Help editing night portraits or blacks

[Patriot]

I done a photo shoot at night time in the complete dark which came out better than expected. However there somethings in the background that I would like to remove, such as weeds and bushes. The problem that I'm running into is that background hold different levels of blacks. This could be from the noise from shooting at iso 400 or the strobes. I tried painting over the black or using the clone stamp tool while taking samples of near by areas. When view on screen one can see the different colors blacks and it is very noticeable that one tried to removed something or hid it.

I first tried using the clone stamp tool and take samples from near by areas and painting over the bush.

I next tried the spot healing tool which also didn't work very well.

I completing new to Photoshop and don't know how to use it fully.

On my screen it looked correct. However someone told me about the error when they were able to see the brush marks. The monitor I use now has deep blacks so I can't see it until view on different device.
