growing on logs

Hello! finally found a forum, looks good. I know its been said that the best time to fell a tree for mushroom cultivation is late fall, or winter or very early spring. The trees here are just starting to bud, and i'd like to give it a try, growing on logs. Will it be terrible or just not as great as when cut at the right time? I have white birch, red and white maple, couple of red oaks. Its a lot of work and I don't want to waste my time..Anyone have any experience with this? thanks
