Therefore, I strongly urge you to put them in extra-large pots, meaning 24″ and larger. If you want to create a combination planting, go bigger!For planting in pots, fill a large pot to within six inches of the top with a well-draining potting mix into which you have added a little peat moss and perlite. Place one rhizome into each hole. If your pot is large, you can plant two or three cannas in each pot.After planting, it may take 2 weeks or more for the first shoots to appear.
