Struggling Musa basjoo

So my Musa basjoo seems to be struggling.
Stem is about 5ft and survived the winter.
But every leaf that unfurls seems to disintegrate.
And no real growth so far this summer.

Any ideas?

 

Firstly mine is only just making entire leaves, its been a cold windy spring in my experience.
I think yellowish leaves are fairly common early in the season, my thoughts are, that as with a lot of overwintered stuff, the top starts growing before the roots.
Mine recently, not particularly ornamental at the moment.

 

The leaves go yellow and literally fall apart as they unfurl.
It's a sheltered spot, so I doubt is wind damage. Certainly doesn't look like it.

 

It will grow out of it, soon I would think.

 

I suspect Pete is right. I have a couple but know nothing about them.

Because its cold up here in Yorkshire I overwintered mine in a conservatory, where they were looking very happy. Then I put them outside and they were totally shredded - I know that isn't your problem. Mine had become very soft inside where there is no wind, and couldn't stand up in the real world outside. But they are slowly recovering.

 

It's going slowly backward.
Each leaf that comes out seems smaller and weaker than the previous one.

Not really sure what's going on with it

 

OK, that dont sound good.
Sounds like the roots are not moving.
Could it be rotting off at the base?
