Bananas at Waihi Beach

We have tried unsuccessfully to get bananas to grow at Waihi Beach. When we set up the lodge we positioned them to make the ambience beachy and tropical. We get them to the stage above and then they just stop as we don't seem to have a hot enough temperature all year round to bring them on.The leaves do ok until we get wind  and then after a while they look like they have been through a shredder

We have tried black plastic bags covering the bananas and many other things to no avail - if any one has any ideas on how to get them to an eating stage we are happy to hear them.

We would love to be able to tell guests about our home grown  bananas to go along with our lemoncello, jams & maramalades, chutneys & relishes, muesli, bread and muffins
