base has shrivelled but the new growth is progressing
I notice two things:

1. No suckers.
2. Compared to your first photo, almost all of the old leaves have died.

My plant is like yours in those respects. But, I know that my older leaves are dying sooner than they should. Does anybody know the cause?

As an experiment, I am thinking about spraying my plant with 250 ppm silver nitrate because it is an ethylene antagonist and ethylene promotes leaf abscission. See

Also, I have a small fortune in silver nitrate gathering dust in my basement that I haven't used in 45 years. Who else but me hoards that kind of stuff? Ha, ha, ha, the advantages of being me.

Done!





The grey color of the solution is worrisome. I will have to investigate.

The "worrisome" grey color was from a precipitate caused by a chemical reaction with impurities in my tap water which is from Lake Michigan. I replaced it with distilled water and resprayed today. Incidentally, as a surfactant, I used Triton X-100 because it is a stronger surfactant than Tween 20. Even so, it takes at least 250 ppm Triton X-100 to prevent beading on banana foliage.

BTW, silver nitrate is not my best choice for ethylene antagonists. I am only using it for convenience. If I could afford it, I would use aminoethoxyvinylglycine (AVG), the active ingredient in the commercial PGRs, ReTain and PinCor. See

Maybe, AVG can be used to increase the size of banana fruit.
