Plant Molinia in moist but well-drained soil in full sun or partial shade. It grows best in acidic to neutral conditions and appreciates a spot that doesn’t dry out in summer. Avoid very dry or overly rich soils, which can cause the plant to flop.

Once established, it's low maintenance. Cut back the dead foliage to ground level in late winter before new growth appears. Plants in more exposed garden settings may benefit from shelter from strong winds. It can be left to form natural clumps or divided every few years in spring if needed to maintain vigour.
