Planted some cannas last year in large pots sunk in ground
........overwintered in greenhouse ........today found they have huge tubers
.........can i split them in some way to give even more plants

All advice welcome

Yes - if you don't they will probably split the pots by themselves (she said
speaking from experience!)

Cut or break apart and repot in fresh soil. I have supplied all my
friends/rellies with the offshoots over the years :~))
