The Disadvantages of the Amazoy Zoysiagrass

Amazoy zoysiagrass, also known as Meyer zoysia and Z-52, is an improved selection of Zoysia japonica. Amazoy zoysia produces a dark-green grass with a medium texture that spreads via rhizomes, or underground stems. Amazoy was introduced in 1951 as a “miracle grass” and has become the standard for all zoysiagrasses. Amazoy zoysiagrass is drought tolerant and makes an ideal lawn turf, yet the disadvantages of amazoy zoysiagrass sometimes outweigh the benefits.

Difficult to Establish

Amazoy zoysiagrass typically propagates through plugs, small cores of sod, or sprigs, sections of rhizome. Sprigging and plugging are labor-intensive methods of establishment. Amazoy sprigs typically do not have enough vegetative nodes to be viable. Plugging requires the use of a long-handled bulb planter to remove cores of soil the same size as the zoysiagrass plugs. Plugs require planting 2 to 3 inches below ground level to avoid mounding and require spacing of 6 to 12 inches to ensure coverage. Plugs need water four to six times a day until the roots establish, and it may take up to two years to fill in an area with bare soil.

Limited Adaptability

Amazoy zoysiagrass is more cold tolerant than other zoysiagrasses, but it does not adapt to the ice and snow cover of northern climates. It does not do well in the alkaline soils of southwestern climates either. Amazoy zoysiagrass grows best in southeastern climates where soil, temperature and water conditions favor growth. To survive, the grass goes dormant when temperatures dip below 40 degrees Fahrenheit, and it remains dormant until temperatures stay above 75 degrees Fahrenheit. Zoysiagrass’ limited adaptability makes it difficult to find in some markets, so mail order may be the only option.

High Maintenance

Amazoy zoysiagrass requires mowing every 10 to14 days during the growing season and may require weekly mowing during hot and moist weather when the grass tends to grow more rapidly. Amazoy zoysiagrass looks best when mowed with a reel mower. Reel mowers are more difficult to push than rotary mowers and may be harder to find in stores. A rotary mower effectively cuts Amazoy zoysiagrass, but the mower blade requires regular sharpening. Amazoy zoysiagrasses develops heavy thatch and mowing above a 2-inch height encourages a more rapid accumulation. When this occurs, the lawn requires renovation with a power rake.
