Storing banana corms for winter

islandbreezeOctober 20, 2008

I plan on digging up my bananas and ensetes tomorrow, and storing them in my garage over winter.

What type of substrate should I use? I want to make sure they don't rot. Last year, I tried this with a large clump of Dwarf Cavendish, but I used soil from the ground. The stems froze and the corms rotted. I have heard of people suggesting Spagnum peat moss. Is this the best option?

I look for something that is:

1) lightweight
2) porous/well-draining
3) Cheap!

So, when I did bananas, I try to remove a good bit of soil from the roots, trim back the longest roots, fit the plant into the smallest pot possible, and fill in with 1/3 Miracle Grow potting soil and 2/3 with an inexpensive soil additive called Claybreaker. It's mostly pine bark and gypsum. It's used to break up clay soils. It's pretty cheap at Home Depot and goes a long way. It looks a lot like mulch.

...and by the way, I only trim the pseudostems down to about 3 feet. I keep them in my garage. They are usually starting to put out leaves again by April.
