Not the greatest job of removing it, here.
Advice: When grabbing a clonestamp source, always choose one that's as far away as you can possibly get from the area you're going to paint, but still the correct texture/lighting.
If you grab something right next to the area you're painting, the patterns will be close enough to be obvious repeats, like the dozens of blades of grass that jump out at you here as being identical and an inch away from each other. If you had grabbed grass from far left to clone the posts on the right, and vice versa, it wouldn't show up like that. Same goes for anything cloned ever. Only grab nearby textures if they are very smooth and consistent and not uniquely identifiable.
Unrelated: The image feels a little snapshot-y. I would suggest a much wider aperture when the background is as unimportant as this. Basically as wide as you can get while leaving the house still in focus throughout. In other words, when the focus is the HOUSE, not the land around it at all, like this, treat it more like a portrait than as a landscape.
