Distilled water is soft water without the trace amounts of sodium left by a mechanical softener. Using distilled water for indoor plants provides a safe and impurity-free source of irrigation that can prevent any toxicity from chemical or mineral buildup. It's also free of contaminants like bacteria.
While watering your yard plants with bottled water may be impractical, using bottled spring water for your indoor plants will make a big difference for them. To give your plants the absolute best, rainwater and bottled spring water are your best options. Any water containing sugar or salt will hurt them!
Distilled water is healthy for your houseplants because it's free from chemicals, metals, and other impurities. But—distilled water also eliminates beneficial minerals, so your plants won't grow as quickly as with rainwater or filtered water.
In side-by-side comparisons, plants watered using distilled water tend to grow faster and stronger than those watered with tap water. We find it the “Best Water for Indoor Plants.” Plants watered with distilled pure water usually produce more leaves and grow more vigorously.
Pro: Bottled water can be a great alternative to tap water, if the local water is not safe for plants. If bottled water is the easiest option for you, try to use bottled spring water as it contains natural minerals that help plants grow.
Purified water is great for plants as it is void of any harmful bacteria or contaminants that can cause common plant problems like root rot and fungal diseases. Purified water is accessible and often inexpensive, and works well for almost all plants.
If you're distilling your own water from your tap, those types of contaminants shouldn't be an issue. So, yes you can use distilled water to give your plants, but the good minerals that help keep the plant healthy and growing have been removed.
Run your sink into a watering can, cup, or bucket, and let it sit for a good 24 hours. This will allow chemicals like chlorine and fluoride the time to evaporate from the water. We like to have a full watering can ready to go with still water so that if our soil seems dry, we can water our plant without waiting a day.
Some parts are particularly sensitive to specific chemicals found in tap water. Fluoride is damaging to spider plants, corn plants, prayer-plants, dracaena, and peace lilies.
Distilled water is also a good choice and is easy to find at most grocery stores. Finally, you can also use a reverse osmosis filter to make tap water safe for your plants. This type of filter will remove nearly all contaminants from the water, leaving your plants with clean, safe water that won't harm them.
Results: The rainwater and bottled spring water are great at helping plants grow, but the sugar water and salt water actually hurt growing plants. Tap water and distilled water may not hurt the plants, but you'll notice they don't grow as tall and proud as the plants that were fed rain and spring water.
Chlorine and fluoride
Ordinary tap water, well water, rain water, and snow melt are all okay to use if warmed to room temperature. Chlorine added to drinking water does not harm most plants but some may develop brown leaf tips over an extended period of use.
If you want to try watering plants with distilled water, you can purchase it at most grocery stores or make your own. You can buy a distillation kit, often found in sporting goods departments or do it with common household items.
As the theory goes, soaking banana peels releases nutrients like potassium and calcium into the water, which creates an inexpensive, homemade liquid fertilizer.
Your tap water contains things, like lead, chlorine, and pathogens. These are harmful to your plants and will cause problems when you're consistently watering them with this tap water. Besides these chemicals, the temperature of the water can also play a roll when it comes to plant problems.
Not only does boiling water remove impurities, but it also kills off any pathogens that could harm humans or animals if consumed. So, by boiling already distilled water, you're increasing its purity even more, creating a safe and happy environment for your indoor and outdoor plants to flourish.
Fortunately, most tap water has low levels of chlorine that won't be directly detrimental to your plants. But if you're still concerned, simply check the smell of your tap water. If you can smell chlorine, it likely has unusually high chlorine levels.
Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water to a rolling boil for at least one minute.
To filter tap water for plants, use a fine mesh or activated carbon filter to remove impurities such as heavy metals and chemicals.
If your water really is too hard, dilution as explained for high sodium, will work. An alternative is to use a water softener, but use potassium chloride instead of sodium chloride for recharging the water.
Ice cold water will cause root shock, which may lead to permanent root damage, leaf drop and other problems. Allow the water to warm to room temperature before watering the plants.
All water -- no matter if it comes from a natural spring, artesian well, or regular tap -- may have trace but safe amounts of minerals, bacteria, pesticides, and other contaminants. Distilling rids water of all those impurities. It also removes more than 99.9% of the minerals dissolved in water.
Do not give them tap water or purified drinking water (such as Aquafina or Dasani) or they will quickly turn into mutated carnivorous plants and eat you. (we're just kidding, obviously.) However, your plants will thrive on what is best for them: Pure Spring Water. AIR – here's where the easy part comes in.
