It isn't often I post other people's work on my blog. Several people have contacted me they have grown bananas here in our hot and cold desert but I thought the information here should be posted for comments and discussion. Harrison sent it to me in 2015. Yes, I'm slow.

A successful strategy for growing edible fruiting bananas in Las Vegas has not yet been found; it is
a challenge to match our environment with the banana’s requirements. That said,
it is marvelous to watch the huge purple flower emerge and slowly expose tiny
green bananas, even if they are not able to mature into sizable yellow fruits.
Banana plants are usually not available in local nurseries
so mail order is customarily
required. Common cultivars are a good choice, and
note that not all banana plants are edible fruiting. Search the Internet for their
current availability. Order from resources that provide safe packingand
shipping, and the shorter the travel time the better (the expense of air or two
day shipping is sometimes worth it.) The plants will be shocked from travel in
any case. Best time of year to order is spring. Fall ordering leaves short time
for the plants to acclimate before winter protection must be placed.
Location. Daylight and sun light are two considerations.
When the days get short, say less than 12 hours, their growing slows. That is
why overwintering them in a dark garage is not a
good idea. They may never
recover, and it can get dangerously cold there in winter. In our climate,
bananas can tolerate heat but do not tolerate direct sun; broken shade is
probably a best location. They should be planted in the warmest microclimate on
your property. In my opinion, the growth of the plant is best if it is continuous
and not interrupted by cold, wind, or heat. Banana plants tolerate wind, but not
a hot, dry desiccating one, so limiting exposure to wind is also a
consideration. In-ground (not in greenhouses) bananas require serious winter
protection, strategies for which are available in nursery catalogues.
Soil. Planting either in the ground or container, native
soil is alkaline and bereft of nutrients. Various formulations have been given
to improve the soil, for example, perlite, peat moss, potting soil, 33% each.
The ultimate pH should be on the acid side, between 5.5 and 6.5. Well draining
medium is preferred, and a generous bottom layer of cactus mix will enhance
drainage.
Fertilizing. A well-balanced product, either 6-6-6 or
12-12-12 should be satisfactory. I recommend applying fertilizer first when the
weather warms up and once in early fall. Some recommend more frequent
fertilizing and special fertilizer combinations of nutrients.
Watering. For container plants, mulching and using a “water
stick” is a useful guide to determine plant watering needs. In-ground plants, also
mulched, are regularly watered, once per week for 15 minutes in Winter,
increasing to twice per week in Spring, and perhaps once more per week at the
height of Summer. Observation of the leaves, drooping when dry and discoloring
when too wet, is also helpful in modifying watering schedules.
Fruiting. Between 9 and 12 leaves suggest the plant is
potentially able to fruit. If you count the leaves on pictures of fruiting
plants in nursery catalogues you will note they almost all have at least 10
leaves. Preventing leaf loss is critical to successful fruiting. After
fruiting, it will take 2-4 additional months for fruit to ripen. I have not
found measuring the girth of the pseudostem helpful in predicting flowering.
Pests. I have not noted any specific pests, but focused
observation on plant growth should detect harmful conditions.
Propagation. Bananas are easily propagated, once you are
able to grow them, even if they don’t grow edible fruit. From the base of the
mother plant, little plants surface, and can grow to be mature plants. These
offshoots are called “pups,” and are the same cultivar as the mother plant.
Following the suggestions above, I have found complete success,
i.e., growing edible fruit, elusive. I have been able to get fruiting but the
fruits do not grow or ripen; they are small and inedible. There are still
adjustments to try, for example, timing the cultivation of “pups,” the root
offshoots from the mother plant, to allow for a longer uninterrupted season may
be one strategy.
For me, growing edible
bananas in Las Vegas is a work in progress.

So the banana tree is a three year lifespan typically is my understanding?
ReplyDeleteIt depends on which banana variety. Some of them produce fruit quickly resulting in a short plant while others may get older and taller and take longer to flower.You might take a look at this website for more information in growing them in colder climates. https://homeguides.sfgate.com/seasonal-growing-stages-banana-tree-57638.html
DeleteI've gotten fruit 2 years in a row now with our dwarf Nam Wah patches in 89123 (Wishing Well Estates - old neighborhood). I'm still waiting for the bunches to ripen this fall, but I expect to be eating fresh harvested dwarf nam wah bananas for the second year in a row in November. I should have at least 2 viable bunches to consume this fall.
ReplyDeleteOur plants get substantial frost damage, which hinders their ability to put out larger bunches of fruit. My plan this winter is to pull a few stalks and store them in my shed for spring planting to avoid frost damage. They store like a bulb over winter.
