Re: Bananas for trade
I have that center turned to black on one of my Dwarf namwahs.
I think when cold rains during the winter falls down into the unfurled leaf, it gets collected and starts accumulating fungi, bacteria, and since the banana plant is inactive, it could not push them out and therefore will rot away.
I think we may need to cover the top of the trunk (after cutting the leaves) with jute sack and then a plastic liner and tie it. This way it will keep water out, and also any condensation inside the plastic will be absorbed by the jute sack.
i will do this during the coming winter.
