Emerald Grass Zoyzia japonica
Emerald Grass originates from Asia, more specifically, it originates from Japan.
Emerald Grass is very resistant to temperature variation and to the cold, as well as, it is very resistant to insect infestation and weed. Furthermore, it is the most appropriate for embankments and slopes. Therefore, Emerald Grass has been used a lot for residential and commercial gardens beautification and for recreational areas.
Emerald Grass presents narrow and small leaves with an intense green color. As its name indicates, it has a similar green color of an emerald gemstone.
The Emerald Grass tolerates well big variations in temperature, the sunshine and mild excess of water. Therefore, this grass has been widely used on lawns at countries and regions of temperate climates.
When properly cared for, the Emerald Grass lawns form a very dense carpet, which is also very nice to walk on barefoot.
Where to plant the Emerald Grass?
The Emerald Grass is a rhizomatous type of grass, that is, the stem is below the ground and outputs the leaves upward. Therefore, the Emerald grass is widely used and is perfect for:
- Residential gardens
- Closed neighborhoods
- Commercial gardens
- Ball parks, sports grounds
- Borders of swimming pools
- Recreation areas and playgrounds
- Embankments and slopes
When can I plant the Emerald Grass?
The Emerald Grass can be planted at any time of the year, since it is very resistant to the cold and heat.
How can I plant the Emerald Grass?
Before receiving the grass: Prepare the site where the grass will be planted removing all kinds of weeds, stones, dirt, and debris. Try to prepare the soil more uniformly as possible without unevenness and small bumps. No prior fertilization of the soil is necessary, however, depending on the region, the consultation of an expert in soils or an agricultural engineer is recommended to check and analyze the soil before planting.
The transportation of the grass: Normally, the Emerald Grass is transported as carpet tile rolls of 40 cm x 125 cm (16” x 49”). In this way, besides making it easier to plant, it also avoids damages to the grass that can be transported at long distances.
Receiving the grass: Once the grass is unloaded from the truck, it has to be planted immediately after and the grass carpet tiles should be placed side by side. The small pieces of grass can be used to fill in the gaps between the grass tiles. All the planted area should be covered with earth after planting is completed.
Once planted, the Emerald grass should be watered heavily and daily in the first 30 days after the completion of the planting.
Once the grass has been well settled and adapted to the ground: the Emerald grass can be watered time to time, preferentially using an automatic irrigation system to avoid excessive loss of water and optimize the homogeneous irrigation of the lawn.
Grass trimming: the Emerald grass can be trimmed when the grass reaches 2 to 3 cm (0.8” to 1.2”) of height.
Fertilization: the Emerald grass does not require constant fertilization. Furthermore, the fertilization of the lawn at Fall or Winter is not necessary since the grass tolerates well the intense cold and will keep dormant at these time of the year.

The Emerald grass can be planted under plain sunshine, at fertile soils, with biannual fertilization and regular watering, preferentially in the morning.
It is not indicated for places with intense circulation of people and cars and at shaded areas.
The Emerald grass grows by the division of enrooted rhizomes.
The Emerald grass must be trimmed always when it reaches 2 to 3 cm (0.8” to 1.2”), and should not be cut more than 1/3 of its height. We recommend the grass trimming during spring time. After the removal of the dead cut leaves, the grass will present a more vivid green color.
The ideal pH of the soil for Emerald grass should be around 6.0 to 6.5 (slightly acid).
Weeds and Emerald Grass
The Emerald grass is very resistant to weeds.
If at the time of planting there are some few weeds on the area, the tendency is for its disappearance with the growth of Emerald grass, since this grass forms a very dense carpet when compared to other grasses, which prevents the growth and multiplication of weeds.
However, if the area where the grass will be planted is infested with a lot of weeds, it is recommended to treat the area by removing all weeds possible before planting the grass.

- The Emerald Grass is very good to avoid erosions in embankments and slopes and is very good to prevent weeds to grow with time, since it forms a very dense grass carpet
- The Emerald Grass is resistant to moderate to low circulation of people and trampling. It is very resistant to diseases, fungi and insects, and tolerates well big variation in temperature, excess of water and sunshine. It does not require too much fertilization.
- The Emerald grass can adapt well to several types of soil, with pH acid, neutral or basic, although it prefer slightly acid soils of pH between 6.0 to 6.5.
- The Emerald Grass requires less fertilization when compared to other types of grasses. But it is also dependent on the region where the grass is planted. Therefore, a consultation to a soil specialist or an agronomist is always recommended.
- The Emerald Grass requires little irrigation.
- The Emerald Grass is resistant to diseases and weeds.
- The Emerald Grass presents an optimal cost-benefit ratio, with a low maintenance cost.
- The Emerald Grass does not tolerate the intense circulation of people and trampling.
- The Emerald Grass is not recommended for shaded areas, and when not cared properly, it can generate a lot of dead and dry leaves.
- Emerald Grass present a slow growth rate, therefore, when damaged, it can take a long time to recover itself.
The Emerald Grass is grown in grass nurseries and is normally sold as carpet tiles (pallets) or rolls of 40 cm x 125 cm (16” x 49”).
The Emerald Grass is the most sold grass in Brazil.
The Emerald Grass is actually a hybrid of two different species of Zoysia: the Zoysia japonica and the Zoysia tenuifolia.
The Emerald Grass is of Japanese origin, which explains its scientific name as Zoysia japonica. It is found at the sunny slopes all over Japan.
