About Japanese lawngrass
Zoysia japonica, commonly known as Zoysia, is a warm-season grass prized for its dense texture and high tolerance to foot traffic and drought. It forms a lush, medium-green lawn, ideal for residential gardens, golf courses, and recreational areas where a durable and low-maintenance surface is desired. Its slow, lateral growth allows it to form a uniform and resilient turf.
Native range
East Asia, including Japan, China, and Korea
Care tips
It requires full sun for optimal growth, at least 6-8 hours daily. Once established, Zoysia is highly drought-tolerant but benefits from deep, infrequent watering to encourage a strong root system, especially during prolonged dry periods. It prefers well-drained soils, with a pH between 6.0 and 7.0. A common mistake is overwatering, which can lead to fungal issues and shallow root growth.
