Musa basjoo is a herbaceous perennial with trunk-like pseudostems growing to around 2–2.5 m (6.6–8.2 ft), with a crown of mid-green leaves growing up to 2 m (6.6 ft) long and 70 cm (28 in) wide when mature. The species produces male and female flowers on the same inflorescence which may extend for over 1 m (3.3 ft). The banana fruit formed are yellow-green, around 5–10 cm (2.0–3.9 in) long and 2–3 cm (0.79–1.18 in) broad; they are inedible, with sparse white pulp and many black seeds.
Watering requirements for banana plants can vary slightly depending on whether you choose to plant them in the ground or in a container on your patio or porch. These guidelines will help get your banana tree off to a great start.
When fertilizing a mature banana plant, use 1 ½ pounds (680 g.) of 8-10-10 per month; for dwarf indoor plants, use half that amount. Dig this amount in around the plant and allow it to dissolve each time the plant is watered. Or you can give the banana a lighter application of fertilizer each time it is watered.
Cut the stalk with a clean and sharp knife about ½ to 1 inch from the trunk. Regular pruning will allow your banana plant to remain looking lush. Make sure you have waited until you have harvested any fruit and until your plant has flowered before you prune the stem.
