About this plant
This herbaceous plant can reach 3m (10ft) height. It has very large, exotic-looking, oblong leaves at the top of the stem. The leaves are paddle-shaped with a large, central vein. The leaves are prone to splitting if subjected to wind and then tatter to give an almost fringed appearance. It does produce bananas but these are inedible and coloured green. The stalk is interesting for its beige, papery, peeling appearance.

Spring
Spring-Autumn · Indoors
Feed with houseplant food monthly
Give the plant a balanced houseplant feed monthly while in growth.
Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.
Spring-Autumn · Indoors
Water regularly during growth
Water regularly while in growth.
Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.
Spring-Autumn · Outdoors
Feed a general fertiliser
Give a general purpose feed two or three times during the growing season, preferably not within a month of its end so the plant isn't encouraged to make fresh young growth.
Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Winter
Winter · Indoors
Water sparingly during dormancy
In its dormant period give very little water, keeping the soil barely moist. Dormancy is likely to be during the winter and the plant recommences growth in early to mid spring.
When a plant enters dormancy the leaves fade, go yellow and then brown. Eventually the whole plant may 'disappear' or unadorned stems may remain.
Winter · Planting
Divide plant to maintain size every 5 years
Rhizomes can be divided, or clumps separated, discarding any weak or diseased parts and replanting the remainder. The rhizome sits below the soil.
Planting & general
Compost · Planting
Loam based houseplant compost for repotting
Buy container or house plant compost that is loam based if possible (i.e. is based on John Innes compost number 2 or 3. This contains more fertiliser and is better suited to established plants.
John Innes no. 1 has the lowest level of fertiliser and is used for seedlings and young plants, so is generally used where plants will be 'potted on' after a number of weeks.
Indoor temperature · Planting
5C minimum temperature
This plant requires a minimum temperature of 5 Centigrade.
Indoor plant · Planting
Position in a bright spot, no direct sun
Give this a bright position away from the direct sun, especially direct sun at the height of the day. (Direct sunshine is too hot and can burn the leaves.) Move the plant to a brighter position in the room during winter and early spring.
