Be attentive if you are planning to place a new lawn!

Are you confused about which grass to choose for your lawn from St. Augustine grass and Zoysia grass?

The reply is, “Both are perfect to express your lawn beautifully” but there are some similarities and dissimilarities too that should be looked at while selecting.

In this post, we will explain the dissimilarities between them and the best types of both styles of grass to help you make an exact decision for your dream lawn.

St. Augustine vs. Zoysia:

Before laying/seeding any of these grasses in your lawn, you must look for the factors like natural light & heat requirement, cost of maintenance, acceptance against drought and lawn diseases, and color retention.

Through the below-mentioned table of comparison between these two kinds of grass, you will be able to recognize and understand the differences more easily:-

St. Augustine GrassZoysia Grass
Deep green color.Bright green color.
The texture is non-easy and rough.The texture is easy and plain.
Minimum upkeep is required.Regular upkeep is required.
Costs much less in the establishment.Costs greater in the establishment.
Comes back quickly in its original color after fall, usually in the early spring period.Comes back slowly in its original color after fall, usually in the later spring period.
Relies on the stolons only.Relies on the rhizomes and stolons both.
The length of one grass blade is nearly 9mm.The length of one grass blade is nearly 7mm.
Nitrogen content is higher.Nitrogen content is lower.
Soil pH levels should be ranging from 5 to 8.5.Soil pH levels should be ranging from 5.8 to 7.

To make the concept clearer, here are types of both the grasses:

St. Augustine:

St. Augustine is a popular turfgrass because it has a very deep root system, is drought-resistant, and tolerates shade well. However, St. Augustine does have several limitations that must be considered by both residential and commercial lawn owners as they plan their grass planting or renovation project.

There are three types of St. Augustine grass.

  1. Seville.
  2. Palmetto.
  3. Floratam.

The best among the above types of St. Augustine is Floratam. It is capable of fighting against tough grass viruses and diseases.

Its long and thick blades are resistant to insects and bugs. It keeps its color throughout the year, and if it has been affected by the snow or hard summer, it swiftly comes back to its original shade.


St. Augustine has some significant disadvantages as a lawn grass, including that it can be very difficult to establish, overseed or repair. St. Augustine also has a relatively high water requirement and is susceptible to pests, diseases, and heat stress. St. Augustine grass (Stenotaphrum secundatum) is not the best choice for lawns in several locations. The most common reason is that St. Augustine does not tolerate heat well, especially during the summer months. In addition, St. Augustine cannot tolerate wet soils and may be difficult to establish in heavy clay soils simply because these soils do not drain well enough for this species.


Zoysia grass is lawn grass that requires less water and fertilizer than other types of grass. It spreads by below-ground stems and forms a thick, deep root system. Zoysiagrass can adapt to many soil conditions.

Zoysia grass has an extensive fibrous root system which makes it very tolerant of drought, heat, and even some shade. It can be difficult to grow in the Deep South, where it stays green year-round because that climate is too moist for zoysia grass. In these regions, homeowners should consider centipedegrass or bermudagrass instead.

Zoysiagrass (Zoysia spp.) is a good choice for lawns with the following advantages:

  • It tolerates heat and drought well, making it appropriate for most hot climates.
  • Zoysiagrass is an excellent shade grass and tolerates both sun and shade in most situations.
  • It tolerates wet soils but also has good drought tolerance.
  • It is easy to establish and oversee.
  • It is rarely seriously damaged by pests, disease, or poor mowing practices.
  • It is very tolerant of cool soils and chills easily in winter.


It is difficult to establish in areas where lawns are already well established because of the lack of seed germination and poor seedling vigor. If you over-seed Zoysiagrass at a rate greater than 10 lbs. per 1,000 square feet, you will likely experience thatch problems due to increased thatch depth and increased thatch abundance because the grass produces a higher percentage of rhizomes as compared to tillers (aerial shoots).
