Yes cut off to leave 3-6 inches of the stem below the "head. allow to air dry (12 hours) apply 0.1% IBA (rooting hormone) stick in well drained soil. Keep soil moist not wet & out of direct sunlight & draft.
By the way take the remainder of stem cut into 12 inch sections. Lay on side cover about 1/2 of stem with moist soil. After 3-6 months will see small new plants along stem..... these can be seporated, into individual plants.
