It prefers full to partial sun exposure and cooler temperatures, typically found close to coastal areas. The plant is best propagated through seed sowing, which can be done in early spring or fall. Seeds should be placed on the soil surface and lightly covered with soil. Young seedlings can be transplanted when they have developed their second or third leaf sets and are about 2 inches tall.
Watering needs
Deschampsia cespitosa (L.) Beauv. var. maritima Vasey is a drought-tolerant species that needs minimal watering. Once established, the plant can withstand long periods of drought. However, optimal growth and flowering will be achieved with regular watering during the growing season. Watering should be done when the top inch of soil is dry to the touch. Water should be applied to the soil around the plant base and not on the foliage, which can lead to diseases.
Fertilization
Deschampsia cespitosa (L.) Beauv. var. maritima Vasey does not require heavy fertilization. Organic matter, such as compost, can be added to the soil during planting and periodically as a top dressing to improve soil quality. A slow-release balanced fertilizer can be applied once a year in early spring to boost growth and flowering. The fertilizer should be applied at the base of the plant and watered immediately to avoid burning the roots.
Pruning
Deschampsia cespitosa (L.) Beauv. var. maritima Vasey does not require significant pruning, and it is best to avoid it whenever possible. The plant has an upright and clump-forming habit, and removing too much foliage can impact its aesthetic value. However, dead, damaged, or diseased foliage should be removed promptly to prevent further spread. Seed heads can be left on the plant into late fall or early winter to provide winter interest and food for wildlife.
Propagation of Deschampsia cespitosa (L.) Beauv. var. maritima Vasey
Deschampsia cespitosa (L.) Beauv. var. maritima Vasey, commonly known as Tufted hairgrass, can be propagated by seeds, division, or tissue culture.
Seed Propagation
The seeds of D. cespitosa can be collected in late summer or early fall and sown immediately or stored for later use. It is recommended to stratify the seeds in moist sand at 4°C (39°F) for 30-60 days prior to sowing to break dormancy. The seeds can be sown in pots or trays filled with a well-draining medium and covered lightly with soil. The pots or trays should be kept moist and placed in a warm, bright location. The seeds can take 2-4 weeks to germinate.
Division Propagation
D. cespitosa can be propagated through division, particularly in the spring or early fall. The clump can be lifted with a garden fork or spade and divided into smaller portions, ensuring that each division has a healthy root system. The new divisions can be planted immediately in a location with well-draining soil and adequate moisture.
Tissue Culture Propagation
Tissue culture propagation is a more advanced but effective means of propagating D. cespitosa. This involves taking small sections of the plant and propagating them in a laboratory under sterile conditions. The sections are allowed to grow in test tubes containing nutrient media until they form roots and shoots. The resulting plantlets are then transferred to soil and grown in a greenhouse or nursery until they are large enough to be planted outdoors.
