Banana trees have shallow root systems that are made up of two main components: rhizomes and fibrous roots.
Rhizomes are thick, fleshy, root-like underground stems. They look a bit like ginger and are the central part of the plant. They spread through the soil horizontally and can easily exceed 10 feet in total network width. The plant’s visible stalks grow up above the soil from the rhizomes.
The fibrous “true” roots grow off the rhizomes. These are more conventional-looking thin, hair-like roots that absorb water and nutrients from the soil. They also provide physical support to the plant. The most delicate ones near the surface are referred to as “feeder roots,” while the thicker roots that grow deeper are called “anchor roots.”
Banana plant root basics
The banana plant’s root system is a complex, efficient structure that enables the plant’s growth, stability, and reproduction. The rhizome acts as the central storage hub, while the fibrous roots, anchor roots, and feeder roots collect resources and stabilize the whole plant. A healthy root system is keey to overall plant vigor.
Rhizome
The rhizome is the central underground stem of the banana plant. It is a thick, bulbous structure from which both roots and new baby stalks emerge. The rhizome of a banana plant looks a bit like fresh ginger root.
It stores nutrients and water for the plant’s later use. The rhizome also produces suckers, which can be transplanted and grow into new banana plants (vegetative reproduction). It is also a structural support for the plant.
Fibrous roots
Fibrous roots are thin, hair-like roots that come off of the rhizome. Their job is to take up water and nutrients (in solution with water) from the soil. Their large surface area maximizes uptake. The net-like structure helps hold to the soil, reducing erosion.
Feeder roots
Feeder roots are the thinnest, more delicate roots located near the soil surface. They are an extension of the fibrous root system adapted for efficient nutrient and water absorption. Feeder roots can quickly respond to changes in soil moisture and nutrient levels, adjusting their growth and activity to optimize absorption.
Anchor roots
Anchor roots are thicker and more robust than the main fibrous root system, and they also go deeper into the soil. They provide increased physical stability to the banana plant, helping it stand upright. This is key in windy conditions. Anchor roots can also access deep water and nutrients in a drought.
