An introduction to the characteristics, habits and daily care methods of Chrysopogon aciculatus

Chrysopogon aciculatus is a perennial herb in the grass family, named for the slightly swollen internodes of its creeping stems, which resemble bamboo joints. It is fairly widely distributed in the warm, humid regions of southern China. It is often used as a lawn grass for courtyard green spaces and slopes, and can also serve as a ground cover to clothe bare ground, making it a relatively common native grass species in landscaping.

In terms of characteristics, the creeping stems of Chrysopogon aciculatus spread along the ground, and the nodes readily take root and sprout, so it forms a lawn quickly and has strong covering power; its stems and leaves are low and dense, so it needs less frequent mowing. It likes warmth and sunlight, tolerates heat and drought, and is also fairly tolerant of poor soil and moderate foot traffic. It is not demanding about soil, is suited to extensive management, and has low maintenance costs.

For care, Chrysopogon aciculatus is mostly propagated by laying cut sections of creeping stem or by division. After laying, press the soil firm and water promptly, keeping it moist until it takes root and greens up. Once the lawn has formed, routine management mainly consists of watering, light fertilizing and moderate mowing. Pay attention to replenishing water in dry seasons, and drain promptly in the rainy season to avoid root rot caused by prolonged waterlogging.

In application, Chrysopogon aciculatus is suitable for courtyard lawns, soil stabilization on slopes and the construction of public green spaces. In its young, tender stage, the stems and leaves can also be used as forage. Note that after it sets seed, the seeds bear awns and readily stick to people's clothing and to animal hair; in ornamental or activity areas, it can be mowed appropriately to reduce seed-head formation. At low winter temperatures the leaves may turn yellow and go dormant, and they gradually return to green after temperatures rise in spring.
