The mold only spreads from timber pile to timber pile - it does not appear if there was no mold to begin with. Thus, if timber pile 1 is moldy, it will cause timber pile 2, which is within the 5 tile limit, to become moldy as well. However, there's always a small chance that timber piles become moldy, no matter if they're 5 tiles away from everything else. You should keep a distance of 5 tiles between every timber pile.
Edit: TL;DR: Yes. You need to place them 5 tiles away from each other.
