Light. Grows in full sun to full shade. Like other mondo grass, it does best with some shade.
Water. Like other mondo grass, it prefers soil that stays moist but drains well.
Soil and feeding. Mondo grass grows in sandy, loamy or clay soil.
Size. Grows to about 6 in, with very short, arching, blade-like leaves. Regular mondo grass reaches 6–12 in. It spreads slowly by runners.
Pruning. Little care is needed once established. Trim or mow it back in late winter or early spring if the foliage looks tired.
Problems to watch. Mondo grass is mostly pest free. Slugs can chew the leaves; use Snail and Slug Bait following the label.
Good to know. Mondo grass is highly salt tolerant and takes some foot traffic, which suits it to edging walkways.
