Pot disintegrated. Root prune now?
I have a small young mulberry tree in a container. It's maybe 4 foot tall. I need to move it for the winter. When I tugged on the container, the container pretty much disintegrated. I'll need to repot. Not on this tree yet, but our leaves our just begining to turn brown now. Should I root prune now or just attempt to stuff it all in another pot? (A larger pot is not an option.)
