Black cosmos are generally easy to care for, thriving in well-drained soil and requiring full sun exposure to flourish. Special care should be paid to avoiding waterlogged conditions, as black cosmos is sensitive to root rot. Deadheading spent flowers encourages continuous blooming and maintains the plant's vitality.
