Planting Conditions

Calamagrostis, or feather reed grass, thrives in well-drained soil and prefers full sun to partial shade. Position it where it can receive at least 6 hours of sunlight daily. Prepare the planting area by loosening the soil and incorporating organic matter like compost. Plant the grass at the same depth it was in the container, ensuring the crown is level with the soil surface. Gently firm the soil around the roots and water thoroughly after planting to settle the soil. Mulch around the plant to retain moisture and suppress weeds, ensuring good air circulation around the base.

Watering & Feeding

Generally, Calamagrostis, like other ornamental grasses, typically prefers moderate watering during its establishment phase, allowing the soil to dry out slightly between waterings to avoid waterlogged conditions. Once established, it often requires minimal additional watering unless experiencing prolonged dry spells. As for feeding, a balanced fertiliser in Spring can support healthy growth, but ornamental grasses like Calamagrostis generally thrive without heavy feeding. It's advisable to follow specific guidelines based on soil type, climate, and the plant's overall health and growth.

General Care

Calamagrostis is known for being relatively low-maintenance. It requires minimal pruning beyond removing dead or damaged foliage in early Spring before new growth emerges. Disease and pest issues are typically uncommon, as these grasses are resilient and sturdy. Providing well-drained soil and adequate sunlight are key to maintaining their health. Regular monitoring for any signs of stress or discolouration can help address any potential issues promptly, ensuring the continued vigour and attractiveness of the plant your garden.
