Amazoy zoysia grass, also known as Meyer or Z-52, is a cultivar stemming from Zoysia japonica. Amazoy was released in 1951 and is a warm-season grass. It is often referred to as a miracle grass, though the claims of how well it grows anywhere throughout the United States may be exaggerated, according to Ronald C. Smith, a horticulturalist from the University of North Dakota.
Appearance and Texture
Amazoy zoysia grass has a natural, deep-green color, giving a lush look to the lawn. Other types of grass often require extra nitrogen to achieve a deep-green color, but Amazoy only requires 1 1/2 to 2 1/2 lbs. of nitrogen per 1,000 square feet, in total, per year, to remain lush and healthy. The nitrogen is usually applied in half the total amount; once in the spring and once in the fall. The texture of Amazoy zoysia grass is better suited to lawns than the original Zoysia japonica. While the japonica variety is coarse, the Amazoy is a medium-textured grass.
The Amazoy zoysia grass is considered one of the most cold-tolerant grasses of the zoysia grass varieties. While not as shade-tolerant as the emerald variety of zoysia, its ability to withstand cold better than many warm-season grasses, coupled with zoysia grass' tolerance for various soil types, means Amazoy can be grown where other warm-season grasses may not thrive.
Growth Rate and Maintenance
Amazoy has a relatively fast growth rate, compared to other grass varieties. It produces few rhizomes during its growth, but once established it produces an excellent lawn. Unlike other grasses, both of the zoysia grass cultivars or other grass varieties, Amazoy needs less frequent mowing. The University of Florida Extension recommends mowing Amazoy zoysia grass once every 10 to 14 days. Mow the grass to a height of 1 to 2 inches, which can best be achieved by using a reel mower instead of the traditional rotary-blade mower.
