Abyssinian problem

I have an Abyssinian banana Ensete ventricosum which stands about 6 feet tall, planted in a large container and over wintering in a heated workshop which is held at 10 degrees minimum. For some reason it has started falling over. It is bending at the soil surface. Some leaves have kinked over while others are upright and a new leaf is opening. I have supported the plant back to vertical but it is still floppy if I remove the support. The moisture gauge is in the mid green. Any ideas anyone? Not sure what to do next.

 

Might be because the light is coming from one side, is it bending towards the light?

I'd be inclined to dry it off a bit and remove a few leaves, let it go dormant for the winter.

 

The light is from above through the roof. It is not bending. It is like a hinge, as if the stem has broken which it hasn't.

 

Only thought that crosses my mind then is has it rotted off at ground level.

 

I agree with the drying off process.
But I leave the leaves on to dry the roots and pot out, then cut the leaves off when it's dry.

Another thing it will need is ventilation, you don't want big temperature changes as it can lead condensation forming on the stem and in the leaf axils.

 

Could be. There are roots like thin fingers reaching down from the base but further in it feels soft and slimy.

 

This looking like the favourite option. Thanks.

 

Similar to what others are saying. Thanks. It seems scary cutting all the leaves off and baring the roots. One would think that is the best way to kill it. I have seen Monty do it but it seemed drastic. However I shall try it.
