Is Distilled Water Ok for Plants?

Water is a vital resource for plants, and gardeners want to make sure their plants have the best possible growing environment. One question gardeners often ask is whether distilled water is safe for plants.

The Pros of Using Distilled Water for Plants

Distilled water is pure water that has been created by boiling water and then capturing the steam. This process removes all impurities, including minerals and other substances that may be present in tap water, such as chlorine or fluoride. This makes distilled water a great option for plants that are sensitive to chemicals or minerals, such as orchids or terrarium plants. Using distilled water eliminates any harm that impurities in tap water could cause.

The Cons of Using Distilled Water for Plants

While distilled water may be great for some plants, others require minerals and other substances that are present in tap water. Plants that require calcium, magnesium, or potassium may suffer if they are given only distilled water. Additionally, since distilled water is free of any minerals, it has a neutral pH level. Some plants prefer slightly acidic or slightly alkaline soil, so using distilled water exclusively could upset the soil pH balance.

Using Distilled Water in Combination with Tap Water

A good option for gardeners may be to use a combination of distilled water and tap water. This would allow plants to receive the benefits of minerals present in tap water, while still eliminating any potential harmful substances. For example, a houseplant may be watered with tap water for one watering, and then with distilled water for the next watering. This would ensure a balanced water supply and pH balance for the plant.

Conclusion

Overall, whether distilled water is ok for plants depends on the specific needs of the plant. While some plants benefit from the purity of distilled water, others require minerals and other substances present in tap water. Gardeners may want to consider using a combination of distilled water and tap water to provide a balanced water supply and optimal growing environment for their plants.
