Hello Banana Fans,
As you know some banana for example Cali. Gold is prone to choking very
often.
There may be various reasons for choking and , then preventing methods
may differ from case to case.
Are there anything to do for preventing it?
Your ideas or opinions are welcome and thanks in advance.

Unfavorable conditions(temperature) during the growth cycle seems to cause choke in certain cultivars.

Choking. When the distance between the petioles (leaf stalks) of alternate leaves is reduced, the plant takes on a “choked” or “rosette” appearance. This is commonly seen during late winter to early spring. In August(remember this is New South Wales, Australia); bunches may fail to emerge properly. This is common in Dwarf Cavendish but not so common in Williams variety. Choked bunches are prone to sunburn and produce fruit difficult to pack. Choking can also be caused by high temperatures (above 30°C) and drought.

BANANA Choke throat It is due to low temperature affecting active growth of the plant. Leaves become yellow and in severe cases, the tissue gets killed. In case of normally flowering plants, the stalk carrying bunches elongates freely so that the entire inflorescence comes out of the pseudostem and hangs down. Bunch development is normal, but when the time of flowering synchronizes with low temperature, the bunch is unable to emerge from the pseudostem properly. The distal part of the inflorescence comes out and the basal part gets stuck up at the throat. Hence, it is called Choke throat. Maturity of the bunch is delayed by taking 5-6 months instead of 3.5-4 months for harvest. Provision of shelter belts using Casuarina or Eucalyptus to prevent the effect of cold wind blowing into the orchard and planting low temperature tolerant varieties like Kullan check the disorder.

Climate
Banana a humid tropical plant, comes up well in regions with a temperature range of 10°C to 40°C. Low temperatures(less than 10°C) are unsuitable since they lead to a condition called “Choke” or impended inflorescence and bunch development. Wind velocity more than 80km causing harms to plantations.

Choking can be prevented.
Choking hazards include:
Coins
Buttons
Toys with small parts
Small balls, marbles
Balloons
Small hair bows, barrettes, rubber bands
Pen or marker caps
Small button-type batteries
Refrigerator magnets
Pieces of dog food
Choking Hazard Foods
Some foods can cause choking.
Keep the following foods away:
Cali. Gold
Hot dogs
Nuts and seeds
Chunks of meat or cheese
Whole grapes
Hard or sticky candy
Popcorn
Chunks of peanut butter
Chunks of raw vegetables
Chewing gum

The typical phnomenon of my Cali. Gold is that petioles don't extend and
soon next petioles are emerging and then the petioles stay in the same place
and each petioles are too tight to develop further petioles.
It looks like a travellers palm.

I have not had that happen with CG but I have with SDC.

The overwintering temperatures could be some how insufficient than Cali.Gold feels satisfactory.
I overwinter Cali.Golds in a sunroom that is only heated by natural sunlight
and not electric heateror or simillar.
Even in the midwinter, teperatures don't drop under 5℃, do you think this
could be a reason for choking?

Hi! How can we say that the distance of the Petiole is already choking?

Many of mine tend to do that, it is some kind of problem in the corm. I call it the umbrella effect, the leaves keep coming out, but the pseudostem never gets taller, eventually resembling an umbrella. It is either nematodes or weevils I think. If I dig it up and clean it of all damaged flesh then replant in clean sand, it grows well for some time but it comes back. I believe it is a nematode issue. Last spring I atom bombed my bananas with several insecticides like Spectracide and Sevin and one more plus a fungus that is supposed to parasitize nematodes and kill them. Something worked but I have not definitively determined which. Whatever it was, it only worked for a short time, like a month or two. I retried all the insecticides separately with no results and have recently found some more of the fungus and begun applications, but being winter it's tough to see results.(It can be tough to come by.) Last time I had only 100 grams of the powder, enough for the one treatment. This time I got 1.5 kilos, 15 times what I had last year, so I can treat and retreat for better results, assuming it is the one that worked. Once I have some results I will post them here, if it works.
