About this plant
A hearty plant that looks just like grass. It makes a clump of long leaves that may stand upright or arch. There are small flower spikes in summer but these are not ornamental. It is a useful plant for cooking, the hard leaf base being used to make 'sereh' powder. Tea can be made from the leaves. It has medicinal properties and is used for digestive problems and treat other ailments such as ringworm. It is used to make vitamin A and in the preparation of soap. It can be grown outside in the summer but needs to be brought into a warm greenhouse for the winter.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
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 · Planting
Repot yearly
Repot yearly if grown in a pot. Move it to a slightly larger pot with drainage holes. Some of the old compost can be shaken away, but don't disturb the roots too much.
Be careful to ensure the roots are spread out in the new pot, and that the plant is sitting on compost and not an air pocket. Firm the soil gently, and make sure that the plant sits at the same level above the soil as it did previously.
Spring - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
Winter
Winter · Outdoors
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.
