I've read up on several tips to deal with this topic including the use of fill-flash, etc.  What do you specifically do to deal with the green cast when taking photos in the woods?

You could do a manual white balance off of a gray card, or do a custom white balance under those conditions, or just shoot the gray card in the same light and then use that as the basis for your WB/Tint adjustments in your RAW converter.

This is what I do as E.J. said "shoot the gray card in the same light and then use that as the basis for your WB/Tint adjustments in your RAW converter".

There are numerous techniques to deal with color cast. I do color cast / balance adjustments to every single image I process. Some need no adjustments and some full color cast correction. Are you doing any type of color balance now in post processing that seems to not be producing the results you are after?

I can post steps to a simple but effective adjustment I do in Photoshop if need be. If you happen to have something like the NIK software plugin it provides color correction adjustments as well within the Pro Contrast, White Balance, Color Cast Correction tools. Each one I use produces a slightly different result. Many times I check color balance more than one way and then choose the result that best fit what I want for the final result.

Thanks E.J.  This is one of the suggestions I had read about.  I need to find  a way to carry a gray card into the woods.  Has anyone made a folding gray card yet?  There are the portable ones about the size of a deck of cards.  If you're shooting with a big lens, say 500 mm, how do you place the gray card?  Stick it on the side of a tree, angled against a rock, etc.?  I just had an idea.  Bring a smaller lens and take the WB with that and then put the 500 back on.

PS.  One of the very best things I ever did for shooting indoors (curling rink) was to use a gray card. This was back in 2002 with the P&S Canon G2. The colour in the photos came out looking really good.  But the lighting in those rinks are good anyways.

Yes, there is a great little collapsable one that I use sometimes. It's called the Impact QuickBalance:

It collapses like a window sunshield into a small pouch.

In the film days we would add a magenta filter 10cc works well as a one size fits all (carried a range of them) or do as I did and carry a color meter.  While green is the principal problem, in spring the leaves and/or blue sky can also change the color temperature so I carried 81 (used a lot), 85 and 82 (82 rarely use) series filters. Still use 85c for blue sky shade (think backside of ridge, valley or canyon where only light is from blue sky and color temperature can go beyond 10,000K) to keep from "underexposing" so to speak the red and green channels making final adjustments based on clicking a neutral in photoshop. Today, I just make sure there is something (a neutral) I can balance off of in Photoshop (just click on it) even just taking a shot with a small gray card and then removing it for the final picture.  I find photoshop automatically makes the adjustment just fine for my work.  Faster than doing a custom white balance in camera and "film" is cheap.  I'm doing flowers for field guides so accurate color is important (have used xrite to produce icc profile for sensor which is probably not necessary).  As to the telephoto, if you are in the same light just stick the card in front of the lens.  it really should not need to be in focus.  I use the WhiBal cards roughly the size of a credit card also available from b&h.

You just have to place the gray card or whatever you use under the same lighting as your subject is in, i.e., if you're standing under the same lighting, you can just take a shot of the gray card where you stand and use it to do white balance in post processing.

In fact, you don't even need a gray card (which is better for setting exposure). You can simply use a piece of white or black paper or anything with neutral color, i.e., white, black and gray.
