such a distinct contrast, and in case there is some other likely cause, I wanted to ask.
And, can cat urine really do that much damage? Bummer! Imean, I know it's not good, but did not know it could be deadly.
