Canna Lilies

[roadkill]

Should the tops of the large canna lilies be cut off after flowering?

[greenfingers]

At this time of year you need to get rid of all top growth, dig up the rhyzomes and store in dry compost in a frost free greenhouse or shed or even wrap up in a newspaper bundle until next Spring, unless of course you live in a mild frost free climate then you can leave them in the ground.
