Hi,
This is an example of content aware fill:

Essential steps:
1) Created a path around the bush
2) Made the path into selection (feather 2 pixels)
3) Pressed delete and used "content aware fill"
Conclusion:
It works in this case. Some artifacts can be seen, but probably not obvious if you don't know what to look for. Your mileage may vary...
Best regards
Erik
