If you see a beautiful lawn in the neighborhood with a dark green look, they likely have some St. Augustine grass on the lawn. It is among the most beautiful lawn options and is mostly found in the tropical and subtropical regions. We shall talk more about the origin and spread of the grass in another post.

However, keeping your lawn beautiful with it takes some bit of work (It is not your usual lawn vegetation). It needs regular maintenance, mainly because it grows pretty fast in warm weather conditions. There are several ways to maintain Saint Augustine grass, including mowing, sodding, aerating, watering, fertilizing, and dethatching. Today, our focus will be on dethatching and, in particular, everything you need to know when it comes to dethatching St Augustine grass.

Well, let us begin by shedding some light on what thatch is. Thatch is a load of dead plant material usually found on top of the soil. It protects direct sunlight from reaching the surface of your lawn and serves as a source of manure.

Dead thatch can help retain nutrients in the soil, but an excessive layer of thatch could affect overall growth. It tends to restrict moisture and other essential elements for the healthy and quick growth of your Turf. In turn, the grass begins to root within the thatch while fighting to obtain these elements. That is not what you want.

Moreover, a lawn with a thick layer of thatch is usually quite challenging to maintain and is quite vulnerable to adverse weather effects. But letโ€™s get to that a little bit later in this piece.

What is the Role of a Dethatcher?

Firstly, a dethatcher is also known as verticutter, and it uses several vertically placed blades to cut the thatch layer. As the name suggests, a dethatcher plays the role of getting rid of dead plants and roots, forming a layer between vegetation and the soil.

How Regularly Should You Dethatch Your Turf?

Generally, a lawn needs dethatching at least once in a year. Precisely, the accurate way to know when some dethatching is needed is by checking if the thatch layer has grown beyond ยฝ an inch. When it comes to St Augustine thatch, we recommend dethatching early in the spring.

Fertilize

With a thick layer of thatch, it is definite that this best grass for clay soil is famished of growth nutrients. Hence, you can use a slow-release fertilizer with phosphorous, nitrogen, and potassium portions to heal the vegetation.

Mowing

Mowing has a significant role to play in the growth of your lawn. Once you dethatch St Augustine, ensure that you continue mowing to enhance new grass growth. Beware that mowing can adversely affect growth.

Treat for Weeds

We all know that bare soil is usually an invitation for weed growth. After dethatching, you will realize that weeds will be competing for space with your grass. If you do not deal with them in good time, your efforts will be in vain. Always have a pre-emergent weed killer to do away with the weeds attempting to germinate during the grassโ€™s recovery period.
