This evergreen perennial ornamental grass tolerates short periods of freezing weather but may not last in temperatures below 20° degrees Fahrenheit (-7° C).
Dwarf mat rush is recommended for USDA hardiness zones 7 to 10.
It’s commonly grown in Alabama, South Carolina, and Georgia.
Further north, the cool summers and wet winters may harm the plant.
Grow it in containers in regions frequently dropping below freezing during the winter.
Watering and Feeding
Established breeze lomandra rarely need additional watering.
Potted plants and young plants need average watering, especially when placed in full sun.
Keep the soil moist until the plant matures.
NOTE: Optimal moisture and sunlight help produce fuller growth.
Adding a liquid fertilizer once per month during the spring and summer may encourage thicker, brighter blooms.
The plant is versatile once established and can survive long periods of drought or flooding.
Soil and Transplanting
Lomandra breeze grass grows in a wide range of soils, including light, sandy, and heavy, clay soil. It doesn’t have any special pH requirements.
Transplanting isn’t necessary, except for rearranging the garden or moving to a different container.
Transplant plants in the spring using moistened soil.
Grooming and Maintenance
- Trim back damaged leaves in the spring.
- The leaves may become damaged due to frost during the winter or severe wind.
- Prune dead foliage in early spring.
- Cut the blades back to about 6″ inches from the ground.
- The leaves will regrow throughout the spring.
- Annual trimming also increases the attractiveness of the clumps, making it easier to maintain the perfect shape and size.
- After trimming the plant, apply liquid fertilizer to encourage new growth.
- Along with trimming damaged leaves and annual trimming, the plant should be trimmed to half its size every three to five years to prolong its life.
- This increases the health of the leaves and keeps the size of the clump manageable.
How to Propagate Lomandra Breeze
Propagate lomandra breeze grass by clump division or seed.
Dividing the plant allows for continuous renewal, making it easier to cover a larger portion of a garden or landscape.
- Divide the plant in the spring.
- Carefully dig the soil around the plant and remove it from the ground or container.
- Loosen the soil to get a better look at the root ball.
- Separate the clump into two sections.
- Plant the sections in moist soil, either indoors or outdoors.
- When planting a mass of lomandra breeze plants, space them at least 2′ feet apart.
To propagate by seed, wait for the fruits to mature and turn brown.
When the fruit ripens, clip it from the plant and store it in brown paper bags.
Allow the fruit to completely dry before tearing it open.
Separate the seeds from the debris.
Sow the seeds in moist soil.
When sowing outdoors, protect the seedlings from strong winds with a plastic cover or grow in a greenhouse.
Keep the soil moistened.
About six weeks after sowing the seeds, the seedlings should be large enough for transplanting to their permanent homes.
As with the divided plants, space the transplants at least 2′ feet apart.
Lomandra Breeze Pest or Diseases
Lomandra breeze isn’t considered toxic or invasive.
It’s a relatively easy plant to grow with just a few pest concerns.
Pests are not a problem for outdoor growth but may appear indoors.
Aphids, mealybugs, and fungus gnats occasionally infest potted plants.
Aphids appear in clusters under the leaves, while mealybugs may appear all over the plant. Gnats tend to fly around the soil.
Take the infested plant outdoors and spray it with water from a garden hose.
Allow the plant to dry in the afternoon sun before bringing it back inside.
Repeat this process every other day for a week.
If the pests remain, treat them with a pesticide such as neem oil.
Suggested Lomandra Breeze Uses
