I want to thank everyone for their wonderful advice. In a couple of weeks I’ll be repotting in a much larger pot and moving outside for full sun all day. Updated picture attached.

Lots of sun. They are grown in full sun in Hawai'i. They are delicious-my favorite bananas. Please keep us posted.

Looks dark in that spot. If you do get a bigger pot, get rollers for it. You will be more likely to move it to better spots.

I agree with what @Glennlab said. Get a bigger pot and leave it in full sun as much as you can.
I knew a guy that removed his banana tree from the ground before freezing times and put it back once weather was safe. He was successful getting thing fruits. I haven't done that yet.

Lots of sun larger pot enriched soil use recommended fertilizer and watering....my tree took two years b4 bearing bananas

First you need a larger pot. 10-20 gallons. They are biennial so it takes 2 years to get fruit. Keep the soil moist, full sun. They reproduce by putting out suckers, these can either be left on the trunk or transplanted for more plants. If it is not producing suckers within 6-9 months, it is not happy. When it flowers you will need to move it outdoors for pollination, wasps pollinate bananas, once the stalk has finished blooming and the bananas are roughly a uniform size, cut the stalk off and trim the plant level with the ground. The bananas will ripen if hung. If you leave them on the plant they will wither and become inedible.

Depends on the weather where you live . Saw a couple on here , who lived i Florida , seemed tto be doing a great job with them , but they're no longer posting here .
