Is it OK to Use Dehumidifier Water for Plants?

Dehumidifiers are a great tool for reducing excess moisture in your home. They work by pulling humidity out of the air and collecting it in a water tank. This begs the question: can you use the water collected in a dehumidifier for your plants?

The Pros of Using Dehumidifier Water for Plants

One of the primary benefits of using dehumidifier water for plants is that it's essentially distilled water. It contains very few minerals or additives, making it ideal for sensitive plants that may be susceptible to chemicals or hard water. Additionally, using dehumidifier water reduces the strain on municipal water supplies, which is an important consideration in areas prone to drought or water shortages.

Another benefit of using dehumidifier water is that it's free! Rather than dumping the water down the drain, you can repurpose it for your plants, reducing your water bill and decreasing your environmental impact.

The Cons of Using Dehumidifier Water for Plants

While using dehumidifier water for plants has several benefits, there are also some potential drawbacks to be aware of. The main concern is that dehumidifier water may not be safe for consumption, and therefore should not be used on edible plants. Additionally, dehumidifiers can accumulate bacteria or mold if they aren't cleaned regularly, which could harm your plants if not properly treated.

Another consideration is that dehumidifier water typically has a lower pH than tap water, which may not be suitable for all plant species. Acid-loving plants such as azaleas or blueberries may thrive with dehumidifier water, but others may suffer from acidic conditions.

Tips for Using Dehumidifier Water for Plants

If you decide to use dehumidifier water for your plants, there are several tips to keep in mind. First, make sure to clean your dehumidifier regularly to prevent the growth of bacteria or mold. You can do this by wiping down the tank with a solution of water and white vinegar or using a commercial cleaner designed for dehumidifiers.

Additionally, it's a good idea to test the pH of the dehumidifier water before using it on your plants. You can do this using a pH testing kit, which is available at most garden centers. If the pH is too low, you can adjust it by adding a small amount of lime to the water.

Finally, be mindful of the types of plants you're watering with dehumidifier water. While some plants may thrive with this type of water, others may not tolerate the acidity or lack of minerals. If in doubt, stick with tap water or consult with a gardening expert to determine the best watering strategy for your plants.

Conclusion

In summary, using dehumidifier water for plants can be a great way to conserve water and provide a source of clean, mineral-free water for your plants. However, it's important to be aware of the potential drawbacks and take precautions to ensure the safety and health of your plants. With these tips in mind, you can use dehumidifier water as a valuable resource in your gardening toolkit.
