Another way to make a selection is by editing through a channel. The neat thing about channels is they only affect the colors within that channel and those selections can be manipulated using layer mask adjustments. Prior to opening the channel, I went back to my select menu and loaded the mask again so the channel would only affect the selection. In this setup, I used a "Green" channel selection. When I do this, the image turns gray. Not to worry as in the next image I apply an HSB adjustment.
Green channel HSB adjustment layer
Again, as I did previously, I applied another HSB adjustment layer and moved the mask up so I could add some additional yellow. I even tossed in a bit of red.
Continuing, I added a masked selection of the sky to do an HSB adjustment. I just did a rectangular selection starting at the waterline, then masked out the leaf and stems at top right.
