Most banana
trees are hardy in
zones 8-10 and would not survive the winter even with a mulch. They should be lifted in the fall, potted, and brought in the house. Indoors they should be grown in soil-based potting mix in full light with shade from hot sun. From
spring to summer, water freely and apply a balanced liquid fertilizer monthly. Keep the soil just moist in winter.
go to top of your page in search Garden helper type in banana
tree care. The leaves on mine turn brown then it puts on new leaves I keep it moist all the time will try and get a phot later to post here.
Hope this helps
