Growing Japanese forest grass 'Aureola' in a pot

Hakonechloa macra 'Aureola' has a moderate water need and dislikes drying out completely. Water regularly during the growing season, especially in prolonged dry spells, aiming to keep the soil consistently moist but not waterlogged. Plants in full shade typically need less frequent watering than those in brighter partial shade. Container-grown specimens dry out faster and may need watering several times a week in summer. Reduce watering from autumn as growth slows, but don't allow the soil to become bone-dry over winter. Feed in April and May to support the flush of fresh foliage. Apply a balanced slow-release granular fertiliser such as blood, fish and bone around the base of the plant, following packet rates. Alternatively, use a general-purpose liquid feed every four to six weeks during the growing season. Avoid high-nitrogen feeds that promote lush growth at the expense of the plant's characteristic golden colouring. A spring top-up of organic mulch also provides gentle, sustained nutrition. This grass is fully hardy in zones 5–9 and needs no special winter protection in temperate European gardens. The crown may suffer in very wet, cold soil, so ensure drainage is adequate at planting time. Slugs and snails occasionally nibble young spring shoots; use organic pellets or barriers if damage is severe. The plant is otherwise remarkably pest- and disease-free. Refresh the mulch layer each spring to suppress weeds and conserve moisture. Every three to four years, consider lifting and dividing congested clumps in spring to maintain vigour—replant healthy outer sections and discard the woody centre.
