Will a Swimming Pool Kill Grass and Surrounding Landscape?

When it comes to planning out your dream backyard equipped with a brand-new swimming pool, you might have thought to yourself once or twice if a pool will kill the surrounding landscape. Whether you’re concerned with the actual pool structure itself or the water and chemicals in the pool and how they could affect your grass or garden, there are a few important things to keep in mind.

Will a Swimming Pool Kill My Grass?

If you’re looking to install an above-ground pool, you should expect the specific sections of the natural grass under the pool to be affected. If you’re setting up your pool to remain in this area permanently, this is something to anticipate. Ultimately, you can think about it similarly to installing an in-ground pool, in which you would need to excavate a hole. Because this specific area of your yard will be housing a pool, whether above or below ground, the earth that it rests upon will be affected. However, artificial grass, on the other hand, experiences no change. Even if chemicals or water get onto artificial grass, for instance, you won’t need to worry about mud, a change in colour, or any other issues. Of course, an above-ground pool on artificial grass will flatten the blades, but this is something that can be easily fixed if you decide to take your pool out at any point. Simply brush the grass back up into place and give it some time to adjust. It should be back to normal in no time.

It’s safe to say that any heavy object that rests upon natural grass for long enough will have its effects. Because grass needs water, sunlight, carbon dioxide and space to grow, inevitably, your natural grass won’t survive under a permanent pool structure.

However, when it comes down to it, the condition of the land itself under your swimming pool is a far more important aspect to consider. Therefore, before planning your above-ground pool installation, it’s vital to ensure that the ground is level and stable. This will often require the addition of concrete pads, sand, solid foam, or flooring underlay, just to name a few. By prioritizing that the ground beneath your swimming pool provides the necessary support, you’re ensuring that the safety of your swimmers, neighbours and homes are all taken into consideration first and foremost.

Can Pool Water and Chemicals Damage Your Landscaping?

Because most soil can withstand acidic levels, it is actually pretty unlikely that chlorine will affect grass or surrounding greenery. For instance, say your children are playing in the pool, and the water splashes outside of it. There’s no need to worry! Although some people might assume that chlorine will harm your grass, this shouldn’t be an issue because it is diluted in the pool’s water.

Now, you might be asking yourself, what about pool water in large quantities? Say, for instance, you’re planning on draining your pool and need to run a line across your grass in order to do so. We would recommend that before draining a pool, you try to neutralize the pH as much as possible. This can be achieved by stopping any addition of chlorine or other chemicals days leading up to the draining process.

Although it makes the most sense not to continue adding chemicals if you know you will be closing your pool for the winter, doing a quick reading of your pH levels before draining is still a wise decision. This will allow you to see how acidic your pool water is, as high acidity levels can destroy plants and landscaping. Not only is this step necessary for the health of your yard and garden, but it is also important for the community as a whole.

When draining your pool into a side gutter, it’s important to remember that the filtration in these systems is not like one you would see in a sanitary sewer water treatment. Therefore, it’s also best to ensure that you reduce the number of chemicals in your pool water before draining it for the health and safety of all those around. If you have any questions about how to drain your pool properly, you can reach out to a swimming pool provider near you.

Although many people might assume that simple day-to-day use of your pool can destroy the surrounding grass or landscaping, it’s important to remember that the earth can withstand more than we might think. In small, diluted quantities of water, chlorine interacting with the grass and gardens surrounding your pool shouldn’t be an issue to worry about.
