Other Information:  Many cultural uses are ascribed to this plant species. They can be left in a pot for many years due to their slow growing nature. Grass Trees are susceptible to Pytophthora root rot and do not like being transplanted so slit cuts into the pot's bottom and sides and then bury the pot when planting out to ensure minimal root disturbance.
