How to Water Plants if You Have a Water Softener

If you have a water softener installed in your home, you may be wondering if it's safe to use that water to irrigate your plants. Water softeners remove minerals from the water, but can also add sodium, which can be harmful to some plants. Here are some ways to safely water your plants with softened water.

Check the Sodium Level

Before using your softened water on your plants, you should check the sodium level. You can purchase test kits online or at your local garden center. If the sodium level is higher than 70mg/L, it's not recommended to use the water on your plants. If the sodium level is lower, you can proceed cautiously.

Dilute the Water

If you want to use softened water on your plants but the sodium levels are too high, you can dilute the water with regular tap water. Mix three parts softened water with one part tap water to reduce the sodium levels. You can increase the ratio of tap water as needed.

Use a Rain Barrel

If you have a rain barrel, you can collect rainwater to use on your plants. This water is naturally free of minerals and chemicals, and is safe for all plants. You can also use this water to dilute softened water, if needed.

Choose Plants That Are Tolerant to Salt

If you have high levels of sodium in your softened water and don't want to dilute it, you can choose plants that are tolerant to salt. These plants have adapted to growing in salty environments and can handle higher levels of sodium. Some examples of salt-tolerant plants include succulents, yucca, and sea lavender.

Flush Your Soil

Over time, sodium can build up in your soil and harm your plants. Flushing your soil with fresh water can help reduce sodium levels. You can do this by watering your plants with tap water once a month or using a flushing solution specifically designed for plants.

Final Tips

When watering your plants, try to avoid getting the water on the foliage. Softened water can leave spots on the leaves, and salt-tolerant plants are usually sensitive to salt on their leaves. Watering at the base of the plant is better for the roots anyway.

Another tip is to use a watering can instead of a hose. A watering can allows for more control and precision, so you can avoid overwatering your plants and prevent salt buildup in the soil.

By following these tips, you can safely use softened water to water your plants. Remember to always check the sodium levels, and if in doubt, dilute the water or choose salt-tolerant plants.
