About divisions?
Is there any good reason not to drop this one big chunk (last picture) as is? Over the years I've just considered cannas seasonal and replaceable and I've saved a few that looked alot like my first pic. Last year's Robert Kemps, and seedlings from the previous years RK offered some rather huge clumps of rhizomes. I've potted some other varieties and I know it doesn't take much of a good chunk to make an awesome, enjoyable plant.
See the last pic, and is there any good reason not to plant it "as is"? Last pic is on a 16"x16" cap and I could easily pull or cut pieces off but I have no need to (no shortage of canna by anyone's measure). I am tempted to see what 3-4 commercial bags in one chunk provides but I'd prefer some expert advice before experimenting.
Thanks!
