Planting
How many liriope plants per square meter?
Short answer: Liriope is usually planted 25 to 30 cm apart: about 11 plants per m² at 30 cm and about 16 per m² at 25 cm. Dwarf Mondo Grass, being smaller, is planted 10–15 cm apart, which means 44 to 100 plants per m².
Reference table
| Spacing | Plants per m² (approx.) | Recommended for |
|---|---|---|
| 10 cm | 100 | Dwarf Mondo Grass, instant coverage |
| 15 cm | 44 | Dwarf and regular Mondo Grass |
| 20 cm | 25 | Regular Mondo Grass, compact liriope |
| 25 cm | 16 | Liriope Super Blue, Aztec Grass |
| 30 cm | 11 | Liriope Ever Green, large areas |
Formula: plants per m² = (100 ÷ spacing in cm)². Add 5–10% extra for replacements.
More plants or fewer?
Denser planting covers the area faster and reduces weeds from the start, but costs more. Wider spacing is cheaper and the plants will still close the gap over time, because both liriope and Mondo Grass spread.
Planting tips
- Prepare the soil and make sure it drains well.
- Plant in a staggered (zigzag) pattern for even coverage.
- Water regularly during the first year so roots establish.
- Use mulch while the plants fill in.
Frequently asked questions
How long does liriope take to cover the ground?
It depends on planting density, climate and watering. The denser the planting, the faster it fills in. Regular watering in the first year speeds up establishment.
