Watering
Water sparingly during extended dry periods; allow soil to fully dry between waterings
Fertilization
No regular fertilization required. Low-nutrient soil supports natural growth; avoid synthetic fertilizers
Crushed eggshell powder：Sprinkle finely crushed eggshells on soil surface; no dilution needed, as it slowly releases calcium over timePruning
- Trim back dead foliage in late autumn to maintain dune habitat structure
- Avoid excessive pruning to preserve seed heads for natural propagation
- Remove competing invasive plants to prevent crowding of native dune vegetation
