How Are St Augustine Plugs Different From Sods?

Augustine grass plugs are smaller in size and much less expensive when compared to grass sods. Sods require extensive soil preparation beforehand and might need professional help for installation. Grass in plug form takes roots much quicker than sod form.

Plugs vary from seller to seller but, on average, measure about two to three inches in length and width. Depending on the dimensions of your lawn, you need to buy the right number of plugs. 

– Distance Kept

Each plug needs to be planted at a distance of about 10 to 12 inches from the next ones on all sides. Keep in mind that plugs need to be installed in the lawn along with the soil.

On the other hand, it is also a much more viable option for those with a very large lawn when buying an entire turf would become too expensive. In fact, for a medium-sized lawn, buying plugs costs at least six to seven times less than a sod type would.

– Take Root Easily

Not all grasses behave the same when grown and sold in plug forms. Grass species that do not grow via stolons are not good at growing via plugs. The good news is that St Augustine is not one of them. It does extremely well in plug form and establishes very quickly in the lawn. 

Plugs are also quick to take root in the soil compared to other types, which means that in a fast pace, you will have a grass that is very well established and fixed. Because they do not already have a proper layer of soil underneath, it tends to stay a little more challenging. In short, the grass in plug form, is a type that you would invest in which is characterized by how it hates its confined nature and is quick to take root whenever planted on the lawn.

Unlike plugs, sod cannot be placed over the soil and is expected to take root. Proper soil preparation is required before sod can be laid over the lawn; otherwise, it won’t take root, and the money spent on it will go to waste.

The first step you must take in this situation is to clean your lawn of all the debris present over it. Anything bigger than two to three inches, like rocks, stones, and twigs, must be cleaned off the lawn. This is essential because you want it to have a proper grip, or a healthy establishment when you are adjusting it.

You need to grade the lawn and create a drainage path away from your house. If the lawn is already sloped, then this needs to be reduced. Which means that you can use hand-held tools for grading smaller areas, while a tractor-mounted blade will be needed for a larger lawn.

Next, you must either till the soil up to a depth of two to four inches or carry out proper soil aeration. Aeration followed by tilling will also get rid of weeds and improve drainage. On the other hand, don’t forget that you must also test the soil to see if it needs amendment, then add premium-quality topsoil. The most important step is to use a roller to flatten the surface of the lawn so that sod attaches properly to it.

– No Time Needed For Fill-In

Unlike other types, if you invest in sods, they are ones that come in a single carpet like a roll of soil and grass. It is bought the same size as the lawn and then cut according to its exact curves and corners. After you have prepared the soil well and placed sod over it, you instantaneously get a yard full of grass. 

No Time Needed For Fill In the Sod

– Very Expensive

When you decide to plant St Augustine, be ready to spend a fortune on it compared to plugs of grass. On average, the sods of this grass cost at least three to four times as much as buying plugs needed to cover the same area. Although you will have a proper fitting option, but it is going to be heavy for your pocket, which means if you have a tight budget, you should think twice. 

Afterward, you also need to add in the cost of the extensive lawn preparation required before sod can be installed. Sod is also not easy to establish all by yourself either. You will likely need professional sod installers to place sod on the lawn.
