Pet waste and my lawn

Asked May 17, 2018, 3:08 PM EDT

I have an endless battle trying to keep my grass alive in the areas my dog uses to go to the bathroom. I try to water that area frequently and to pick up waste but I can't seem to maintain grass. Reseed every spring, wondering if there is a certain variety of grass seed that is less susceptible to the nitrogen burn. Tried gypsum a long time ago without much luck but also wondering about something that I can put on the lawn to help neutralize the nitrogen. I recently got a seed/mulch dog repair product that said it had charcoal in it--also saw a product called biochar in a gardening catalog and wondered if that would be helpful. Appreciate any advice.

Information in this University of Nebraska bulletin isn't specific to "dog spots" but it addresses your question in general. Most of the information in it also applies to Minnesota.

Although it's easier to grow tall fescue in Nebraska than Minnesota, it might still be a good choice. Go here to learn why:

We don't have any research-based information related to the effectiveness of products marketed specifically to repair dog spots.

Following is a bulletin that discusses the topic in detail. Again, most of the information applies to Minnesota as well as Florida. (We realize you may already have read bulletins like this one.)

The warm weather grasses mentioned in the Florida bulletin are not suitable for growing in Minnesota.
