I did a little research since posting this yesterday and just in case someone else is having this problem one possible explanation for the trees falling is that they may be water sprouts. I haven't paid much attention to the bananas this year, so maybe some of the water sprouts grew up and are blooming now. Supposedly they are not as well attached as the sword suckers. Here's a picture of the two mats along with everything I just removed from them including the blossom ends.

I decided to give them some fertilizer and horse manure. Not sure if that's the right thing, but it's done.

There are some good tips for propping up your plants.

thanks wildforager,

That article was great. I guess this is a common problem and I need to get lots of PVC!!

Great Banana plants!
How did you post the picture?
Thanks,

Wow. My dwarf cavendish gets to half that size and grows bananas that are in smaller amounts. I live on a rocky landfill in west broward. I guess that doesn't let my cavendish grow as big as yours.
Just stake your banana plants to help them support the weight of the bananas.
