Step by step: plant maiden Grass
Maiden grass thrives in full sun and tolerates a range of soils, though it performs best in loam or clay that retains some moisture without becoming waterlogged. Choose a spot where the plant has room to reach its mature spread of 80–150 cm; these are substantial grasses that need space to show off their arching form. Plant in April or May once the soil has warmed and the risk of hard frost has passed. Dig a hole roughly twice the width of the root ball and about the same depth. Break up any compacted soil at the base to encourage root penetration, especially in heavy clay. If your soil is very poor or sandy, work in a few handfuls of well-rotted compost or manure to improve structure and moisture retention, but maiden grass isn't particularly fussy. Set the plant so the crown sits at the same level it was in the pot—planting too deep can lead to rot. Backfill with the excavated soil, firming gently as you go to eliminate air pockets. Space multiple plants about 100 cm apart to allow each clump to develop fully without crowding. Water thoroughly after planting to settle the roots, then keep the soil consistently moist for the first growing season while the grass establishes. A 5–8 cm layer of organic mulch around the base helps retain moisture and suppress weeds, but keep it a few centimetres clear of the crown itself. Staking is not necessary; maiden grass is sturdy once rooted, though young plants may flop slightly in their first summer before they bulk up.
