Hi Justin,

interesting post. Let us first get the desert out of the way: Areas, with 250 mm annual
rainfall (precipitation) or less are classified as desert. That includes most, if not all of
the Antarctica. I let you figure out which hardiness zone that is.

Here in Penticton temperatures up to 105^F have been measured. We reach 100^F
most years. In Osoyoos, 40 miles south of here and still within the Sonoran Desert
temperatures of 109^F have been measured. But that is not the hottest place in
Canada. Lytton, BC, in the Frazer Canon, temperatures have gone as high as 112^F,
although it is not located within any desert. Some define ‘desert’ by vegetation. By that
measure the Sonoran is creeping northward. Antelope brush (also grease wood) has
now reached the south shore of Skaha Lake, just 8 miles south from my home, one of
the two lakes, which squeeze Penticton from north and south, thereby mitigating some
of the climate extremes, which are inherent to desert and semi-arid regions.

Hardiness zones on the other hand are governed by the expected min. temperatures
(here 5^F)

Now to the bananas with roots in water:
Your photo appears to corroborate, pending your confirmation, a quiet theory of mine,
that the rot in waterlogged banana roots has a lot more to do with oxygen content of the
water than with temperatures or growth rates. Look at the photo, with which I started
this thread: Lots of water surface exposed to rain and its oxygen enhancing splashing.

Vicky here my water bananas has constantly or often water
running through her pond (?), keeping up the oxygen levels. Vicky, please help me out
on this one.

The pond here: Growing a banana tree in a pond has a relatively large water
surface, onto which rain can splash and it may even be augmented by something else
creating a bit of turbulence.

Your pond, on the other hand, appears, judging form your photo to be quite serene and
have many other plants competing for oxygen crowding the surface. Again, Justin, I
have to ask you to help me out and tell me, if this is the case. If it is, a solution might be,
to add any water to the pond from some height to create some splash.

Best,
Olaf
PS I will ask Vicky now by PM, to tell us more about the conditions in her pond
