Dechlorinate water for plants is the task that you would do to save your plants from many issues. Chlorine is an element that can have adverse effects on your plants, from turning their leaves brown to actually killing them off.Dechlorinate Water for Plants

Many farmers and gardeners find it surprising that their plants have excellent access to fertilizer, water, and light but still show the aforementioned symptoms without knowing that chlorine buildup is the cause.

Don’t worry, because the steps below will show you the different ways to make tap water safe for your house plants.

What Is the Most Efficient Way to Dechlorinate Water For Plants?

The most efficient way to dechlorinate water for plants is to use dechlorinating tablets, and boil the water. You can also allow the water to evaporate naturally, or filter the water. Lastly, you can aim to have a water aeration process to help eliminate levels of chlorine.

– Using Dechlorinating Tablets

Dechlorinating tablets are used to eliminate chlorine found in tap water. Besides being an excellent method to dechlorinate tap water for plant growth, these tablets are also great for water used in fish tanks and aquariums.Using Dechlorinating Water Tablets

For this to work in an efficient way, you must fill any container with the water you want to use on your plants and get your dechlorination tablets for plants. After doing so, try to check the label or tablet packaging for instructions on the right dose to use.

Just as you have selected the right dosage, crush the tablets into powder form, so now you may use the whole tablet, depending on the instructions on the label or packaging. Add the tablet to the water in your container and stir it properly until the tablet dissolves fully.

The wait time should also be included on the packaging or label of the product you purchase. Also, keep in mind that the wait time will change depending on the number of tablets used, but just as the wait time is over, use the water that is now lacking in chlorine on your plants.

– Boiling the Chlorinated Water

Boiling your water before watering plants with it is another good way to eliminate chlorine from the water. When you boil the water, it aerates and produces heat, which helps remove chlorine after about 20 minutes. Note that this method may not be practical if you have a big farm or garden.

But if your garden is a small one, you may want to start by filling your pot or kettle with water, light your stove and bring the water to a boil. On average, the water boils for about 20 minutes or more. Once the period is up, let the water cool and reach room temperature so that it wouldn’t cause any hazards on the way, and then water your plants with cool, distilled water.

– Using a Filter

Filtering your water is another effective way to eliminate chlorine. Unlike the boiling option, this method is great for those with huge gardens or farms. With a filter system, you’ll be able to significantly minimize the chlorine in your tap water, if not eliminate it.

To begin first, install the reverse osmosis, or RO filter by attaching it to your water supply and the kitchen sink, so your water has to pass through the filter. Then, use your manufacturer’s guide to determine how to install your filter, and since there’s no one-size-fits-all method to fix different products, using the manufacturer’s instructions is ideal.Using Filter to Dechlorinate Water

Once the filter has been fixed, turn on the water supply the filter is attached to and allow it to run for the right amount of time. Be detailed on this, because doing so will help flush out any impurities, including chlorine, so turn off the water source and remove the filter housing.

Find and locate the carbon filter cartridge that’s responsible for taking out the chlorine. The cartridge is typically located in the filter housing, and it’s often designed with a cylindrical shape, so you must remove the cartridge and replace it with a different one specifically designed to eliminate chlorine.

Return the filter housing to its right spot, run the water supply again, and wait until the filtering process is complete. Although do keep in mind how the filtering or RO process can take up to 30 to 45 minutes, depending on the filter’s type and size and the amount of water being treated. Once the filtering process has been completed, use the filtered water on your plants.

– Natural Evaporation

If you’re looking for a free method you can use to eliminate chlorine from your plant water, natural evaporation is the ideal option for you. However, the process can be slow, costing you your time.Dechlorinate Water by Evaporation

To perform the following task in the right way, you must begin to get a container, such as a bucket, and fill it halfway with tap water. Then, leave the water overnight, and the chlorine should dissipate on its own, depending on the amount of water you’re trying to purify.

Taking two ppm of chlorine out of 10 gallons of filtered tap water via the natural evaporation method can take approximately 110 hours or four days and a half. However, you must ensure that the tap water sits for at least 24 hours to get rid of the chlorine content, effectively.

This matter would be depending on the volume of water and the quantity of chlorine in the water, you may need to wait up to five days or more before being able to water your plants.

Keep in mind that aeration, water movement, and ultraviolet radiation can help decrease the time needed for the evaporation process. Just after, you should go ahead and water plants with the evaporated water once enough time has elapsed.

– Water Aeration

Aerating your water can also help in removing chlorine from the water. You can aerate your plant water by using air pumps. While this method requires a bit of effort, there’s no denying its effectiveness.Aerating Water to Dechlorinate

You can begin to dechlorinate water with air pumps by choosing the right air pump and air stone that’s ideal for the container you want to put your water in. The pump you choose will also depend on the volume of water you want to aerate. So now, fix the air stone to the air pump via airline tubing, ensure the tubing fits tightly, and place the air stone at the bottom of your water container.

If the pot of the plant is large, you may need to utilize multiple air stones to be precise to get adequate aeration, so connect the air pump to an electric source. Turn on the air pump and adjust its settings to make sure the right amount of air is being passed into the water.

The air stone should start creating bubbles in the water, which in turn should help you remove or minimize the chlorine in your water. For this, you can add dechlorinating tablets for more effectiveness, but the aeration process will be done in about 30 to 45 minutes.


If you can’t utilize any of the options above, you can opt for bottled water, plus it can be purchased online if you’re looking for where to buy dechlorinated water. Make sure to note down these tips when dechlorinating your water to make your plants grow properly:

  • Dechlorinating tablets, boiling your water, and using water filters are the most effective methods you can utilize.
  • While too much chlorine can damage your plant and cause the leaves to look burnt, too little chlorine can cause your plant’s leaves to become yellow.
  • Supplementing the water aeration method with dechlorinating tablets can help you improve its effectiveness.
  • You may need to leave your water to stay for a long time if you’re using the natural evaporation method.
  • If you use the boiling method, make sure you wait until your water cools down to room temperature right before using it to water your plants.

Ironically, chlorine is an essential element for plants as it helps with their photosynthesis process, but too much of it will damage the plant, so now you will have healthier plants.
