There are some areas that have hard water, which has a high amount of minerals in it. In these areas, it is common to soften water. Softened water tastes better and is easier to deal with in the house, but what about with your plants in your garden. Is it ok to water plants with softened water?
What is Softened Water?
Softened water is water that has been treated, normally with sodium or potassium, to help remove minerals from hard water.
Can You Use Softened Water on Plants?
Most of the time it is not a good idea to water your garden with softened water. The reason for this is that softened water typically has a high amount of sodium, which is attained from salt. Most plants cannot tolerate high amounts of salt. The sodium in softened water actually interferes with the water balance in the plants and can kill plants by “fooling” them into thinking they have taken up more water than they have. Softened water essentially causes the plants in
Not only does the salt in softened water hurt the plants you water with it, the salt in the water will build up in your soil and will make it difficult for future plants to grow.
Soft Water Homes and Watering
This is not to say that if you have softened water you cannot water your garden and lawn. You have a few options if you have softened water.
First, you can have a bypass spigot installed. This means that you can have a special spigot installed on the exterior of your house that takes water from the water line before the water is treated in the water softener.
Second, you can try mixing your softened water with collected rainwater or distilled water. This dilutes the effects of the salt in your softened water and makes it less harmful to your plants. But be aware that the salt in softened water will still build up in the soil. It will be very important that you regularly test the soil for salt levels.
How to Treat Soil Affected by Softened Water
If you have soil that has been watered too much with softened water, you will need to work to correct the salt levels in the soil. There are no chemical ways to reduce the amount of salt in your soil, but you can do this manually by frequently watering the affected soil. This is called leaching.
Leaching will draw the salt out of the soil and will either push it deeper in the soil or will wash it away. While leaching will help to draw the salt out of the affected soil, it will also draw out nutrients and minerals that plants need to grow. This means that you need to make sure to add these nutrients and minerals back into the soil.
