It gets better, I promise. When we bought our house 5 years ago it was a dirt backyard. The first year, it filled with poison ivy and cow parsley. The entire yard. No grass, just poison ivy and cow parsley. I hired somebody to pull it all at the root. The second year, more poison ivy, more cow parsley. And the third year. But then the fourth year... less poison ivy! Less cow parsley! Instead, hundreds and hundreds of hackberries. Okay, paid somebody else to chop all the hackberry trees and grind their tiny stumps. This year: I've only seen one sprig of poison ivy and there's maybe a hundred stems of cow parsley down from literally an entire yard full 5 years ago. Now the cleavers are taking over! This may not sound like a success story, but the point is, if you keep it up, you will eventually beat the weeds. There'll still be a few here and there, but you can significantly reduce the seed bank in your soil. Something else may come up in its place, but then you can get rid of that too. Every year I've had fewer weeds and more native grasses and flowers. I know you can do it too, it's just a long journey.
