Answer: In my experience it can be difficult to start mimosa trees in pots, mainly becuase their root system is brittle and sparse and does not transplant well. Instead I would suggest you set the seed pods this fall on prepared soil in the spot where you would like a tree and allow them to germinate naturally next spring. Alternatively, your neighbor's tree will most likely seed about. When you see a tiny seedling just an inch or two high you can transplant it to the spot where you would like to have your tree. Look for the seedlings to be coming up in late spring to early summer. To dig up a seedling, use a sharp spade and take a generous shovel full of soil with the seedling. That way it will not know it has been moved. Good luck!
