La Bananeraie Oceanique
Northern France is not traditionally the home of
bananas, but where there's a will there's a way.....

Right: Musa basjoo: Could be the tropics with a
monsoon on the way!
Im an amateur enthusiast of palms, cordylines,
dracaena, cycas and others, but really my main passion is banana
plants, so much so that I am growing them in my flat and pergola
in St Michel in north-east France, and outside, without cover, in
the south of Bordeaux.
Its the Musa basjoo (Japanese Hardy banana)
that is the best adapted to life outdoors, the equatorial varieties
(from Sumatra for example) need to kept away from the cold.
Musa basjoo can be planted in the open air in most
of south west UK just like in France, and in sheltered places in
other countries. In cooler climates they should have protection
over winter by way of a bed of straw; plastic sheets should be avoided
because they tend to keep in the moisture and so cause decay.
Here is an example of growth in a sea climate at 25km
from the ocean at Morceaux:
Apr 93 height 35cm dia. 5cm
July 93 height 110cm dia. 10cm
July 94 height 180cm dia. 14cm
July 95 height 360cm dia. 22cm
The plant reaches its height with leaves 3.5m long
and 60cms wide and - surprise - a flower appears followed by a small
crop of bananas. Only a 40 month cycle to wait until they are good
to cook on the barbecue, laced with butter, sugar and Armagnac!
The winter of 96/97 being over I decided to brighten
up my banana plantation in the spring by removing the least beautiful
ones that appeared tired. I cut them in slices and placed them with
sieved soil around the bases of the others to obtain compost. Three
months later I noticed shoots appearing from these cuttings; Ive
put them in pots and theyre doing well.
While in active growth, Musa basjoo needs lots of
water and a soil rich in potassium, for example N15 P5 K20 + Mg5.
In addition during winter, some 1 year old decomposed stable manure
will fertilize and warm the soil, however, use in moderation. This
magnificent monocotyledon mixes well with other members of its family,
and their growth in summer can be both dramatic and impressive.
One leaf can grow in three days. It is easy to create a banana plantation
in three years thanks to the many side shoots that appear from the
second year onward. These can be planted elsewhere. One such side
shoot can give 20 more within five years. I should emphasize that
you should keep the leaves dry during the autumn and make sure that
the plants are protected over the winter if local conditions dictate.
