I have a question about treating the pool area with grass killer prior to installation.

We have this crazy patch of trees (I haven't been able to ID them) that grows just off of our property. It seems to have runner roots as little versions pop up all over our yard weekly. We just mow them down and they go away. None have ever grown up under stationary objects in the yard but the will grow very close to the edge of things. Do you think we need any extra protection under our pool then the usaul weed killer and landscaping about 3 feet around the edges? Should we put any landscaping cloth under the pool?
