Planting Mondo Grass

When to Plant

Spring or early fall are ideal times to plant mondo grass.

How to Plant

1. Choose a suitable location based on light conditions.
2. Prepare the soil by removing weeds and incorporating organic matter.
3. Dig holes slightly larger than the root balls, spacing plants 4-6 inches apart.
4. Place plants at the same depth they were in their containers.
5. Backfill with soil and water thoroughly.
6. Apply a 2-inch layer of mulch around the plants, keeping it away from the stems.

Caring for Mondo Grass

Watering

• Water regularly during the first growing season to establish a strong root system.
• Once established, mondo grass is relatively drought-tolerant but benefits from occasional deep watering during dry spells.

Fertilizing

• Apply a balanced, slow-release fertilizer in early spring.
• Avoid over-fertilizing, as this can lead to excessive growth and reduced hardiness.

Pruning and Maintenance

• Mondo grass requires minimal pruning.
• In late winter or early spring, cut back any damaged or discolored foliage.
• Divide clumps every 3-4 years to maintain vigor and control spread.

Winter Care

In colder regions, apply a layer of mulch around the base of the plants for extra protection during winter.

Common Pests and Diseases

Mondo grass is generally resistant to pests and diseases, but watch out for:

• Scale insects
• Slugs and snails
• Crown rot (in poorly draining soils)

Address any issues promptly with appropriate organic or chemical controls.
