Q.Ground Cover
I am in zone 6. I have a 65′ x 45′ lot behind my privacy fence. I would like to use a low maintenance , fast growing ground cover in that area.
Thanks.

Thanks, that sounds like it might be a good fit for what I need.

Be careful what you ask for! Any "fast-growing" plant is going to spread into adjacent areas. You don't mention how much sun the area gets or type of soil. Another consideration is how much you want to spend. You can search for groundcovers in your state or check your state extension service for recommendations. Given how large the area is, I recommend a product called Eco-Grass. https://www.prairiemoon.com/eco-grass-low-maintenance-lawn-alternative.html
