Red Banana over wintering
I have two red banana plants (Musa variety) which I've just prepared for over wintering. I've lifted the plants from the ground removing most of the soil from the root ball, cut back all the leaves and drained the rain water that accumulates in the leaf stems. I then placed each plant in a bucket with verrmiculite around the roots to prevent rotting and placed them in the cupboard under the stairs where they'll remain dry, warm and dormant in the dark until the spring.
I based this over wintering plan on a 2014 episode of Gardeners World where Monty Don pretty much did the same (as far as I can remember) with his giant red banana. I've searched online for that clip as a reminder but it's no longer available and unfortunately Monty didn't go through the procedure again this year.
Does that sound like a good plan? Just wanted to ask in case I've missed something. I know the plants like to be dry, cool, dark place over winter so I was wondering perhaps if maybe they would be too warm in doors with central heating. The only other option is to put them in my garden shed but it the temp drops below freezing they might suffer a bit.
All comments welcome
Thanks in advance
