on the ground. Right? So does a landing aircraft really have to worry
about wake turbulence from a departing aircraft?

Only if you land past the point where the departing aircraft broke
ground.


But couldn't the turbulent air be blown back towards the beginning of the
runway by a strong headwind, perhaps even beyond the threshold ?

I suppose that is theoretically possible, but most airplanes large
enoguh to cause serious wake turbulence probably don't lift off until
4,000 feet down the runway. With a wind strong enough to push that back
to the approach end in any reasonable time, the turbulence from the wind
woudl likely break up the vortices to the point where they wouldn't be a
big factor.

I never say never, but I think this is a very remote possibility.
