What Kind of Roots Do Dwarf Banana Trees Have?

Root Structure

• Dwarf banana plants grow from a rhizome. Botanically speaking, rhizomes aren't roots, but are actually an extension of the stem that grows horizontally under the soil. From this rhizome, hundreds of fibrous roots reach out to hold the plant in place, absorb nutrients and take in water.

Bananas in Pots

• With their horizontal rhizome and extensive roots, dwarf bananas typically need a pot that is wide and deep. A large container allows the rhizome and roots to grow, which leads to a larger banana tree. Indoors, keep the plant in a bright area, preferably with high humidity. When the weather warms, move the plant outside to a place where it can receive direct morning and evening sun and dappled afternoon sun.

Soil and Water

• Your banana needs loose, fertile soil. For optimal growth and fruit production, the soil needs to have a pH range of 5.5 to 7.0. Most store-bought potting soils will meet this range. Water your banana often enough to keep the soil from ever becoming dry, but not so much that the soil has standing water. Feed your banana with a high potassium fertilizer every two to three weeks.

Propagating Your Banana

• Properly cared for, your banana will eventually outgrow its pot. You can repot it or you can control the size of the tree by cutting off end pieces of the rhizome. These pieces can then be planted in a smaller pot. With the same care you provide the parent plant, these cuttings will eventually sprout and make ideal gifts for other banana lovers.
