How Thick Is St. Augustine Sod?

Sod Thickness

• The thickness of St. Augustine sod is among the factors that need to be taken into account at the time of sod selection. The usual depth of sod is 1/4 to 1/2 inch, according to the Purdue Department of Agronomy. Sod that has been harvested properly should contain little soil. This not only makes the sod easier to transport and lay but also helps roots establish more rapidly.

Sod Selection

• When selecting St. Augustine sod, choose soil similar to the intended planting site. Well-matched soil reduces possible problems with layering or compaction and ensures healthy water flow. The Purdue Department of Agronomy recommends inspecting the site where the sod is harvested as this gives an idea of the soil type and the health of the sod. Healthy sod has a dark green color, is moist but not wet, and has no weeds or yellow grass patches.

Growth Requirements

• St. Augustine grass adapts well to a wide range of fertile, well-drained soil types with pH of 5.0 to 8.5. Avoid planting in pH over 7.5 as this produces chlorosis or yellowing in the grass. The grass is highly tolerant of hot summer weather and is moderately tolerant of shade. St. Augustine grass is poorly tolerant of compacted and poorly drained ground.

Sod-Laying Tips

• The Purdue Department of Agronomy recommends laying St. Augustine or any grass sod within 24 hours of being cut. Do not let the sod dry out. If the sod cannot be laid in time, sprinkle water on the outer rolls to keep them from drying out. Moisten the soil on site before laying the sod and lay the sod in a staggered, brick-like fashion. Do not stretch or overlap the sod as this leads to shrinking and exposed ground later. Water the lawn regularly until the sod is well-rooted and avoid walking on sod until grass starts to grow actively, recommends the University of Florida Extension.
