Beginner stuck on what to do next
I am a 21 year old who wanted to do his parents a favor. We have this beautiful landscaping in our backyard that has been neglected for almost 15 years now. It was ridiculously overgrown to the point where I was cutting down weeds that were bigger than trees. I've cleaned it up nicely compared to what it looked like before. But I want to make sure all that doesn't grow back as soon as I move out. There was a plastic cover that was on some of the layers, but the weeds seemed to easily grow right through those. I put down a lot of vegetation killer that says it will last a year. I'm wondering if there is anything more I can do. Thanks for any help.
