Harvest Tips
Night-blooming cereus is grown for flowers rather than harvest. Flowers open between 8 PM and midnight and close by dawn. To enjoy blooms, prepare a viewing space the evening before anticipated flowering. Berries can be collected after flowers fade if seeds are desired; they turn red when ripe (3-4 months after flowering).
