Is Softened Water Safe for Your Houseplants?

As a homeowner with a green thumb, you might be wondering if the softened water from your water softener is safe for watering plants. After all, house plants are not just decorative elements; they’re living organisms that require specific care to thrive. The type of water you use can significantly impact their health. So, let’s examine the question “Is softened water safe for your houseplants?” more closely.

Soft Water & Your Houseplants

Soft water is water that has undergone a water treatment process to remove high levels of calcium and magnesium, which cause hardness. A water softener achieves this by replacing these minerals with sodium or potassium ions through a process called ion exchange.

While soft water is excellent for household use, offering benefits like better soap lathering and preventing scale buildup in pipes and appliances, its suitability for watering plants is a subject of debate. House plants, like all living things, need a balanced diet to grow and thrive. This includes a variety of nutrients and minerals, many of which are found in water.

When we use soft water on plants, there’s a concern that the sodium content in the softened water might be harmful to them. Too much sodium can interfere with a plant’s ability to absorb water and nutrients, leading to stunted growth, yellowing leaves, or even plant death in severe cases.

Moreover, by removing calcium and magnesium — both of which are essential nutrients for plant growth — softened water may deprive your plants of necessary nourishment.

In contrast to softened water, untreated water, such as tap water, can contain a mix of minerals that are beneficial to plants. These minerals include calcium and magnesium, which contribute to cell wall structure and photosynthesis, respectively. However, if your tap water is too hard, it might lead to mineral buildup in the soil, which can also harm your plants. So, while untreated water might seem like a better option, it’s not without its potential drawbacks.

Alternatives for Watering Plants

If you’re concerned about using softened water for your house plants, there are alternatives you can consider. One of the most popular is reverse osmosis water.

A reverse osmosis system is a type of filtration system that removes the majority of contaminants from water, including sodium. It produces pure, almost mineral-free water, which is safe for most houseplants. At Serv-All Water Conditioning, we’d be happy to help you select the ideal reverse osmosis system for your household.

Distilled water is another option. Similar to reverse osmosis water, distilled water has gone through a process to remove impurities. In this case, the water is boiled into steam and then condensed back into liquid form in a separate container. This process leaves behind all minerals and impurities, resulting in highly pure water.

While distilled water is safe for plants, it also lacks the essential minerals found in tap water. So, like with reverse osmosis water, if you choose to use distilled water, you may need to supplement your plants with additional nutrients.

If you don’t have access to a reverse osmosis or distillation system, and collecting rainwater isn’t an option, consider using bottled spring water. Spring water is naturally filtered as it flows underground and typically contains a balanced level of minerals beneficial to plant growth. However, keep in mind that bottled water can be more expensive and less environmentally friendly than other options.
