Planting & Care

Plant bulbs pointed tip up in well-drained soil in fall. Fertilize with bulb food at planting. Water well after planting. Allow foliage to die back naturally after blooming to feed the bulb for next year. Divide congested clumps immediately after flowering if needed. Deadhead before seeds disperse to prevent self-seeding.
