Tree growth

Simple one I hope but trees have a certain amount of hit points, small hardwood have 260 hit points and give 2 log, 3 long sticks and other stick, bark plus 2 firewood. The larger has over 300 hit points gives the same logs and long sticks but more firewood and same for the Fir with Max hit points of 300.

My question is if I wait a year do the Fir with 260 become Fir with 300? I seem to struggle with firewood is all
