cutting pine

[TexasTimbers]

I have some more loblolly to cut. My understanding is that is should be cut "before the sap quits running"? How do I tell if it's still running (zero comes out when you cut into it?) and if it isn't running should I wait til it starts again?
I want to cut it now and use it next year or year after for TFing. I guess cutting it now and using it now is right out?

Pine cut now, into 4/4 will be about 20% in 6 or 8 weeks.

The only benefit you may get by cutting the pine in the winter is a lack of bugs and diminished blue staining and mildewing.

We cut, saw and build all year here.

sap will run out of the stump regardless of the time of year, mor will just run out during the growing season (spring, fall)
