Water: Largeflower phacelia thrives in moist conditions and requires consistent weekly watering to maintain lush growth. It prefers well-draining soil that retains moisture, essential for preventing root rot and supporting healthy growth cycles, reflecting its adaptation to environments with regular rainfall.

Water before application and adjust frequency in winter. A consistent fertilization routine enhances the vitality of largeflower phacelia.
