With proper care, dwarf mondo grass forms a lush, soft, green carpet that thrives in shade and resists foot traffic. Follow these tips to successfully grow this ornamental grass in your yard.
Selecting a Site
Dwarf mondo grass requires moist, well-drained soil and partial to full shade exposure. When selecting a site, consider the following:
- Soil – Mondo grass thrives in loamy, acidic soil rich in organic matter. Improve drainage in clay soils before planting.
- Sun – Dwarf mondo needs shade for at least half the day, especially in hot climates. Dappled sunlight or morning sun is ideal.
- Moisture – Ensure the site does not completely dry out. Plan to irrigate if rainfall is insufficient.
- Drainage – Avoid areas where water collects after rains. Good drainage is essential.
Preparing the Soil
Proper soil preparation helps dwarf mondo grass establish quickly:
- Loosen the soil to a depth of 8-12 inches using a rototiller or garden fork. Break up large clumps.
- Mix in 2-3 inches of compost or well-rotted manure to enrich the soil.
- Test the pH and amend if needed. Target a pH of 5.5-6.5.
- Rake the area smooth and remove any debris, rocks or weeds.
Planting Dwarf Mondo Grass
Dwarf mondo grass is sold as young plants, plugs or sod. Follow these tips for planting:
- Spacing – Space plugs or plants 6-12 inches apart depending on desired density.
- Depth – Plant mondo grass at the same depth it was growing in the container.
- Division – Divide mature clumps in early spring or fall. Replant 8-12 inch pieces.
- Watering – Water thoroughly after planting. Keep soil moist until established.
Caring for Dwarf Mondo Grass
A few easy care practices will keep dwarf mondo grass looking its best:
- Watering – Water 1-2 inches per week. Avoid overwatering.
- Fertilizing – Apply a balanced fertilizer in spring and fall. Use a slow-release product.
- Weeding – Hand pull weeds to prevent competition, especially when young.
- Edging – Install a border to contain the grass and neaten the edges.
- Pruning – Remove any damaged, diseased or unsightly foliage.
Propagating Dwarf Mondo Grass
Once established, dwarf mondo grass can be propagated by division in spring or fall:
- Use a sharp spade to carefully divide large clumps into smaller sections.
- Each division should have several shoots and a good portion of the root mass.
- Replant divisions immediately at the same depth, watering well.
- Divisions quickly develop into new plants, filling back in within one season.

Frequently Asked Questions
How fast does dwarf mondo grass grow?

Is dwarf mondo grass deer resistant?
Yes, dwarf mondo grass is seldom damaged by deer and other wildlife that feed on lawn grasses. Its tough foliage and unpalatable taste make it a good low-maintenance option for yards with deer or rabbits.
Does dwarf mondo grass spread aggressively?
This dwarf mondo variety has a slower, more compact growth habit compared to the species. It gently spreads via underground stems but is not considered aggressive or invasive. Proper spacing at planting helps keep it contained.
What time of year is best for planting dwarf mondo grass?
Early spring or fall is ideal for planting dwarf mondo grass plugs or divisions. This avoids summer heat stress and allows the plants to establish roots before cold weather arrives. However, container-grown plants can be planted successfully throughout the growing season with proper care.
How do I winterize my dwarf mondo grass?
No special winterizing steps are needed in most cases. Simply continue watering until hard freezes begin. The dense evergreen foliage remains attractive through winter then regrows vigorously in spring. Apply a winter mulch in very cold climates for added protection.
