Hi,

I have a bannana plant (Musa Bajoo) in a pot that has grown so long
that it is taller than the patio it is on. I feed it on loads of
chicken poo that it loves.

Can I shorten it and when?

The "trunk" of the banana tree - which is actually an oversized
herb, merely consists of compressed old leaves. It performs no
real function in terms of keeping the tree alive - nutrients
and water don't travel up the "trunk". Each new year's growth
grows up through the middle of these old leaves - rather like
a perennial leek would grow. The entire trunk can be cut back
as hard as you like, but at the end of the growing season.
If you did it now, you'd kill off this years growth as well.
The only danger then might be increased exposure to frost
from above , (although presumably frost danger to the roots
through the pot would be the same ) and so maybe the potted
plant could be moved to a frost free site - the garage etc
over winter.

Many thanks, very interesting. I shall cut it back in the autumn, wrap
the pot in bubble wrap and take it into my cold greenhouse where it
usually overwinters. Is this OK?

I was going to ask how you overwintered it but that answers my question.
If you have successfully produced such a large plant it seems a shame to cut
it back. Could you plant it in the garden (if you have one). It only needs a
small amount of protection to keep the leaves and trunk OK during the
winter. Even if the frost cuts it back it should resprout.
