Dwarf mondo grass is a low-maintenance plant that does not require much care once established.

However, there are some things you can do to keep it healthy and beautiful.

Here are some tips for caring for dwarf mondo grass.

Watering Dwarf Mondo Grass

Dwarf mondo grass needs regular watering during the first year to help it develop a strong root system.

After that, you can water it only when the soil feels dry or during dry periods.

You can check the soil moisture by inserting your finger into the soil up to the second knuckle.

If it feels dry, water it thoroughly until it drains out of the bottom of the pot or the ground.

Fertilizing Dwarf Mondo Grass

Dwarf mondo grass needs a light feeding once a year in spring with a balanced, slow-release fertilizer.

You can use a granular or liquid fertilizer with equal amounts of nitrogen, phosphorus, and potassium (10-10-10).

Follow the label instructions for the amount and frequency of application. Do not overfertilize, which may cause excessive growth and reduce its cold tolerance.

Pruning Dwarf Mondo Grass

Dwarf mondo grass benefits from a light pruning in late winter or early spring to remove dead or damaged leaves and refresh their appearance.

You can use a lawn mower, shears, or scissors to cut it to about 2 inches (5 cm) high. This will encourage new growth and make it look neater.

Mulching Dwarf Mondo Grass

Dwarf mondo grass can benefit from a layer of organic mulch around its base to help retain moisture and prevent weeds.

You can use any organic matter, such as compost, bark, or pine needles.

Apply a 2 to 3-inch (5-7.5 cm) layer of mulch around the plant, leaving some space around the stem.

Do not pile up the mulch too high or too close to the stem, as this may cause rotting or fungal diseases. 

Possible Problems With Dwarf Mondo Grass

Dwarf mondo grass is generally pest and disease free, but it may occasionally suffer from some problems.

Slugs and Snails

These mollusks may feed on the leaves and stems of dwarf mondo grass, leaving holes and slime trails.

You can control them by using baits, traps, barriers, or natural predators such as birds or frogs.

Scale Insects

These tiny insects may attach themselves to the stems or leaves of dwarf mondo grass and suck out their sap, causing yellowing or wilting.

You can control them by pruning off the infested parts or spraying with insecticidal soap or neem oil.

Root Rot

This fungal disease may occur if the soil is too wet or poorly drained, causing the roots to decay and the plant to wilt or die.

You can prevent it by improving soil drainage and avoiding overwatering.

This fungal disease may cause brown or black spots on the leaves of dwarf mondo grass, especially in humid or wet conditions.

You can prevent it by providing good air circulation and removing any infected leaves.
