Black Mondo Grass

Come coltivare l'erba nera del mondo ...

Space the plants about 4 inches apart, planting them in moist, well-drained soil, and immediately top-dress them with a layer of compost to help retain soil moisture. No seasonal feeding is needed. Each spring, remove the old foliage from around the plants. Where you want to thin the plants or propagate them, lift and divide the roots in spring. There are few pest and disease problems, but you may need to protect them against slugs and snails.

Light

Black mondo grass tolerates a wide range of sun conditions, but the warmer the climate, the most that shade is of benefit.

Soil

This plant prefers a moist but well-drained soil that has ample organic material. The ideal pH is somewhat acidic.

Water

Mondo grass needs to be kept consistently moist but not soggy. The hotter the temperature, the more water is required.

Temperature and Humidity

Ideal growing conditions are warm but not hot. This plant tolerates a wide range of humidity levels, provided the soil can be kept moist. Moist climates may see slugs and snails as a problem.

Fertilizer

Black mondo grass does not require much in the way of feeding. A single top-dressing of compost in the spring will suffice.

Propagating Black Mondo Grass

Black mondo grass is usually propagated by lifting and dividing the fibrous roots in spring.

1. Use a garden fork to pry clumps up from the ground.

2. Use your hands to tease apart groups of roots, dividing them into sections each containing a few leaves. A knife or sharp trowel may be necessary if the roots are thickly entwined.

3. Cut away any dried or diseased portions of roots.

4. Replant the clumps about 4 inches apart in the garden. If you cannot plant them right away, make sure to keep them moist until planting.
