How to Grow Lomandra
Lomandra longifolia
Lomandra is a tough, drought-tolerant Australian native grass with strap-like leaves forming a dense clump. Plant in any well-drained soil from full sun to heavy shade. Needs almost no care once established. Cut back hard every few years to rejuvenate. Excellent for mass planting, borders, erosion control, and low-maintenance gardens.
Yearly Lifecycle
Care Essentials
Once in spring with a slow-release native plant fertiliser. Lomandra is a light feeder and does not need heavy fertilising.
Watch For
- Root rot in waterlogged soil
- Occasional leaf tip browning in extreme drought
Care Requirements
Light
Full sun to heavy shade
Extremely adaptable. Grows in any light condition from full sun to dense shade, though flowering is best in sun.
Watering
Almost none once established
Extremely drought-tolerant once established. Water regularly only during the first growing season. Tolerates poor drainage better than most grasses but dislikes waterlogging.
Fertilizing
Light native fertiliser in spring
A single application of slow-release native plant fertiliser in spring is sufficient. Lomandra is a light feeder and thrives on neglect.
Pruning
Hard cutback every 2-3 years
Cut the entire clump to 15-20 cm in late winter every 2-3 years to rejuvenate. Remove brown or damaged leaves any time.
