ðą How to Care for Mexican feather grass to Prevent Grey Mould?
ð§ How to Water
Water regularly during the first year to encourage root establishment. Once established, reduce to a minimum: occasional watering is sufficient during prolonged droughts. Excess water or poorly drained soil promotes root rot.
âïļ Lighting
Plant in full sun, with at least 6 hours of direct sunlight per day, to maintain its compact fountain-like habit and encourage abundant flowering. In partial shade, the foliage becomes floppier and flowers less.
ðŠī Ideal Soil
Prefer poor to moderately fertile and, above all, well-drained soil: sand, gravel, chalk, clay, or loam are suitable as long as water does not stagnate. Avoid nitrogen-rich soils, which promote messy foliage prone to lodging.
