Heath-grass (Danthonia decumbens)

Heath-grass

Also known as: Decumbent heathgrass

Heath-grass (Danthonia decumbens) is a low-growing grass commonly found in heathlands and pastures. This grass is similar to purple moor grass, Molina caerulea, but can be differentiated because it has longer hairs at the end of the leafstalk. Though it is not classified as invasive, it is becoming a threat in the state of Oregon, where it is displacing native vegetation that the threatened Oregon Silverspot Butterfly (Speyeria zerene hippolyta) depends on for food.

Water: Heath-grass prefers moderate rainfall and a balanced watering routine. It should be watered weekly for optimal health. Adapted to various climate zones, heath-grass can endure periods of rain, avoiding overwatering issues typical in outdoor environments.

Fertilize: For optimal care of heath-grass, apply a light layer of mulch or compost annually to enhance nutrient content. Fertilize in spring to support growth post-dormancy, but avoid over-fertilization. Wear gloves when distributing to prevent foliage damage and disease transmission.

Pruning: Heath-grass features a grass-like look and thrives in heathlands, needing minimal pruning. Prune in early spring to remove dead foliage, encourage growth, maintain tidiness, and enhance air circulation to prevent diseases. Regular pruning boosts aesthetic appeal and overall vitality. Consult reputable sources for more care tips.

Propagation: Heath-grass is a perennial grass that tolerates poor soils and high altitudes. Propagation through clump division in spring ensures successful establishment. Each section should have enough roots and be replanted promptly. Regular watering is needed, but avoid excess moisture to prevent root rot.
