Dazzling Lomandra Grass for NZ Gardens

Lisa Eclesworth

 

Lomandra grass is a tough New Zealand favourite in gardens as a no-fuss plant. It is a gorgeous texture, clump-forming grass that may be utilised in any landscape.

The Plant Company, NZ gardening experts you can trust, has some expert advice to ensure you grow these useful plants successfully. With very little effort, lomandra adds year-round beauty when planted in containers, borders, or on slopes.

Choosing the Right Variety

You will be happy with the results when you choose the correct variety. 

Some of the best New Zealand gardens include:

  • Longifolia: Fast-growing and perfect for large spaces, attaining up to 1.5m.
  • Little Con: Compact at 30-40 cm, this variety is ideal for borders or containers.
  • Lime Tuff: Vibrant lime-green foliage for a striking contrast.
  • White Sands’: Variegated leaves for added visual interest.

Planting Lomandra for Success

Getting the planting basics right ensures strong, healthy growth:

  • Location: It prefers full sun; however, it tolerates partial colour.
  • Soil: Well-draining soil enriched with compost or sheep pellets. Avoid heavy clay.
  • Spacing: Plant at a distance of 40-50cm for dense coverage or 70-90cm for a more open appearance.
  • Timing: Best planted from mid-autumn to the end of spring for strong roots.

A simple drainage test before planting can prevent trouble later—dig a hole, fill it with water, and test if it drains within 24 hours.

Watering and Feeding Tips

This grass is drought-tolerant once established but benefits from proper care:

    • Watering: Deep watering every third day in summer, less frequently in cooler months. Potted variety needs watering twice weekly in summer.
    • Fertiliser: Apply a balanced garden fertiliser in spring. For pots, use slow-release fertiliser tablets.
  • Organic Option: The Plant Company’s organic fertiliser works nicely for eco-aware gardeners.

Over-watering can cause root rot, so let the soil dry barely between waterings.

Pruning and Maintenance

Keeping your lomandra tidy is simple:

  • Light Trimming: Remove dead or yellowing leaves anytime.
  • Hard Pruning: Cut back to 5-10cm in spring to rejuvenate older plants.
  • Frost Care: Protect young plants with frost cloth in winter and trim damaged foliage after frosts pass.

Common Problems and Solutions

Even tough plants face occasional issues:

  • Yellow Leaves: Often resulting from over-watering or bad drainage. Improve soil conditions.
  • Leaf Spots: Cosmetic fungal issues during humid weather—ensure good airflow.
  • Pests: Rare, but mealybugs may appear. Treat with a gentle insecticide if needed.

Landscaping with Lomandra

This versatile grass shines in many settings:

    • Slopes and Banks: Excellent for erosion control with its deep roots.
    • Borders and Paths: Creates neat, structured edges.
  • Pots and Containers: Adds a cutting-edge touch to patios and courtyards.
  • Companion Plants: Pair with flaxes, Astelias, or decorative grasses for comparison.
