Although they typically don’t bear fruit in Northeast Florida, banana trees do grow in our subtropical climate.
But, because our climate isn’t quite as warm as it is further south, extra care must be taken to avoid the plants dying off during our mild winters.
The first step is to stop watering your banana tree as often during the winter. Add just enough water to keep the ground moist. When freezing temperatures are expected, however, make sure to water the plant thoroughly and check it again after the freeze passes.
When temperatures drop below 55 degrees, stop fertilizing the plants as well and add additional soil around the trunk of the plant to help insulate it from freezing.
Also, make sure to cover your banana plant with a blanket or tarp during freezing weather and remove only the dead foliage after the freeze passes.
