How to Deal With Nutgrass Problem around Swimming Pools

The preparation of a pool construction ground is important. Many have a notion that remnant vegetation dies upon the placement of a heavy structure. The large surface area of the pool structure, the weight it bears and light prevention will cause the vegetation to die. It’s just like placing a huge rock on a vegetation filled surface. The outcome is a humongous dead spot left. It is sensible to believe that placing a pool structure on a piece of vegetation will kill the plants.  Modern contractors do not overlook the vegetation on site. Necessary steps to ensure that no issues arise from the ground’s pool linear are important.

Effects of nutsedge

Nutsedge almost similar to nutgrass is a stubborn plant specie that is common in the southern parts of the US. Over time, it has become widespread and spotted in several other areas. Nutgrass flourishes in wet areas with soils rich in nutrients. After some time, it adapts to environmental changes. This means it can survive during droughts and in poor soils.

Nutsedge takes away nutrients and other necessities for crops and plants to thrive. If untreated, it can also maneuver its way through blocks made of rock, beds, and even plastic. When this happens, it creates a coat of mulch on these surfaces. In pools, it is no exception. It finds its way from the wall to the liner and penetrates to the other side of the liner. This can cause havoc as there is no solution to a pool hole filled with plants.

Difference between nutsedge and nutgrass

Most people tend to confuse nutgrass and nutsedge. For grass, they have hollow, soft round stems. That’s why it is easy to uproot grass. A Nutsedge is a sedge hence the name. Sedges are upright with firm stems and are triangular. These features make it stronger and difficult to uproot. Sedges have thick and stiff leaves. They also sprout and spread quickly compared to grass. This gives them the ability to permeate through surfaces.

Uprooting nutsedge does not eradicate the plant. A bulb will develop at the tip of the root allowing the plant to regrow again. Many refer to it as the nut of the plant earning it the name nutsedge. Nutsedge is usually tiny. Tuber, one of the species of nutsedge can have a diameter as big as one and a half-inch. Tubers are able to grow into a new plant regardless of whether fixed to the plant or not. They also can grow deep into the ground making it hard to have it eliminated in a pool site.

Eradicating Nutsedge

The most reliable way to get rid of nutsedge is to replace the soil. This can be difficult and impractical to homeowners. Another option is the use of glyphosate herbicide. This treatment weakens the stem of the plants causing the elimination of all the plants. It is important to note that it has little effect on the roots and the plants can regrow in the future. Another chemical, dichlobenil, is then added on the ground after the elimination of the plants. It is spread on the top layer of the soil to prevent future growth of the unwanted plants. Following the instructions to the letter will spare any effect on the existing vegetation.

How to apply Dichlobenil

The application of this dichlobenil should be before the installation of the pool or a vinyl liner. The site of the installation is first prepared. A hand spreader is convenient for it’s spreading around the areas the pool will cover. It’s further spread 2-3 feet beyond the perimeter of the pool. This is to prevent the long roots around the perimeter of the pool from sprouting into vegetation. It is then raked together with the soil to mix it. It is thereafter added water to allow it to disintegrate into dichlobenil crystals. The crystals create a barrier trapping any future germinating plant. The treatment is effective for 9-12 months.

If an area has a history of infestation of these nutsedge or if they exist in the neighboring land, contractors should not miss out on the ground preparation process. The process should continue even after the installation of the pool. This is to prevent any hidden developing roots in the surrounding areas from growing into a plant.
