    There are dozens of posts at this site regarding background removal. Have you tried anything yourself?

You could use the Channels as a starting point to make a mask.

  1. Control CTRL+click on a channel to make a selection from it, then back in the layers panel, add a layer mask.

  2. Then you can edit the layer mask by selecting it, and paint on it directly. If you set a soft-edged Brush to Overlay mode, and lower its opacity to around 50%, then you can paint in black to mask more, or paint in white to mask less areas.

  3. You can also apply a curves or levels adjustment to the layer mask to try to improve it.

Here's how I would handle it for this image:

  1. Make a rough cutout of the subject so there's less background information to visually process when you're editing.
  2. Duplicate the layer.
  3. Set the duplicate's blending mode to Multiply.
  4. Ctrl+Alt+2
  5. Use this selection for an inverted mask on your original cutout layer
  6. Adjust the mask as necessary.

For the last step, I rely heavily on curves and selections. You can use the transparency selection you made earlier to restrict what parts are affected by the curves tool. Magic Wand with a 3x3 or 5x5 sample area is also okay. Use the history brush to bring back really fragile areas like the tendril at the bottom.
