About this plant
A lively little grass, often with bright variegated arching leaves in cream or gold. It's ideal for cheering up the front of a border and softening edges of a path or patio. It throws up inconspicuous brown flower spikes in summer which mingle with the bladed foliage. Growing to a height/spread of 30cm, it's a compact grass for small spaces, adding texture and shape all year round.

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 in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring-Autumn · Planting
Remove dead leaves
When leaves die they can carefully be detached or cut off at their base to improve the overall appearance of the plant. Be careful not to damage the main stems during this process.
Summer
Summer · Planting
Remove offsets to create new plants
Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.
Offsets may be used to replace an aged parent plant, to extend or establish a colony, or can be given away or sold.
