The popularity of banana plants is growing, and they are now popular in countries where they don’t naturally grow. This is no surprise because this group of tropical plants are beautiful.
Banana trees are one of the more common trees that come to mind when one is dreaming of the tropics. However, did you know that they are not really trees? They are actually the world’s largest herbs. Still, due to their size and appearance they are they have become commonly known and thought of as banana “trees”.
The banana is in the same order of plants as the Strelitzia, Ravenala and Canna genera which you may be familiar with. The scientific name for the banana genus is Musa. This article provides an overview of the basics of caring for banana plants. Of course, the care required for different species may vary slightly.
First let us get familiar with the morphology of this plant. Banana plants have a pseudostem, and new leaves will be pushed up from the middle of this. These new leaves are rolled up, and they will unroll when the whole leaf has emerged.
Most of the older leaves on a banana plant are torn because the leaves are very thin, and even the wind can blow holes in them. Banana plants have rhizomes, and from these many new shoots appear. You can cut these off the ‘mother plant’ and can be potted on.
A frequently asked question is “Will there be real bananas on this tree?”. After three or four years a banana tree will flower and then you will get bananas that you can eat
The biggest challenge with this plant, when not growing it in the tropics, is how to protect it in winter.
Warmth is necessary for optimal growth. There are also banana plants available that will grow in the cold, but below five degrees they will also stop growing. Below minus two degrees the leaves will die but the roots will still be alive.
Popular species for cold climates:
Musa basjoo: can survive until -20°C
Musa sikkimensis: can survive until -15°C
Musella lasiocarpa: can survive until -5°C
Light A warm environment is not all that is required – banana plants also need a lot of light. If you have a banana indoors you need to make sure that it is near the window, but avoid direct sunlight because this will burn the leaves.
Of course after heat and light you need to consider water – banana plants need lots of water. On hot summer days they can require up to 10 liters of water. But be careful that the roots aren’t sitting in water, because these plants are infamous for developing root rot. During the colder season, less water is necessary.
Banana plants can grow very fast, especially if you fertilize them correctly. It’s almost impossible to give too much fertilizer to a banana, but of course in the cold months the fertilizer must be minimized to discourage growth.
You don’t need to prune bananas but for aesthetic reasons you can remove the old leaves. You can also remove the plantlet If your banana has frost damage, you can cut off the damaged part of the trunk and most of the time it will grow again. When you cut away the damage you must remove a large part of the trunk to encourage regrowth.
Basically, banana plants are not very susceptible to pests or diseases. Most problems will arise in the winter time. The most common issues are spider mites, aphids or root rot from soil that is too wet. For the first two issues you should use the most appropriate treatment as soon as possible. For example, a suitable pest control product. Rotting can only be prevented by ensuring a dry root ball. It is best to cut away any rotten parts before allowing the root ball to dry out.
