Zoysia Grass
A Fine Leaf Zoysia Lawn

Couch or Zoysia

For anyone considering purchasing a new lawn for their home, Couch is often one of the first grass types to be considered. And why not… Couch has a long and trusted history as a home lawn, it has a nice fine leaf, is easily maintained, looks great when looked after correctly, and can be easily treated for most weeds, pests and disease.

However, from one perspective, homeowners who are thinking about a new Couch lawn, can also consider another lawn variety which looks not too dissimilar to Couch, with a similar fine leaf, and is a little easier care as well. And the grass referred to here is called Zoysia.


Benefits Of Couch

Let’s start with the advantages of owning a Couch lawn. Couch really is a very good all round grass type, it’s cheap to buy, it handles wear and tear very well, repairs itself from damage fast, is quick to grow, has a pleasant fine leaf, and when maintained properly can be a rather easy lawn to get right when it comes to creating a lawn with either an acceptable or even brilliant appearance - depending on how much work we’re prepared to put into the lawn. Couch is also highly tolerant of almost all pesticides and herbicides, and is very drought tolerant.


Disadvantages Of Couch

Every lawn type has disadvantages, including both Couch and Zoysia. But for the purpose here of considering a Zoysia lawn over Couch, let’s have a look at Couch.

Couch is very intolerant of any shade, it requires the most amount of direct sunlight of all the grass types - along with Kikuyu, and will simply no longer flourish or even grow at all sometimes when surrounding trees begin to grow, or other structures or gardens are creating excessive shade levels.

Couch is a very vigorous growing grass, which means it requires frequent lawn mowing, de-thatching (vertimowing) every so often, and can also invade garden beds and paths, and if left for too long without mowing, can become long and straggly.

Couch is also susceptible to all lawn diseases, lawn pests and weeds, and requires ongoing regular lawn fertilising in order to maintain a lush dark green appearance.

The purpose here is not to put Couch down, just in being honest in saying that this well loved grass is just a normal grass like most others, in that it has negatives as well as positives. And for the purpose of this article, we’ve listed these things, so we can then compare the difference with a Zoysia lawn for these same traits.

Considering A Zoysia Lawn

The purpose of this article is simply to compare two fine leaf lawns with each other. With the strong and long history of Couch, we simply believe that Zoysia - as another finer leaf lawn could be considered as a worthwhile alternative to Couch, which may also be stronger in some areas where Couch is susceptible. However, all lawns do have positives and negatives, and this goes for Zoysia also.

Zoysia grass lawns such as Compadre, Nara, Empress, Empire and others all have all of the advantages of Couch, including having a finer leaf blade - though not as fine as Couch, excellent tolerance for chemical sprays such as herbicides and pesticides, can tolerate heat stress and drought, and have good wear and tear properties.

But apart from all of these same advantages that Couch has, Zoysia has a few more. Zoysia can tolerate shade much better than Couch (although not as good as Buffalo), it has a low invasive nature so it won't invade garden beds as vigorously, it grows slower than Couch and so requires less mowing, and requires almost no de-thatching at all, and is reported to be naturally resistant to invasions of lawn grubs such as Sod Webworm and Armyworm.

And like Couch, Zoysia is also a lovely soft lawn.


Other Considerations

Whereas Couch is tough, and can repair itself quickly from damage, Zoysia is a little different in its strengths and weaknesses. Zoysia can withstand wear and tear for longer - based on the high silica content in its plant structure, but it may not repair itself from damage as quickly as Couch can - once it does get damaged, just because it naturally grows a little slower than Couch.

While some homeowners may consider the slightly higher outlay to purchase Zoysia over Couch, this may be small in comparison to savings to be made over the life of the Zoysia lawn. Savings in money in mowing costs, pesticides, de-thatching and fertiliser.

So if you are considering a new fine leaf grass, such as a Couch lawn, then why not also give some thought and have a look at Zoysia as well.

Lawn Care Facts
Lawn Fact:
Frequent shallow watering promotes a shallow root system that struggles for life under heat stress. A lawn constantly under stress will send out masses of seed heads, be weak and easily damaged, be slow to repair, and be far more susceptible to diseases and weeds.
