Re: Here's what happens if you don't remove pups
Hi Mark,
given your reply in which you quoted me as writing…:

So the June to August comparison is of doubtful importance

The response of banana growth rate to temperature is well documented in the literature. That is not to say that day length, or more generally, light exposure is not important, too.

…I do not think, that you even have read, what you quoted. So I will express it in a different way: In the tropics, which the bananas call home, the day/night cycle is very close to 12/12. In August you are much closer to that cycle and your bananas feel more like home and closer to conditions, which are anchored deeply in their genetic make-up.
Consequently they feel more comfortable, as far as natural light is concerned, in August through October than they do in June or December. If you could charm up some weather in the ^F 80s and 90s in natural light conditions, you would find similar growth spurts in February thru April.
Best,
Olaf
