Deep vertical mowing with tractor-mounted equipment (e.g., Graden, Sisis, First Products) can also be very effective in removing thatch from fairways. This process aggressively removes thatch and old plant material from the surface in addition to grooming the turf and promoting upright growth with less grain.Oct 1, 2012
Thatch is defined as the living and non-living material located between green turfgrass leaves and the underlying soil. Bermudagrass turf in the Florida Region accumulates a large amount of organic matter, and it is best to use the terms "thatch" and organic matter or "mat".Feb 27, 2015
Aeration, raking and lawn care The best way to get rid of thatch is regular aeration and good lawn care practices. Aeration should be done every year or two, depending on the severity of the thatch, the condition of the lawn and how much foot traffic there is on the grass. Aeration can be done in spring or fall.
Bentgrass. Available in several varieties, bentgrass is found on golf courses in cool summer or coastal locations, including in the North, Mid-Atlantic, coastal California and the Midwest.
Thatch is broken down by microbial activity. For microbes to work on thatch, there has to be enough moisture and oxygen in the layer. Topdressing opens the layer up to moisture and air movement and contributes microbes to the process. It is one of the most effective ways of controlling thatch.Nov 7, 2017
It is best to dethatch first before aerating your lawn. This way, you'll remove the excess debris and promote healthy root development. Aerating is best done when there's the problem of compaction.
Remove Lawn ThatchUse a thatch rake for thick layers of thatch. Using this tool in a push-pull motion will rip out thatch and dig into the soil. ... Use leaf rakes and a tarp to gather and remove the dead thatch and other material from your lawn. ... Water the lawn as needed to keep it moist and promote growth.
It can take a couple of years to fully break up the thatch, but it will happen. Here are some other factors and tips to help you get rid of thatch through decomposition: You need to keep the soil moist underneath the thatch layer. When it dries out, decomposition ceases.
Poa annua is easily the one best-known to golfers, primarily because of its use as the putting surfaces at Pebble Beach. Poa annua is a "warm-season grass," meaning it is a grass that grows better and healthier in warmer climates.Oct 31, 2019
Grasses are specifically selected for use on putting greens. Turfgrass breeders and natural selection have improved putting green grasses over many years. Bermudagrass, creeping bentgrass and Poa annua are the most commonly managed turfgrasses on putting greens in the United States.Feb 16, 2018

What is thatch? Thatch is a layer of organic material, such as dead grass stems and roots, which forms between the grass surface and the soil beneath. This material contains lignin, a compound which slows down its natural breakdown within the turf. Ideally, you need the soil fungi and other microbes to break down this material at ...
The Thatch-Away Supa-System from Greentek is used by leading golf courses worldwide to tackle the problems of thatch quickly and easily. Fully compatible with all popular green mowers, this innovative, cassette-based system is highly effective in tackling thatch, with tungsten-tipped blades penetrating even the most matted surfaces. Thatch-Aways cut out and collect thatch cleanly, leaving behind a perfectly groomed surface that is immediately playable. This world-leading technology can also be found in our Thatch-Away Walk Behind range for use in smaller areas, and top level courses who only use walk-behind equipment.
Up to a quarter of an inch of thatch can actually be beneficial to grass, depending on the desired playing characteristics, as it forms a protective layer over the soil that prevents it from drying out. This amount of thatch also makes the turf softer, cushioning the impact on the feet and bodies of sportspeople such as footballers, ...
What is the problem with thatch? Because thatch forms between the grass layer and the soil, it can prevent essential water and nutrients from reaching the soil. This makes the grass weak and easily damaged since the roots will tend to grow into the shallow thatch and not penetrate deeper into the soil below.
A shallow layer of thatch will also protect the new growth of grass shoots. However, any depth of thatch above a quarter of an inch is detrimental, particularly on golf greens where a firm fast surface is desired.
Thatch should be tackled as soon as the grass begins to grow strongly. For deep that problems use scarifiers, in the late spring, and early autumn.
It also makes the turf more vulnerable to changes in weather, becoming wetter during rainy spells and dryer in the summer months. With such shallow root growth, heavily thatched grass will quickly yellow and die during a dry spell, and will also be far less hardwearing for more physical sports.
The best way to get rid of thatch is to aeration regularly and to follow good lawn care practices. It is recommended that aeration be done every year or two, depending on the severity of the thatch, the condition of the lawn, and how much foot traffic there is on the grass. The spring or fall are the best times to aeration.
The buildup of thatch on turf is exacerbated by improper turf management, resulting in soft conditions. It is possible to accumulate rapid thatch accumulation due to excessive use of fertilizer and irrigation. In addition to grass species, other factors play a significant role as well.
To reduce the height of the turf, rake it to a height below.25 inches.
It is recommended to perform these programs annually, regardless of whether core aeration or vertical mowing is used. There are some golf courses that only need one cultivation event per year, while others require two or more.
If you use a thatch rake, you can rip out thatch and dig into the soil by pushing it in a push-pull motion.
If you are using a thatch rake or a stiff-tined rake, comb through the grass in a back-and-forth motion, applying enough pressure to reach the bottom layer of thatch and slightly penetrate the soil on a dry day.
In thatch buildup, the microbes in the soil are unable to break down organic matter as quickly as they accumulate it. In absence of beneficial microbes, excessive thatch is caused. Watering practices that are improper, such as too much or too frequently, can cause excessive thatch.
Thatch is defined as partly decomposed or undecomposed organic matter exclusively of plant origin.
Organic matter plays a pivotal role in golf course and general turf management through its influence on most processes that collectively determine 'turf health' or 'turf quality'. The changes in organic matter arising from turf management can critically affect the performance and sustainability of golf greens.
The forest litter contained the highest level of lignin, followed by the thatch layer from soil-based green and the pasture soils (Figure 3). Based on the lignin content it could be argued that the thatch material from the soil-based green is less degradable compared to that of sand-based green.
