One wants one year old wood. New branches basically. I've used one that were between and 1/8 and quarter inch and they turned into trees but bigger ones are better. They have more stored energy to shoot roots and stay alive. Keep the ground wet they are in for the first couple three weeks, not saturated and they'll grow.
If you can find where a branch broke off there will be some good shoots to use, check near the base of the truck and withing the first few feet of the ground
