But now, after its 2nd winter/3rd summer in the ground, it is back to having some of its lower leaves go yellow and then, if I leave them on the plant long enough without trimming them off, they'll get dry brown patches.

I closely examined the pseudostem, and found that some of the old "boot jacks"--stubs of old leaves which I trimmed--- have gone pale beige, mushy, and stinky. There's a pic of that.

Also, read where Panama Disease shows "splits" in the pseudostem. I might have found a split. It's in one of the pics.IMG_0473.jpg

My main experience is with 2 other bananas ('Orinoco' and and ornamental flowering banana)in a different location. Neither ever had mushy/ stinky areas on the trunk, in the growing season. Neither ever had any issues, except they tended to be invasive.

So, here are a few pictures. What do y'all think? Does this look like it might be the dreaded Panama Disease? I'd really like to know, because we just bought a dwarf Cavendish and want to plant it nearby.

Thanks so much

The plants are just reacting to the shorter days and lower temps of fall.

Some plants will react quicker to the enviromental transition.

Many folks trim off older yellowing unsightly leaves as they appear.
Mine are in the transition now.
Looks normal to me.
