Outdoors on my deck in the summer, put them inside for the winter. They took a lot of fertilizer. Really easy to grow. You can find them online easy.Did you grow them indoors? Never done this, but interested!
I had a small banana tree in a giant container and would wheel it in for the winter. I think the 4th year it would have bore fruit but the 3rd year in...it took a light frost and was dead when I went to grab it. 3 years down the drain lol
