How to Grow Melic Grass
Melica uniflora
Melic grass is a graceful, shade-tolerant grass that thrives in woodland gardens and dappled light. Plant in spring or autumn in well-drained, humus-rich soil, spacing plants 25-35 cm apart. It produces slender arching stems bearing delicate nodding seed heads from late spring into summer that catch the light beautifully. Unlike most ornamental grasses, it actively welcomes shade — perfect under deciduous trees. Cut back dead foliage in late February or early March before new growth appears. Divide congested clumps every three to four years in spring to keep plants vigorous.
Yearly Lifecycle
Care Essentials
Rarely needed. A light mulch of leaf mould or garden compost in autumn is sufficient. Avoid feeding with nitrogen-rich fertilisers — this produces rank, floppy growth and reduces the delicate arching habit.
Watch For
- Slugs on young spring shoots
- Crown rot in heavy, waterlogged soils
- Overcrowding — divide every 3-4 years

Care Requirements
Light
Partial shade to full shade; tolerates sun in cool, moist conditions
Melic grass is one of very few ornamental grasses that genuinely thrives in shade. It grows happily in dappled light under deciduous trees, in north-facing borders, or in any position with two to four hours of sun. Full sun is tolerated only in cool climates with consistently moist soil — in hot, dry spots it browns and dies back in midsummer.
Watering
Moderate moisture; keep soil from drying out completely
Water new plantings regularly during the first growing season. Once established, melic grass tolerates short dry spells but dislikes prolonged drought. In shadier positions under tree canopies, natural rainfall is usually sufficient. Avoid waterlogged soil which causes crown rot.
Fertilizing
No feeding required; lean to moderate soil preferred
Melic grass needs no supplemental feeding. A light autumn mulch of leaf mould or garden compost is all it needs, mimicking the humus-rich woodland floor it naturally inhabits. Rich feeding produces floppy, lax growth that loses the characteristic delicate arching habit.
Pruning
Cut back to ground level in late February before new growth emerges
Leave all foliage and seed stems standing through winter for ornamental value and crown protection. In late February or early March, cut everything back to near ground level using garden shears before new shoots appear. Divide congested clumps in spring every three to four years.
Spacing
25-35 cm apart; plant in drifts for best effect
Individual plants form neat clumps 25-30 cm across. For the most beautiful effect, plant in groups of five or more at 25-35 cm centres to create a flowing, shimmering carpet of nodding seed heads. Works well as ground cover under trees.
Support
No support needed
The slender arching stems are self-supporting. In very exposed windy sites, some bowing may occur, but this is part of its natural grace and no staking is needed.
Growing Tips
Embrace the shade
Unlike most ornamental grasses, melic grass thrives in dappled shade and partial sun. Plant it under deciduous trees or in shaded borders where other grasses struggle.
Leave seed heads for winter interest
The delicate nodding spikelets are at their most beautiful in winter when frosted or backlit. Leave them standing until late February when you cut back for fresh growth.
Divide every 3-4 years
Lift and divide congested clumps in early spring. Replant vigorous outer sections and discard the woody centre. Division keeps plants flowering well and prevents die-back at the crown.
Use leaf mould, not fertiliser
A mulch of leaf mould or well-rotted compost in autumn mimics the woodland floor it comes from. Avoid nitrogen-rich feeds which produce lush, floppy growth at the expense of the characteristic airy habit.
