What root rot?
Time and again is the concern about root rot due to over-watering brought up in
this forum. I have stated several times, that this concern is in most cases completely
unwarranted, citing the example of all those banana plants at the edges of rice fields
on ground no more than 6 to 8 inches above standing water: If your banana has green
leaves and your pot has drain holes at the bottom, you are not getting root rot, no
matter how much you water.
Last night I went through some old photos and found this one:

It is a bad one, shot almost three years ago from a travelling vehicle, without image
stabilizer in that old camera, but I believe, that it still shows clearly that the roots of
those bananas must be submerged in standing water. If you look closely you can spot
the water between the PSs on the other side of that skimpy ridge. On Thursday I will
head to Vietnam again, only this time we do not intent to travel to the northern part
of the country, where most of the rice fields are. I still hope to get a better picture
showing banana plants with the roots in water.
Until then, while you have green leaves on your plants your only worry about too much
water should be leaching all the nutrients out of your soil.
