Will Softened Water Hurt Plants?

Water is essential to plants as it aids in the growth and maintenance of a healthy plant. However, not all water is the same. Some plants require specific types of water, and the wrong type can harm the plant. One such type of water is softened water.

What is Softened Water?

Softened water is water that has undergone a process called ion exchange. This process removes hard water minerals such as calcium and magnesium, making the water “soft”. The water is then treated with salt to remove any remaining minerals before being used.

Why Do People Use Softened Water?

People use softened water for a variety of reasons. One reason is that it can prolong the life of household appliances such as washing machines and dishwashers. Hard water minerals can cause a buildup of scale and can be damaging to these machines. Softened water can also help reduce soap scum and leave clothes and dishes feeling cleaner.

How Does Softened Water Affect Plants?

While softened water may be beneficial to household appliances, it can be harmful to plants. Softened water contains a high level of sodium, which can be toxic to plants. Sodium can accumulate in the soil and cause soil salinity, which can inhibit the plant’s ability to absorb moisture and nutrients. Additionally, the lack of calcium and magnesium in softened water can also impact plant growth, as these minerals are essential to plant development.

Which Plants are Affected?

Some plants are more sensitive to softened water than others. Plants that are most affected include those that are sensitive to salt and those that prefer acidic soil. These include ferns, spider plants, and begonias, among others. However, even plants that are not sensitive to salt can be affected by the lack of essential minerals in softened water.

What Can You Do?

If you use softened water, there are several things you can do to minimize the impact on your plants. One solution is to mix softened water with rainwater or tap water to dilute the sodium levels. Another option is to use a water filter system that removes sodium and adds back in calcium and magnesium. Additionally, you can collect rainwater and use it to water your plants. Rainwater is naturally soft and free of harmful minerals.

In Conclusion

In conclusion, while softened water may be beneficial for household appliances, it should not be used to water plants. The high level of sodium and lack of essential minerals can harm plant growth and development. If you must use softened water, dilute it with rainwater or tap water, use a water filter system, or collect rainwater to water your plants. By taking these steps, you can ensure that your plants remain healthy and thrive.
