Branches as fuel, how to dry and store them

I was looking at my pollarded mulberry and thinking about how one would use the wood from it in a RMH.
I'm sure green sticks will burn in a rmh, but I doubt they are ideal.
Those of you who have an RMH, how do you prepare these green branches for burning?

If I've got some pieces that I think aren't completely dry, I lay them on the top plate while the RMH is going. Turn every now and then, and for small diameter branches and kindling it's often dry enough to burn in an hour or two. I suppose this would work with green prunings as well, but might take a little longer to cook all that water out.

Hi William,
I'm sure branches would not take as long to dry as traditional firewood made from the trunk of the tree, but would probably still take a while. I don't see why you couldn't treat it the same way though. Put it in a sheltered spot (preferably south facing) and let it sit for at least 6 months, if not a year.

Phil, how do you store them?
I've only kept branches for charcoal making.
Stuffing them in garbage cans seems very inefficient, but they also are not the easiest thing to stack.
I've considered bundling them, even though that's more work.
I might just be thinking too small.
What is the smallest size of stick you bother collecting in bulk(excluding kindling)?
