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. If required use slow release fertiliser in spring. Every 1-2 years cut back 15cm above the ground (will look better with pruning every year, this depends on your requirements). As this is a fast growing Dianella, it will require cutting back more often, but responds very well to being cut back. If it is not cut back every 2 years (minimum), it can become overgrown, and be short lived. With regular pruning it is a reliable, long lived, tidy Dianella.
