Canna help!.
The house where I've been working today has just donated a massive clump of canna Tropicana, it's 5ft tall & has a rootball that would fill a 25litre pot, is it best to plant it deep & cut it back? my other option is to divide it up & pot them up?, although I've not really got anywhere suitable indoors for them , if planted deep outside will a wrapping of fleece keep it alive in a normal winter?. karl.

Firstly, does the plant look ok? It may be worth putting a picture up to make sure it's not virused.
If its ok cut back and either leave as is or change the compost and store somewhere frost free, a dark loft/garage/shed is ideal.
April-ish next year divide and pot into smaller pots to grow on ready for planting out around May time.
Basically the same treatment as dahlia.
I left a few out last year and none came back!

I would divide in the spring too. Stored as-one means less drying out over winter than if stored divided now and stored as smaller, individual, tubers.

Re: Canna help!.
If it has that many stems, Karl, I assume it's come through a number of winters successfully. Perhaps you could ask how they have kept it and decide what you would do based on their information.

Re: Canna help!.
Many thanks all, grev the main gardener in the house has deceased & his wife has little knowledge of overwintering plants. There must of been a bed of 20x20ft & at least half was full of these giant canna!!, she briefly told me fred used to sometimes lift them & store them dry?, surely they need some water/soil to survive. karl.

I've done a video discussing various overwintering strategies for cannas.
