If it gets too dry, yes it will provide little to no flavor to the party. I'm a big, and I mean big fan of using fresh cut wood for my smoke wood. As in maybe a month after cutting wood, I use it for my smoke wood. Big fan of using green/wet apple wood as well, with no curing/drying time. It's what I've found over the years that work best for me.
You should be OK. Some Pits will have fields of wood that they rotate, using the oldest wood that has been sitting for years to actually smoke with. See the wood pile in the link below:
Some people will use both green and seasoned wood together, seasoned wood is said to burn hotter while green wood is said to produce more smoke. Since hickory is a stronger wood, it may benefit more from aging, while apple as Brian uses is milder and may lose most of its flavor as it ages...not sure, just a theory
