the chances are better if dormant but the last 3 i did they were leafing out. i rub off all except 2 leafs and stick them in the ground up to the bottom leaf. they usually root. elders , aronia, blackberries, raspberries, serviceberry, blueberries and mulberry cuttings all root pretty easy. its crazy how much they sell these plants for at the nurseries considering how easy they are to propagate.
