Removing green blur from nature photo

[ellie_cat]

Hi. I am new to this software. So forgive my questions as I attempt to learn. 

I took this picture of a night heron as jpeg, and as you can see, there are some green blurred areas in the foreground. This is due to some out-of-focus blades of grass between the camera and subject. 

How would I go about removing these green blurs? 

Thank you.
