You can get fruit in a pot, but it's more work. Could you cover one up if it was going to get cold? that would be a lot easier, I'd think. Maybe with a light bulb or heater under the covering?You are so lucky, I'd definitely trade you zones!

Yeah I suppose I could just cover it up when it gets cold and I suppose that isn't much more effort than bringing in a 50lb pot everynight in the winter. I was mainly worried about getting the leaves covered especially once the plants get to a good height. Also is there any fire danger with the light bulb under a cover? Leaving the banana in the pot just "seems" easier though I suppose there are plusses and cons to both of them.

I assume the main problem with keeping it in the pot will be enough water and nutrients?

But yeah, speaking of zones, lately I've actually been considering planning a move to S. Florida long-term. I'm such a huge fan of tropical plants it'd be great living somewhere that was consistently warmer through the year and more humid! I know that might seem silly compared to where you live but I feel like I have to baby these plants. I've been misting the leaves and such to try to keep the humidity up now that it's getting hot here and our winters are still colder than other climates.

yes bananas do fruit in pots,ive seen it several times

I have three potted plants, all in south facing locations. They do very well, the oldest is two years. I got them from a 6' high mother plant that bears fruit. I assume that in time mine will bear fruit as well. I water them when the pot feels light, and the top 2-3" of soil is dry. I have noticed when the soil is drying out, the tips of the leaves are dripping clear fluid. Does anyone have any info on why this happens?
Thanks
