When to plant Japanese forest grass 'Aureola'?

Hakonechloa macra 'Aureola' thrives in partial to full shade, making it ideal for brightening darker corners of the garden where many other ornamental grasses struggle. Choose a sheltered spot protected from strong winds, which can scorch the delicate golden foliage. The plant performs best in moisture-retentive loam or sandy soil enriched with organic matter. Avoid heavy clay that stays waterlogged, as this can lead to root rot. Plant in March, April or May for spring planting, or in September and October for autumn establishment. Spring planting is generally preferable in colder gardens, giving the roots a full growing season to settle before winter. Prepare the soil by digging in well-rotted compost or leaf mould to improve both drainage and moisture retention. Dig a hole slightly larger than the root ball and plant at the same depth the grass was growing in its pot—burying the crown too deeply can cause rotting. Space plants 45 cm apart to allow for their spreading habit; mature clumps will reach 40–60 cm across. After planting, firm the soil gently around the roots and water thoroughly to eliminate air pockets. Apply a 5 cm layer of organic mulch such as composted bark around (but not touching) the base to conserve moisture and suppress weeds. Keep the soil consistently moist during the first growing season while the root system establishes. In containers, use a loam-based compost with added grit for drainage, and choose pots at least 30 cm wide to accommodate the spreading rhizomes.
