If the first deviation from a controlled and intended flightpath was hitting trees, it was CFIT. Anything that subsequently happened (and in my book all that in all probability subsequently happened was, seriously damaged, it hit the ground beyond the trees) is not the cause of the accident.
If it didn't hit the trees but a 'close encounter' led to a sudden climb and loss of control in IMC, then it wasn't CFIT.
