Re: What root rot?
Many people here have experience with real root rot, and I expect it is because we do not have the tropical growth rates found in SE Asia.

Light, water and nutrition. Light you have at average much more in sunny California than in misty northern Vietnam, where this picture was taken. Even though your daylight hours are shorter in California, you make up most of it in brightness. The rest you compensate in summer. Remember I stipulated green leaves. With nutrition you are on your own, but I submit, that the average North American grower provides better soil and fertilizer, than the bananas on the picture get. That leaves water. Through greater evapotranspiration drier climates you get greater throughput of water. That is clearly a help against root rot. Having said all that in those almost four years, I have not heard of one case of an actively growing plant suffering root rot, even in plants, which grow very slowly. If you chop or freeze off the leaves, then you have a plant, which is half dead and subject to all kinds of rot, root, corm and PS. Otherwise root rot is just a big fat boo-boo man, like a monster under your bed. Don’t get me wrong. I do not suggest, that you submerge the corm or roots of your plant in water, but as long as you have green leaves and a bottom drain hole, you will not get root rot in a banana, no matter how much you water. |

wandering Jew (purple heart) are completely immune. I have watered a philodendron for years by filling up the tray, in which its pot was sitting, with water and it developed a veritable jungle in my living room (I was still a bachelor then). I would not want to do that with most house plants. But under conditions, I specified below, a banana will not develop root rot. |

Re: What root rot?
After close inspection it seems to me these are planted on a raised berm and are not in standing water.
There is a distinct bank/waterline and then the berm, and it seems that this is the growing and irrigation method of the landowner, rice, taro, or pungi sticks on one side with a row of bananas as a separator. Pretty neat photo. Take some interesting photos to share on your journey to Vietnam |

ridge between two ponds of standing water to achieve root rot, but you could achieve it by watering plants in a pot with a drainage hole? Quote:
matter, because we do not have enough grow time between frost to achieve either fruit nor bloom here, but since you brought up the divergent growth rates, maybe you can substantiate them? Especially the somewhat hasty growth rate you indicate for SEA leaves me interested? Thanks, Olaf |

to do with root rot? Quote:
Vietnam tomorrow morning, at a time, when it should be illegal to get out of bed. Don't let that discourage you to dig up more evidence of root rot. I will be in touch again. when I am there and recuperated from an almost 50 hours bed to bed trip. I might even be able to squeeze in a reply to your last paragraph, before I leave, - depends wow it goes :) Best, Olaf |

Re: What root rot?
You can bet, Richard, that I will take lots of pictures. In the past I have relied
on such trips on internet cafes, but since there is now WiFi everywhere, I am dragging my laptop along and will accordingly be equipped to upload my photos to Picasa and subsequently to my Flickr site. :) |
Re: What root rot?
First of all here is a copy of a brief explanation, as to why I am still here, which I
sent out to a number of people: The vacation, that wasn’t (this explanation will go to several people and is therefore not personal) It was a disaster throughout. When we arrived at Kelowna airport, our flight was first delayed and then cancelled altogether. When we tried to re-book, we were told by the Air Canada representative, that Westjet had booked anything available for their customers. Any flights, which were available to us, would have gotten us to Saigon 3 ½ days later and one hour after the flight we had booked out of Saigon had left. Add to that that the time was leading up to Tet, the number one travel time in Vietnam, when all the families try to get together, getting flights and hotel reservations, which were not pre- booked much earlier would have been impossible. So here we are again in chilly Penticton instead of warm and cosy Saigon. After we arrived back, we had to send our house-sitter back home and begin a frantic quest of cancellation of all reservations throughout the six weeks we had planned to travel in Vietnam and subsequently rebooking everything for a new trip starting Jan. 27, to Mar. 17. Best, Olaf Now back to the subject on hand: Richard I have tried the URL, you supplied to back up your contention of divergent growth rates of bananas between SEA and southern California. That URL did not get me anywhere close to the list you mentioned, and I am not prepared to spend a large amount of time to research your debating point. I am afraid, that you have to get me a bit closer to the the proof of your assertion. - Fair enough? Best, Olaf |

Re: What root rot?
Here's a thread from July 2005 on the topic of maturation: http://www.bananas.org/f2/maturation-10.html#post29

Re: What root rot?
Okay, Richard, I looked at that thread too. It talks about (large) differences of
maturation of fruit after bloom or after development of first fingers, depending on species. It neither supports nor disproves your assertion, that bananas ripen much faster in SEA than in California. Until you can proof me differently, I still maintain, that the growth rate depends on light, soil and temperature conditions much more than on location, and location has certainly no impact on susceptibility to root rot. I state it again: Bananas with healthy green leaves will not suffer from root rot, when in a pot with a drainage hole in the bottom (and of course as long as that pot does not sit in a trough full of water). :) But even the latter might not be a problem, if the water in that trough is renewed frequently (aeration). :) |
Re: What root rot?
Olaf,
When Tony and I first joined this site several years ago, root rot was the biggest problem we noticed among novice gardeners. Also, I noticed it among some of my customers who purchased bananas from me here in San Diego. The main problem was with novice indoor gardeners. As you are no doubt aware, the humidity in a house is much lower than outdoors. This in turn causes the top layer of soil in a pot to dry out quickly. A novice gardener will notice this, and thinking the plant needs water will give the plant a drink. If they do this several times a week under the lower light input of indoors with a moisture retention soil, root rot is going to happen. Now, since you are an experienced indoor gardener I doubt it will ever happen to you. The folks from southern CA on this site will attest to 18 month maturation times. However, as Gabe pointed out 3 times in this paragraph, under tropical conditions that standard time is 9 months or less: Quote:
As for the chart from Biodiversity International, I recall it was the subject of discussion in a thread here -- and one of the remarkable things on the list was a banana that is named for the number of days it matures. I'm sure someone will dig it up sooner or later. |

There is no way, that you can equal the sogginess of the plants in the original picture by just watering a few times every week, even by watering every day. I have that photo as evidence. Where is yours, other than speculation on the "inexperience" of indoor gardeners, which only serves to propagate the popanz of root rot, which is impressed onto every newcomer to this forum, and which does not exist under the conditions, I have specified herein. I do not turn back, if a black cat crosses my intended pass, but I do not walk under ladders, if someone works above, who might drop a tool or implement on my head. That makes sense, because a wrench falling on my head hurts. Being scared of root rot in a plant, which appears perfectly fine with "wet feet" does not make sense, and justifying that fear with contrived speculation about country of location does not make sense either Quote:
makes sense, but has zilch to do with root rot. Here the growth period is not even long enough to bring any banana to bloom, but we still do not experience root rot. Though I have never stuck a banana's "feet" into water, while it was "beheaded". :ha: Olaf PS: Frankly I have repeated myself more often, than I am comfortable with, and unless you come up with some solid evidence on root rot, other than 'hearsay' and speculation, I am bowing out of this discussion |
