Should I Water My Plants with Distilled Water?

Many people believe that using distilled water for watering plants is a good idea because it removes impurities and minerals that can harm the plant. However, this might not always be the case. In this article, we’ll explore whether or not you should water your plants with distilled water.

What is Distilled Water?

Distilled water is water that has been purified through a distillation process. The process involves boiling the water and then collecting the steam, which is then condensed back into liquid form. During this process, minerals and impurities are left behind, resulting in water that is almost entirely pure H2O.

The Pros of Using Distilled Water for Your Plants

One of the most significant benefits of using distilled water for your plants is that it is free from the impurities that can be found in tap water. These impurities, including minerals and dissolved solids, can cause harm to plants over time. By using distilled water, you’re eliminating these impurities, which can lead to healthier and more vibrant plants.

Distilled water doesn't contain any chlorine or fluoride, which can also cause harm to plants. This is particularly true for sensitive plants, including tropical plants and orchids.

The Cons of Using Distilled Water for Your Plants

While distilled water has many benefits, it also has some drawbacks. One of the most significant drawbacks is that it is entirely devoid of minerals. These minerals, including calcium, magnesium, and potassium, are essential for plant growth and development.

Plants require these minerals for various processes, including cell division and photosynthesis. Without minerals, plants can become stunted or show signs of deficiency, including yellowing leaves and poor growth.

The Bottom Line

So, should you water your plants with distilled water? As with many things in life, the answer is not straightforward. While distilled water can be useful for eliminating impurities and harmful chemicals, it doesn't contain the minerals that plants need to thrive.

If you decide to use distilled water, it’s essential to provide your plants with a source of minerals. You can do this by adding a plant-specific fertilizer to the water or by using an alkaline mineral supplement, such as rock dust.

Overall, it’s best to use a combination of distilled and tap water for your plants. By doing so, you can benefit from the advantages of both while also ensuring that your plants have access to the minerals they need for optimal growth and health.

Final Thoughts

Whether or not you should water your plants with distilled water ultimately depends on your specific plants' needs. If you have plants that are sensitive to impurities or chemicals, distilled water can be an excellent option. However, if your plants require essential minerals, you'll need to provide them with a source of these nutrients.

By considering your plants' specific requirements and using a combination of distilled and tap water, you can ensure that your plants thrive and grow to their full potential.
