lummy

I am growing 4 varieties ,dwarf cavendish, blue java, dwarf orinoco, and a mystery plant that the guy said was FHIA. I also live in the bay area, East Bay to be exact. I've had the orinoco and mystery plant for a little over 2 years now. My oldest mystery plant and orinoco flowered this summer and we grown exclusively in large pots.
The cavendish are the only ones that have problems with our winters. I'll bring them inside if we get a freeze warning, but I don't do anything to the other plants. The biggest issue I've had with them is getting blown over during windy days. Their pseudostems are 6-8ft tall. Oh yeah, I also drill holes in the bottom of the pots so the water drains out

I bought my blue java from a guy in Sacramento. His established plants' pseudostems were at least 15ft tall. I have 2 and I just put them in the ground after being in a pot for a year. If yours are the same, I would be worried that it would fall over
