While walking your dog, be careful where you let them pee. Dog urine is a detriment to our lovely urban trees. Dog urine severely harms the base of trees. When a dog pees on a tree, the chemicals from their urine soak into the bark. They then reach the cambium (the tree tissue layer, tasked with sending nutrients throughout the tree). This layer is then damaged, destroying the tree or impacting its growth.
In fact, it’s important to keep your dog away from the base of trees as well. When a dog pees on the soil around the tree, it can create a salty crust, which inhibits water absorption. During these hot summer days, it is as important as ever to make sure our trees are getting enough water.
