How to Care for Lomandra Grass
Lomandra grass is an evergreen plant with minimal care requirements. If you want to bring this hardy perennial to your place, you need to know the following basic care tips.
a) Sunlight Requirements
Lomandra grass can grow well in almost all light conditions, including full sun and partial sun. If your garden receives full sun, you can plant your mat rushes there without any worries. Otherwise, it will also do just fine in part shade.
b) Soil Requirements
Mat rushes can do well in all types of soils, including neutral, sandy, loamy, clay loam, sandy loam, and poor soil. Since these variants of grass spread widely, they also help prevent erosion.
c) Water Requirements
Lomandra grass is versatile, making this plant perfect for different landscapes. Most variants of this plant have moderate water requirements. They can tolerate very wet to dry conditions. Since these plants are hardy, they can even survive drought and occasional flooding. However, remember that the young plants need more water than the fully grown ones. Also, make sure to use filtered water at room temperature for watering.
d) Temperature Requirements
If we talk about the temperature requirements, most varieties of Lomandra can easily tolerate a vast range of temperatures. However, remember that -6ºC or 20ºF is the bottom line.
e) Humidity Requirements
Though lomandra grass is highly tolerant to drought, they need moisture for growth. Well suited to coastal conditions, these plants need good air circulation to thrive.
f) Fertilizer Requirements
If we talk about fertilizer needs, you need to fertilize young plants twice a month throughout spring, summer, and autumn to encourage growth. Once fully grown, minimize fertilization. Add a layer of compost and organic pelletized fertilizer in spring.
g) USDA Zones Requirements
This evergreen perennial herb can grow well outdoors in USDA zones 8 to 11. If you belong to a hardiness zone below 8, we don’t recommend planting it directly in open ground but rather grow it indoors.
Lomandra Grass Flowering
The flowering time of most variants of lomandra grass is from spring to summer. They produce spikes of small cream & yellow blooms clustered along stems. Since the flower stems are usually smaller than the leaves, the flowers are often hidden within the dense foliage. Also, most lomandra blooms are deliciously scented. However, be careful while getting a whiff, as they are spiky.
Lomandra Grass Appearance and Size
Lomandra Grass can grow 4 to 5 feet tall and can have a spread of 6 feet in width. Lomandra is a flexible plant with finely textured long leaves, giving the appearance of grass from a distance. The narrow-leaved, evergreen foliage of these perennials is complemented by small, scented mustard flowers, making them a striking addition to gardens and indoors. The leaves of lomandra plants can grow up to 1 meter long and up to 12 mm wide.
Pruning Lomandra Grass
Lomandra plants have become popular landscape plants due to their grass-like appearance and almost no maintenance needs. Though these perennials don’t need regular pruning like grasses, they can benefit when trimmed to the base into ball shapes. Trimming can help you maintain the beauty and health of these grass-like plants. Here’s how to prune your lomandra grass:
- When this grass-like plant begins to appear messy, damaged, or unattractive, it means it needs pruning.
- Use sharp head shears for cutting. Make sure to clean the tool with rubbing alcohol.
- Get right down to the base of the plant and give it a chop-off a few centimeters above the ground.
Additionally, spring, summer, and early autumn are the right seasons to prune lomandra. However, whenever you see dead or brown leaves, make sure to take them off immediately to maintain the plant’s look.

Step 3: Trim the leaves to about third of the original length.
Step 4: Plant these clumps in the soil.
Step 5: Water them regularly for about a month to encourage root formation.
