Watering Plants: Protecting Them from Soft Water Damage

Plants require the right balance of nutrients and water to thrive. However, using soft water for irrigation can have detrimental effects. Softened water, which contains high amounts of salt, disrupts the natural water balance of plants. Sodium in salt tricks the plants into thinking they are receiving more water than they actually are, resulting in a slow death from thirst.

Protecting Plants from Soft Water Damage

Fortunately, there are ways to mitigate the negative effects of soft water on plants without compromising its use for personal needs.

1. Mixing Rainwater with Softened Water

One effective solution is to collect rainwater in a barrel and mix it with softened water. By combining fresh rainwater with soft water, the sodium content is diluted, reducing the damage caused to plants. In regions with limited rainfall, using distilled water as an alternative can also help.

2. Bypassing the Soft-Water Line

Another option is to have a separate faucet or outdoor spigot connected directly to the main water supply, bypassing the soft-water line. This simple adjustment allows you to use unsoftened water for plant irrigation while still utilizing the benefits of a full-house water softener. Inform the water softening company about your preference for a separate water supply for irrigation purposes.

Restoring Soil Compromised by Softened Water

Different regions have varying degrees of water hardness, making water softening a necessity in some areas. However, if you believe your soil has been negatively affected by repeated exposure to soft water, there are measures you can take to restore its health.

To determine if your soil is affected, test its pH balance and check for excessive alkalinity. Certain plants, like azaleas, caladiums, and begonias, may not grow well in hard water. In such cases, consider using water produced through reverse osmosis. Many gardeners believe this type of water provides ideal nutrient flow for plants, particularly delicate ones.

Reversing the Damage: Leaching

If you suspect your yard or garden has been treated repeatedly with soft water, you can reverse the damage through a process called leaching. Leaching involves saturating the soil with unsoftened water to wash away the salt buildup caused by softened water. However, it’s crucial to replenish any minerals that might have been washed away in the process.

While occasional watering with softened water won’t harm trees and soil, it should not become a habit. If you notice a decline in the health of your plants, have your soil tested for pH imbalance and your water tested for excessive hard-water minerals. Achieving a balance between soft water and rainwater can significantly improve the condition of your plants.

Remember, maintaining the right water balance can be challenging. For indoor use, keep softened water available, while using natural well water or rainwater for watering lawns, trees, and gardens. Pay attention to areas that seem less productive than others, as the water balance can vary across your property depending on past care and conditions. Watering is an essential part of plant care, so finding the right balance is key.
