Growing bananas in the UK
3rd December 2020 at 8:25 am #14645
Bananas are in a group of about seventy species in the genus of Musa. They are indigenous to India, SE Asia and Northern Australia. They are not going to be used to the type of winters that we get in the UK!3rd December 2020 at 8:31 am #14646
What temperature will banana plants go down to?
The leaves of Muso Basjoo will stop growing at 12 degrees Centigrade. They will start to get leaf damage at zero degrees centigrade.
A young pseudostem will die at a few degrees below freezing but a more mature stem of a thickness of 4-6 inches will tolerate temperatures down to minus 8 degrees Centigrade.
The rhizome roots will survive prolonged periods of average sub zero temperatures (0–8 degrees centigrade) but the leaves and stem will die back if unprotected3rd December 2020 at 8:33 am #14647
How to protect a banana plant from frost?
The first thing to do though is to cut off the leaves. Do this after the temperature has gone low enough to blacken the edges of the leaves. This triggers the plant to go in to a state of dormancy.
Then wrap the stem in a few layers of horticultural fleece. This will have to be tied to keep it in place. If you live in a fairly mild winter area this might well be enough but for harder areas then you are going to need further protection. Hesian sacking can be wrapped around the fleece. This is quite awkward stuff to get in place and will have to be tied like the fleece. make sure that the ties have a bit of play and are not strangling the stem.
For the really cold areas you are going to need a further layer. The most effective insulator for this is straw. the problem is getting it to cover the stem. One method is to make a chicken wire cage around the stem, held in place by a couple of stakes. This can then be filled with straw.
The problem with any wrapping is that the stem can easily start to rot if it gets wet or has no air circulation for extended periods of time. To help to alleviate this, the stem needs to have a final outer layer that is waterproof. Old washing line covers are ideal. The stem should also only be covered when there is a real risk of very low temperatures.
The roots should be covered with a thick layer of mulch.30th August 2021 at 9:45 pm #20705
Can you leave ensete bananas outside in the winter?
Ensete ventricosum ‘Maurelii’ are not frost hardy and must be taken in if low temperatures are expected. To over winter the plant you must first let them dry out. Do not water them at all over the winter as they are prone to rot. To over winter first cut the leaves off near the stem. next turn the plant upside down and hang up for a week. This will drain off any internal liquid. The plant can then be stores in perlite in a dark place between 5 and 15 degrees centigrade30th August 2021 at 9:50 pm #20706
Can you get bananas from a UK banana plant?
This is about as good as you will get if you are very lucky from a muso basjoo. Apparently cavendish bananas can produce bananas if grown all year in a conservatory8th September 2021 at 12:37 pm #20932LeslieParticipant
How hardy are Cavendish bananas?
Cavendish bananas must be treated as an indoor plant. They can go outside in the summer but as soon as the temperature goes below 10c they must be brought indoors. They cannot be dry stored like ensete and must be kept as a houseplant in full light with temperature 10c +8th September 2021 at 12:41 pm #20933LeslieParticipant
How big do cavendish bananas grow?
Cavendish bananas can reach about 2m in height. Their leaves tend to be more upright than musa basjoo but they do not grow as tall25th October 2021 at 5:48 pm #21858
Ensete banana over winter dry storage
Wash any excess soil from the roots and then turn upside down for a week to dry out the moisture.
