Care
Watering
Bearded oat is very drought tolerant once established. Water moderately during spring growth, then gradually reduce in summer. In Mediterranean climates, no additional watering is generally needed after establishment.
Exposure and Light
Install this grass in full sun for optimal growth and generous flowering. It tolerates bright conditions but dislikes dense shade. Prolonged exposure to intense sun intensifies the golden appearance of its spikelets.
Soil and Preparation
Bearded oat thrives in well-drained soils, even poor or stony ones. Avoid overly wet or compacted soils that promote rot. Light, chalky or sandy soil suits this hardy species perfectly.
Pruning and Cutting
Let the plant develop naturally to appreciate its airy silhouette and bearded spikelets. After flowering, you can leave the dried stems in place for autumn ornament, then cut back to ground level in late winter before new growth.
Fertilizer
Bearded oat needs virtually no fertilizer in ordinary soils. In very poor soil, a light application in spring is sufficient. Excess nutrients encourage lodging and diminish the plant's hardy character.
Health and Prevention
This grass is little susceptible to diseases. Excessive moisture in winter or spring can occasionally promote rot. Ensure excellent drainage and avoid accumulating organic debris to prevent any issues.
Did you know?
Bearded oat owes its scientific name barbata to its spikelets equipped with a long and distinctive awn, resembling a fine beard. Native to the Near East and Mediterranean, this grass has coevolved with cereal crops since antiquity and once served as livestock feed. It remains an excellent ecological choice for restoring Mediterranean dry grasslands.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
