Do dog urine kill fern plant?

Yes, dog urine can harm fern plants due to its high nitrogen content and acidity, which can lead to leaf burn and other stress symptoms. The concentration of nitrogen, especially in concentrated areas where a dog frequently urinates, can overwhelm the plant's ability to absorb nutrients and water. Consequently, this can result in wilting, discoloration, or even death of the fern. It's best to train dogs to urinate away from sensitive plants to prevent damage.
