A Complete Guide to Planting and Growing Liriope and Mondo Grass

Planting and caring for Liriope and Mondo Grass is relatively straightforward, making these plants ideal choices for both novice and experienced landscapers. Here’s a comprehensive guide to help you successfully plant and grow these beautiful varieties.

General Planting Guidelines

1. Choose the Right Location

  • Light: Liriope thrives in partial shade to full sun. Mondo Grass prefers shade to partial shade.
  • Soil: Both types tolerate a range of soil types but prefer slightly acidic to neutral pH.

2. Preparation

  • Site Preparation: Remove any weeds, grass, or debris from the planting area. Loosen the soil to a depth of at least 12 inches.
  • Soil Amendments: If your soil is heavy clay or very sandy, consider adding organic matter, such as compost, to improve drainage and nutrient content.

3. Planting Time

  • Best Seasons: Spring and early fall are ideal for planting, allowing the plants to establish roots before extreme temperatures.

Planting Instructions

Liriope Muscari and Liriope Spicata Varieties

1. Liriope Muscari

  • Spacing: Space plants 10-20cm apart to allow for their spread.
  • Depth: Dig a hole that is slightly larger than the root ball. Place the plant in the hole, ensuring the crown is level with the soil surface.
  • Watering: Water thoroughly after planting and keep the soil consistently moist for the first few weeks.

Specific Varieties

  • "Big Blue": Considered taller, perfect for borders.
  • "Blue Skies": Good for colorful shade areas.
  • "Evergreen Giant": Best for larger areas needing a lush backdrop.
  • "Gold Band": Ensure it has partial shade to enhance leaf coloration.
  • "Munroe White": Plant in slightly sunnier spots for optimal blooming.
  • "Peedee Ingot": Great in containers; space appropriately.
  • "Royal Purple": Position to enjoy filtered sunlight for vibrant color.
  • "Samantha": Use in mixed beds for year-round interest.
  • "Silver Ribbon": Best combined with darker foliage plants for contrast.

2. Liriope Spicata

  • Spacing: Can be planted closer together (5-15cm) for a denser ground cover.
  • Depth: Same as Liriope Muscari.
  • Watering: Water well and monitor for moisture, especially during dry spells.

Mondo Grass Varieties

1. Ophiopogon Japonicus and Ophiopogon Intermediates

  • Spacing: Space plants 5-10cm apart for coverage.
  • Depth: Similar to Liriope, ensuring the crown is level with the soil.
  • Watering: Water thoroughly, keeping the soil moist but not soggy.

Specific Varieties

  • "Kyoto Super Dwarf": Use in rock gardens or as a low border.
  • "Nana Dwarf": Ideal for tight spaces, ensure it’s not overcrowded.
  • "Silver Mist": Works well in shadier spots to highlight its silver tips.
  • "Black Mondo": Best in contrast with lighter plants; ensure it's shaded.
  • "Black Dragon": Position in well-draining soil for best color retention.

Care and Maintenance

1. Watering

  • Establishment: Water newly planted Liriope and Mondo Grass regularly until established (about 6-8 weeks).
  • After Establishment: These plants are relatively drought-tolerant. Water during prolonged dry spells.

2. Fertilizing

  • Use a balanced, slow-release fertilizer in early spring. Avoid over-fertilizing as this can lead to excessive foliage growth at the expense of flowers.

3. Pruning and Maintenance

  • Cutting Back: In early spring, cut back any dead foliage to promote new growth. For Liriope, this can be done before new growth appears.
  • Weed Control: Regularly check for weeds and remove them to prevent competition for nutrients.

4. Pest and Disease Management

  • Liriope and Mondo Grass are generally resistant to pests. Monitor for any signs of disease or insect infestations, and treat accordingly with organic pesticides if necessary.

5. Dividing Plants

  • Every 3-4 years, divide mature clumps to maintain vigor and encourage healthy growth. Early spring is the best time for this process.

Liriope and Mondo Grass varieties are excellent choices for diverse landscaping needs. By following the guidelines outlined above, you can successfully plant, grow, and maintain these resilient and visually appealing plants. With their hardiness and low maintenance requirements, they will thrive and enhance the beauty of any garden or landscape design. Happy gardening!
