Propagation: Splitting Bleeding Heart?, 1 by Zarebeth

My DB is putting in a deck for me, and unfortunately it is going to cover an area where I have a huge bleeding heart. I mean huge - it gets about 3-1/2 feet tall and just as wide. I figured while I was digging it up, I might as well divide it and plant it in front of my new deck, but I read somewhere they don't like to be disturbed. To make matters worse, it is already coming up!

Is it too late to move it, can I split it, and will I kill it if I do?
