View Full Version : Does a corm ever get too old and need to be replaced?

I read that after around 10 years the old corm will be unproductive and that i should transplant a sucker to replace it and kill off the old corm. Is this true?

They replace themselves constantly so if a corn is too old it is because you removed too many suckers and ruined it because once it buds it is done its lifecycle

I didn't see that on two mats of 18 plus years old. the small corm I measured at 18" x 26" and both mats had 38 growing banana mature trunks, plus uncounted pups. I never cut pups from the mat.
But, it could be argued the corms of the new pups were natural replacements and expansion of the old.

Maybe the person advising meant mat and not corm. That would make more sense. They need thinned but not replaced

What is the mat? Perhaps I meant the rhizome

Mat is a large group. They crowd each other out and the large grouping is called a mat. Thinning them out prevents competition for nutrients and space. Individual corms typically don't live long because the suckers keep growing. Many banana cultivars are thousands of years old propagated by suckers.
