Safe and Eco-Friendly: Using Dishwasher Water for Your Kitchen Garden

With the increasing awareness about water conservation and eco-friendly practices, many homeowners are looking for ways to reuse and recycle water. One such method is using dishwasher water for your kitchen garden. But is this practice safe? And what kind of dishwashing liquids should be used? This article will delve into these questions and provide you with comprehensive answers.

Is Dishwasher Water Safe for Your Kitchen Garden?

Yes, dishwasher water can be safe for your kitchen garden, but with some caveats. This water, also known as greywater, is lightly used water from your home’s sinks, showers, and washing machines. It may contain traces of food, grease, cleaning products, and other impurities. While it’s not potable, it can be used for irrigation purposes.

However, not all dishwasher water is safe. If the water contains high levels of grease, food particles, or harsh cleaning chemicals, it can harm your plants. Therefore, it’s crucial to use eco-friendly dishwashing liquids and ensure the water is adequately filtered before using it in your garden.

Using Eco-Friendly Dishwashing Liquids

When using dishwasher water for your kitchen garden, it’s essential to use eco-friendly dishwashing liquids. These products are free from harsh chemicals that can harm your plants and the environment. They are biodegradable, non-toxic, and safe for all types of plants.

Some popular eco-friendly dishwashing liquids include Seventh Generation, Ecover, and Method. These brands are known for their plant-based ingredients and commitment to environmental sustainability.

How to Use Dishwasher Water in Your Kitchen Garden

Using dishwasher water in your kitchen garden requires some planning and preparation. Here are the steps you should follow:

  • First, ensure your dishwasher is connected to a greywater system. This system collects, filters, and distributes the water to your garden.

  • Use only eco-friendly dishwashing liquids. Avoid products with bleach, boron, or other harmful chemicals.

  • Do not use dishwasher water if you’ve washed dishes used for meat preparation. This water can contain harmful bacteria.

  • Use the water for irrigation purposes only. Do not use it to water edible parts of plants.


Using dishwasher water for your kitchen garden can be a safe and eco-friendly practice if done correctly. By choosing the right dishwashing liquids and following the proper steps, you can conserve water and contribute to a healthier environment. However, always remember to monitor your plants for any signs of distress and adjust your practices as necessary.
