Softened water is treated to remove hard minerals like calcium and magnesium, but in most systems, those minerals are replaced with sodium. While this is beneficial for protecting plumbing and appliances, that added sodium can be problematic for plants—especially when used regularly for watering lawns, gardens, or indoor plants.
In Fredericksburg and across the Texas Hill Country, many homeowners rely on water softeners due to naturally hard water. When softened water is used on plants, sodium can build up in the soil, making it harder for roots to absorb water and nutrients. Over time, this can lead to poor growth, yellowing leaves, or even plant death. Sensitive plants and vegetable gardens tend to show damage first.
For this reason, it’s generally recommended to use untreated outdoor water spigots, rainwater, or bypassed water for irrigation. At 72 Degrees Air Conditioning, Heating, and Plumbing, we help homeowners set up water softener systems that protect plumbing while still supporting healthy landscaping.
