St. Augustine grass features lush greenery and good heat tolerance but demands regular watering and is susceptible to diseases and pests. Zoysia grass offers durability, drought resistance, and low maintenance, but takes longer to establish and may turn brown in colder seasons.

Ultimately, the selection depends on the climate, desired maintenance, and specific lawn preferences.

Fear not, because this comprehensive guide will walk you through the differences between these popular grasses, their unique characteristics, and their maintenance requirements.

By the end, you’ll have a clear understanding of both grass types, and which grass is best suited for your lawn, considering factors like climate, soil type, and your personal preferences.

Short Summary

  • St. Augustine and Zoysia grass have distinct characteristics, such as color, texture, growth habits and propagation methods which should be considered when selecting the ideal lawn for your needs.
  • Climate considerations should be taken into account when choosing between St. Augustine or Zoysia grasses. Soil type compatibility is also important to consider for optimal results.
  • Budget and maintenance preferences must also be evaluated in order to determine the best option based on the cost of establishment & maintenance plus the amount of time one is willing to invest in lawn care.

Characteristics of St. Augustine and Zoysia Grass

When it comes to color and appearance, St. Augustine grass boasts a blue-green to a dark green color, while Zoysia grass varies from emerald-green to dark green.

Texture-wise, Zoysia grass offers a fine and smooth turf, whereas St. Augustine grass is coarser. Both grasses exhibit creeping growth habits, making them warm weather, low-growing turf options.

However, their propagation mechanisms differ; Zoysia grass spreads through both above-ground and subterranean shoots, while St. Augustine grass only propagates through above-ground shoots.

These characteristics impact the overall appearance and performance of your lawn. For example, a lawn with Zoysia grass might have a denser, more uniform look, while a St. Augustine lawn might appear more textured and lush.

Ultimately, the choice between these grass blades depends on your personal preferences and the specific conditions in your area.

Color and Appearance

While both St. Augustine and Zoysia grasses flaunt attractive shades of green, St. Augustine grass usually exhibits a blue-green hue. On the other hand, Zoysia grass ranges from an emerald-green to a dark green hue.

This difference in color might not be a deciding factor for everyone, but it’s essential to consider if you’re looking for a specific shade to complement your landscape design.

Turf Texture

In terms of turf texture, Zoysia grass has a fine and smooth feel, making it pleasant to walk on and perfect for yards with heavy foot traffic, which is why it’s considered a good turf grass. St. Augustine grass, however, has a coarser texture, which might not be as comfortable underfoot but can still create a visually appealing lawn.

This difference in texture is an essential factor to weigh when choosing the right grass for your lawn, depending on whether comfort or visual appeal is your priority.

Growth Patterns

Zoysia grass:

  • Is slower-growing
  • Turns green later than St. Augustine grass, which turns green in early spring
  • Its slow growth rate is advantageous because it allows Zoysia grass to become denser with each growing season.

A St. Augustine lawn, on the other hand, grows more rapidly, which might require more frequent mowing but results in quicker establishment and coverage.

The growth patterns of these grasses should be considered when deciding which grass best suits your lawn care schedule and preferences.

Maintenance Considerations for St. Augustine and Zoysia Grass

While both St. Augustine and Zoysia grasses are warm-season and creeping, their maintenance requirements vary, particularly when it comes to mowing, fertilization, and watering. St. Augustine grass requires less frequent mowing and has an ideal height of 3-4 inches.

In contrast, Zoysia grasses should be mowed at a height of 1-2 inches and can withstand up to three to four weeks without water before becoming dormant. Understanding the differences in maintenance requirements between these grasses is crucial when choosing the right lawn for your lifestyle and preferences.

Mowing Requirements

Zoysia grass requires more frequent mowing and a shorter mowing height than St. Augustine grass to maintain a healthy, lush lawn. St. Augustine grass should be mowed every 5-14 days to ensure the correct height, while Zoysia grass should be mowed between half an inch and one inch.

Keep in mind that the mowing frequency and height can impact the overall look and health of your lawn, so it’s essential to choose a grass that aligns with your maintenance preferences.

Fertilization Needs

When it comes to fertilization, Zoysia grass needs more attention than St. Augustine grass. To maintain a healthy and green Zoysia lawn, it’s important to fertilize the grass regularly, following the recommended schedule for your specific grass type.

In contrast, St. Augustine grass might not require as frequent fertilization, making it a more low-maintenance option for homeowners looking to reduce their lawn care tasks.

Watering Guidelines

Watering requirements for St. Augustine and Zoysia grass differ significantly. St. Augustine grass requires more consistent irrigation, needing approximately 34 inch of water twice per week for a total of about 1 12 inches of water per week.

Zoysia grass, on the other hand, is more drought-tolerant and can survive up to three to four weeks without water before becoming dormant. Consider your region’s typical weather patterns and your willingness to invest time and resources into watering when choosing between these grasses.

Tolerance Factors for St. Augustine and Zoysia Grass

St. Augustine and Zoysia grasses showcase different tolerance levels for shade, drought conditions, and foot traffic. St. Augustine grass is known for its salt and drought tolerance, as well as its ability to thrive in shady areas, with the ability to tolerate temperatures as low as 65 degrees Fahrenheit.

Zoysia grass, a versatile turf grass, is renowned for its durability and capacity to withstand various levels of foot traffic.

Understanding how zoysia grass lawns perform in terms of tolerance factors can help you make an informed decision based on the specific conditions of your zoysia grass lawn, making zoysia lawns an ideal choice for many homeowners.

Shade Tolerance

St. Augustine grass is more shade-tolerant than Zoysia grass, making it a better choice for lawns with a significant amount of shade. Zoysia grass, while still highly shade-tolerant for a warm-season grass, requires at least eight hours of bright full sun daily to thrive.

If your lawn has a mix of sun and shade throughout the day, consider how the shade tolerance of each grass type will impact the overall health and appearance of your lawn.

Drought Tolerance

When it comes to drought tolerance, St. Augustine grass is more resistant to drought than Zoysia grass and can maintain its color better when exposed to a lack of water. However, it’s important to note that when St. Augustine grass begins to turn brown, it’s an indication of dying, not dormancy.

In contrast, Zoysia grass:

  • is less drought-tolerant
  • uses rhizomes (below-ground runners sheltered from the sun and mower blades)
  • is more resistant to dry conditions than St. Augustine grass.

Foot Traffic Resistance

If your lawn is subjected to heavy foot traffic, Zoysia grass might be a better option due to its higher resistance to foot traffic compared to St. Augustine grass. Zoysia grass’s fine and smooth texture also makes it comfortable to walk on, perfect for yards that see a lot of activity.

Conversely, St. Augustine grass has a coarser texture and lower foot traffic tolerance, making it less suitable for lawns with heavy foot traffic.
