Arbutus: Propogating Arbutus from cuttings

I was forced to trim my arbutus tree as it hung at eye-level over the sidewalk. I intended to use the cuttings as stakes or in trellises, and stuck them in a bucket, which just happened to collect water over the winter. Unbelievably, the branches are making leaves!
How do I plant these branches? They are about 3ft in length, chopped at both ends, so if I planted the bottom end, it would make an ugly tree, as the top would be chopped. The nodes on the top two-thirds of the branches are all growing buds. Any suggestions?

 

Hello Alison,

Are there any roots?

 

The nodes that are underwater are a little larger than they used to be, perhaps the beginning of roots but it's hard to tell.
