Grass Tree (Xanthorrhoea Glanca)
Grass Trees from Australia are slow in growth.
Mature plants are centuries old. They have a life span of 600 years.
It is noted that it took 27 years to grow to a height of 30 cm. As it grows only 1-2 cm per year, a 1 metre grass tree is usually about 100 year old.
Conditions for planting a grass tree
An area open to the sun
Well drained soil
Plant deep enough so that the top of the root ball is at ground level
Water the plant twice a week. Making sure that the roots are thoroughly wet with around 50 litre of water per week.
Fertilize once every 3 months.
Apply pesticide only if needed.
