Water as required for 8-13 weeks until established. Plant in a well mulched garden (chunky mulch is recommended).
Ensure crown or base of plant is not below soil or mulch level. Use slow release fertiliser in spring (especially for nutrient poor soils).
Remove older foliage as required or every 2-3 years cut back close to the ground (will look better with pruning every 2 years, this depends on your requirements).
