Water: Calthaleaf phacelia thrives with periodic moisture, preferring moderate hydration and consistent humidity. While drought-tolerant, it requires weekly watering to maintain balance. Cultivated outdoors, its water needs vary with the growing season to support optimal health and vigor.

Fertilize: For calthaleaf phacelia, apply balanced nutrition fertilizers monthly during growth, using half-strength for foliage enhancement. Benefits include robust growth and improved blooming. Water soil prior to application to aid absorption. Adjust fertilization frequency during dormancy, and take safety precautions like wearing gloves.

Pruning: Calthaleaf phacelia thrives with annual pruning in early to late spring. Remove dead stems to enhance growth and air circulation. Light trims maintain shape, while regular pruning promotes denser foliage and abundant blooms. Consult trusted horticultural sources for best practices.
