Houseplants are more than just decoration – they’re part of the family for many plant lovers. From monstera deliciosa to spiky snake plants, these leafy companions bring life to our homes and often earn affectionate nicknames like “Christofern” or “Flaura Croft.” But keeping them happy and healthy can lead to some important questions, like whether distilled water is a good choice for watering them.
If you’re wondering whether distilled water is the best option for your plants, you’re not alone. Distilled water has its pros and cons, and its suitability depends on the type of water your plants need. Let’s dive into everything you need to know about distilled water to help keep your houseplants thriving.
In this article:
Understanding Distilled Water
What is Distilled Water?
Distilled water is a type of purified water achieved by boiling water and then condensing the vapor. This process removes impurities, contaminants, and minerals, leaving the water pure. Many plant owners choose distilled water for watering houseplants because it lacks harmful additives like chlorine and fluoride.
How is Distilled Water Made?
Distilling water involves boiling it to create steam and then condensing the steam back into liquid form. This process reduces impurities and contaminants, ensuring the water is chemical-free and ideal for sensitive plants. The remaining liquid in the boiling pot often contains heavy metals and should be discarded.
Why Distilled Water for Plants?
Is distilled water good for plants? The jury is divided. Using distilled water reduces the risk of harmful chemical buildup, ensuring a clean water source for your plants. Sensitive indoor plants, such as orchids and dracaena, benefit greatly from distilled water.
Plants need minerals like calcium and magnesium, which are often present in tap water. However, excessive concentrations of fluoride and other additives in tap water can harm certain plants. For these reasons, distilled water is often considered one of the best water options for specific plant care needs.
The Impact of Distilled Water on Plants
Is distilled water the secret to thriving plants? Maybe, but it’s not a one-size-fits-all solution.
Benefits of Using Distilled Water on Plants
-
- Free of Contaminants: Distilled water doesn’t contain harmful chemicals, making it a safe option for indoor plants.
-
- Prevents Toxic Buildup: Using distilled water prevents mineral buildup in soil, which can harm plant growth over time.
-
- Mimics Natural Environments: Plants like orchids and Venus flytraps thrive with distilled water, which closely resembles rainwater.
Potential Drawbacks of Using Distilled Water on Plants
-
- Lacks Essential Minerals: Distilled water doesn’t contain calcium or magnesium, which are vital for plant health.
-
- Cost and Maintenance: Regularly using distilled water can be expensive and requires adding nutrients manually to support plant growth.
When Should You Use Distilled Water for Plants?
Distilled water is ideal for:
-
- Indoor Plants: Prevents harmful mineral buildup in potted plants.
-
- Sensitive Plants: Houseplants like orchids, ferns, and dracaena thrive with distilled water.
- Seed Germination: Provides a pure environment for sprouting seeds.
Comparing Water Sources
| Water Source | Pros | Cons |
| Tap Water | Readily available, contains minerals | May have chlorine or fluoride & be harmful to plants |
| Distilled Water | Free of contaminants, suitable for sensitive plants | Lacks essential minerals |
| Filtered Water | Reduces harmful substances, retains some minerals | Slightly more effort to access |
| Rainwater | Natural and nutrient-rich | Availability depends on the weather |
Using Distilled Water Effectively for Plants
Follow these tips for watering plants with distilled water:
- Reintroduce Nutrients: Add diluted fertilizer to compensate for the lack of calcium and magnesium.
- Alternate Water Sources: Combine distilled water with rainwater to help balance nutrient levels.
- Monitor Watering Frequency: Avoid overwatering plants to prevent root rot.
- Enhance with Household Items: Boost plant health by adding nutrient-rich, natural additives to distilled water:
- Coffee Grounds: Add a small amount of diluted coffee grounds for a nitrogen boost, ideal for acid-loving plants like azaleas and hydrangeas.
- Ground Eggshells: Blend or crush eggshells and soak them in water to add calcium for stronger roots and stems.
- Blended Banana Peels: Mix blended banana peels with distilled water for potassium and phosphorus to promote flowering and growth.
- Epsom Salt: Dissolve a teaspoon of Epsom salt into distilled water to add magnesium, which enhances photosynthesis and leaf development.
- Aloe Vera Gel: Mix a teaspoon of aloe vera gel with distilled water to boost plant resilience and hydration.
Common Myths and Misconceptions
Myth: Distilled Water Makes Plants Grow Faster
While distilled water prevents chemical buildup, it doesn’t inherently accelerate plant growth unless supplemented with nutrients.
Myth: Distilled Water Harms Plants in the Long Run
Distilled water doesn’t harm plants when used appropriately and paired with proper fertilization.
Additional Tips for Enhancing Plant Water
- Let Tap Water Evaporate: Allow tap water to sit for 24 hours to reduce chlorine levels.
- Use a Water Filter: Filtered water enhances overall water quality.
- Test pH Levels: pH can impact water quality and the suitability of your water supply.
- Collect Rainwater: Use rainwater for outdoor plants or mix it with distilled water for indoor use.
- Address Hard Water: Over time, hard water can leave mineral deposits in soil; if this is an issue in your area, consider filtration or using distilled water.
- Consider Spring Water: Spring water can be a good option for plants, as it often contains beneficial minerals; however, always check its pH and mineral content to ensure it suits your plant’s needs.
Frequently Asked Questions
Do plants grow better with tap water or distilled water?
Plants grow better with the type of water that suits their needs. Distilled water is ideal for houseplants that are sensitive to contaminants like chlorine and fluoride found in tap water. However, hardy plants may thrive with drinking water, which provides essential minerals like calcium and magnesium ions that support plant health.
Which plants like distilled water?
Plants such as orchids, ferns, and carnivorous varieties benefit greatly from distilled water. These species are sensitive to the additives and impurities in tap water and thrive in environments with pure water, free of heavy metals and fluoride.
Is bottled water good for plants?
Bottled water can be used for plants but may contain minerals or additives that aren’t ideal for sensitive houseplants. For consistent plant care, distilled or filtered water is a better choice to avoid the potential build-up of unwanted substances.
How do you make tap water safe for plants?
To make tap water safe for watering plants, let it sit for 24 hours to evaporate chlorine and reduce harmful additives. Alternatively, use a water filter to reduce impurities while retaining beneficial minerals like calcium and magnesium.
