I have a more or less wild cherry in our yard and have used trimmings from it.
I dry it before using. A couple months in a dry spot is probably enough. If you're in a hurry, put a couple pieces in an oven with a pilot light or put it off to the side of your grill or smoker where it is hot but not hot enough to ignite it.
I don't bother soaking any wood I use for smoking. I control air to keep it smoking vs. burning.
