Finally Bananas! almost

I have grown banana plants for a few years now, trying to treat them well so they can have a good opportunity to produce fruit. I just saw that I finally have a cluster. But this week has been heavy frost (for my area) over night and the next few days are more of the same. Is there anything I can do tonight to save it?

Banana is frost tender so the frost in the previous night might already do the damage. It's probably too late this time but maybe you can try this in the future and plan ahead of time.  I just helped my chayote vine survive 4 freezing nights down to 20 F with double layers of 4 mil plastic sheeting with a propane heater inside. I got some PVC pipes and connectors to make the frame so the sheets would stay a few feets away and not touching the plant directly. I measured the inside temperature at 39F ( 200 sq ft by 8 ft tall) when the outside was 20F.
