Water: Blue curls thrives in moderate hydration, preferring consistent moisture without waterlogging. Water it weekly for balance. As an outdoor plant in temperate regions, its growth cycle depends on water availability, making efficient rain capture crucial for seasonal development.
Fertilize: To support blue curls's growth, apply a balanced fertilizer monthly in spring and summer. In fall and winter, switch to high-nitrogen fertilizer every 6-8 weeks. Water after fertilizing to aid absorption. For new or re-potted blue curls, wait 4-6 weeks before fertilizing to avoid shock.
Pruning: Blue curls features dense clusters of blue flowers and requires light pruning in early to late spring. Remove dead stems and spent flowers to promote growth and enhance appearance. Pruning improves airflow, reduces disease risk, and supports vigorous development.
Propagation: Blue curls, native to Texas, prefers varied soil types and light for germination. Surface sow tiny seeds, mist to keep soil moist. Post-germination, water moderately and provide full sun to partial shade, using well-draining soil for healthy growth and annual coiled blooms.
