With summer well underway in many parts of the world, it’s time to start thinking about ways to keep your lawn and garden looking lush and green. One way to do this is by using a sprinkler system for watering.

But have you ever stopped to think about what kind of chemicals might be lurking in that water? Let’s dive into what kind of chemicals could be present in a sprinkle and how they can affect your garden.

Chemical-based Sprinklers

Most commercially available sprinklers that use chemical-based solutions will advertise them prominently on the packaging. These chemical-based solutions may include phosphates, chloramines, and chlorine. Chlorine is used as a disinfectant for drinking water but it has some drawbacks when used in a sprinkler system.

It is known to deplete essential vitamins and minerals from plants, leading to potential nutrient deficiencies in the soils near your home.

Sodium and potassium may also be used to help the water better penetrate the soil and reach its intended destination. However, these chemicals can also leave a residue that could cause discoloration on a lawn or even damage plants if used too frequently or at too high concentrations.

If you plan on using chemical-based solutions, it’s important to understand what ingredients are being used and follow any instructions on their application carefully.

Non-Chemical Sprinklers

If you’re concerned about any potential health risks associated with chemical-based systems, there are other options available such as non-chemical based sprinklers that use natural sources like rainwater or collected groundwater instead of treated tap water.

These systems may still require some maintenance but they will reduce any risk associated with chemical exposure as well as help conserve precious resources like water—a win/win situation all around!


By now you should have a good idea of what kind of chemicals might be lurking in your sprinkler system and how they can affect your garden or landscape.

While there are plenty of chemical-based options available for watering your lawn or garden, there are also non-chemical based options that may be more beneficial for both you and the environment.

So get out there and make sure you’re giving your lawn or garden the right kind of shower!
