Remember, fertilize this lightly and avoid overdoing it. You don’t want to end up burning the roots of your Dianella Clarity Blue.
Common Diseases
This plant is relatively resistant to pests and diseases. However, it is still important to keep an eye out for insects like aphids, mealybugs, and whiteflies. These insects can infest the plant and suck out its nutrients. If you notice any of these pests on your plant, it is important to act quickly and remove them before they have a chance to do too much damage.
Aside from pests, root rot is also a common problem with Dianellas. Since they like well-drained soils, make sure that the pot you’re using has good drainage. If not, the roots will start to rot causing the demise of the plant.
Prevention is always better than cure so make sure that you’re using the right pot, soil, and watering frequency to avoid this problem altogether.

If you choose to propagate by seed, it is best to sow the seeds thinly. Make sure to plant the seeds in well-drained soil and keep them moist until they germinate. Once they have germinated, you can transplant them into individual pots.
To propagate by division, divide the clumps in spring or autumn. Replant the divisions in well-drained soil and water them regularly until they have established themselves.
