Water regularly to promote rapid growth. They should be protected from wind so the leaves don't shred. Bananas will bloom two to five years after planting. Plants will die down to the roots after flowering. It's possible to grow new plants from the shoots at the crown, but it's easier to discard them and buy new nursery stock.
Bananas die back in cold winters but grow again in spring.
They make excellent container plants to grow outdoors in summer and indoors in winter. You can move your plants in spring just before they begin active new growth. To grow bananas inside, choose dwarf varieties such as 'Jamaica Red'. To pot up your banana, use a loose, light soil mixture containing perlite, sand and peat moss. Add soil so the neck of the corm is just covered and the top of the corm is exposed.
