Planting Mondo Grass
When to Plant
Spring or early fall are ideal times to plant mondo grass.
How to Plant

Caring for Mondo Grass
Watering

- 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.
