The city I live in has planted trees on everyone's tree lawn. We can't pull them up or cut them down. The tree is in direct line with my front door. How can I combat this poison arrow at my front door? Also, there is a tree growing close to my house that is taller than my house. The tree is located in the front of my house at the northwest portion of the house. I can't afford to cut it down right now so what do you suggest for this problem?
