Q.Overwintering Musa sikimensis ‘ Red Tiger’
Have been growing a few Musa and Ensette on my allotment, all doing very well. I know the Ensette ventricoum murelli is tender, so will have to dig that up and overwinter it in a frost free place. But have two musa, one called Musa Basjoo, which I know is pretty hardy, but the other Musa, which is Musa sikimensis ‘Red Tiger,’ is meant to be root hardy. I have been told conflicting things about this plant. Looking to over winter it outside. I live in North London and have created somewhat of a microclimate on my allotment. Would be grateful for any advice in over wintering this banana.
