Zoysia japonica: Irrigation guide

As the title says, today we talk about lawns and we leave aside the issue of orchards a bit. We go more to the landscaping and decorative branch of a garden, which we should never underestimate. What we bring you today, Zoysia japonica , will call your attention for the qualities it has, for those who live in hot and dry areas.


The genus Zoysia comes from the Asian continent , specifically from Japan and China. The curious name comes from the Austrian botanist who studied them (Karl von Zoys).

In Hawaii for example, it is one of the most widely used grasses given its characteristic resistance to unfavorable weather conditions, where it grows throughout the year. Although today we are talking about this specific species, you have to know that there are more species within the genus Zoysia , such as  Zoysia matrella, Zoysia tenuifolia, Zoysia matrella, etc. 


The particular thing that it has and the fact that it has gained the prominence of today in Gardenprue is due to overthrow all the approaches that the lawn consumes a lot of water . This is not the case of this species, since among its many qualities it has that of being resistant, having few irrigation needs (compared to other types of species) and being tolerant to saline irrigations.

It came to be considered (now we do not know) as a magical lawn , since it had many advantages (now we will tell you why not anymore) and it had very few disadvantages.

What problem would exist with a lawn that withstands drought, is resistant to blows and footfalls, withstands a great variety of temperatures, is quite homogeneous,  requires little fertilization and few phytosanitary treatments?

One and quite large, which has caused it to be relegated to other types of grass. Zoysia japonica has quite a few drawbacks in terms of producing seeds for replanting.

However, for those who do not have a problem with this problem, I doubt that they will find a variety that offers as many possibilities as this one. If not, you can always choose from other varieties of lawns.  Do you want to see some of its specifications?


Once we are decided to plant this grass we have to know the water needs, a very important factor. When we plant Zoysia japonica in our garden, the irrigation needs are moderate. It is logical, at the beginning it is weak and it is where it needs the highest amounts of nutrients to grow. The good thing about it is that once it takes root and begins to grow, the irrigation is proportionally inverse, until values ​​established in the hottest season (July-August) with irrigations spaced 10-15 days for non-hot climates, and 1 or 2 times a week for very hot climates, unthinkable for any other genre. In autumn, when the heat dissipates, the risks are further reduced, sometimes cutting them completely in case of periodic rain.


The best time to sow is at the end of spring (June) or throughout the summer (July, August and September). Normally the seeds are of medium size, and in 1 gram up to 3,500 seeds are obtained, which produce a fairly high and uniform density on the ground, with almost 35,000 plants per square meter.
