Trials of growing spinifex have included taking cuttings and the planting of whole seed heads. Cuttings – taken from healthy long growing shoots. Place the cutting in a coarse sand mix and water regularly. Roots may begin to appear after 2 weeks – cuttings can then be planted out into bags or root trainers.
