Containment
 

I'm new to growing bananas and just got my second plant. The space I'm thinking of planting it is a bed that's fairly tight in between two concrete patios. I'm hoping there is a way to keep the banana from spreading laterally and invading the rest of the bed. Just how invasive are the corms and does it depend on the type of banana? Its a Red Cavendish plant.

Looking at your pic (I can barely see) it looks like an ensete Maurelii not a musa so won't send up any pups.

Re: Containment
 

The varieties that make pups (all the edible cultivars) will spread, but they can be contained in a relatively small area if you are committed to regularly removing pups and occasionally pruning the corm. If you search through Richard's posts, you may find some examples because he grows them in a narrow bed. Some varieties will be more work than others because they grow faster and pup faster.

I dont think most Musa would be too much of an issue as far as invasivness goes, except for maybe The Itinerans group, and a few others. Still waiting for mine to become invasive darn it lol.

Bananas do spread however you will be able to keep them in check by culling unwanted new plants......they do not spread that fast and you'll will be able to keep up.:08:

Due to your climate and prolonged heat there is a good chance your plants will cook between two concrete slabs; if your air temp is 105 degrees the slabs could be 130+ thus making a poor environment for the roots.:(

Same way with containers/dark stained decks,unless they are in the shade they will be 25+ degrees than the air temp which is also too hot for roots to thrive:(

Before you plant you might want to see how hot your new area will get.
