Venus flytraps should only be watered with pure water sources such as distilled water, rainwater, or reverse osmosis water. Using the correct water type is critical to keeping your Venus flytraps alive.
Distilled water is safe for Venus flytraps as it does not contain harmful minerals. It is possible to make distilled water at home in small batches. Also, you can buy distilled water in most grocery stores and water/ice stores. Distilled water is suitable for all carnivorous plants.
In this article, I will teach you how to make distilled water for your plants. Your Venus flytraps will thrive with distilled water, as it is entirely safe for them.
How to Make Distilled Water for Carnivorous Plants
In this section, you will learn how to make distilled water at home. The process is simple, and it only requires a few items that you can find in most kitchens.
To get started you need to collect a few items:
- Large pot with a lid
- Small pot or heatproof (Pyrex) container that fits inside the large pot
- A range
1.- Start by adding water to the large pot and placing it on the kitchen range. Then, grab the small container and place it inside the pot. The small container can float or sink in the large pot, but it should remain upright. Also, try to put the small container in the center of the large pot.
2.- Turn on the range to high and wait until the water starts to boil.
3.- Once the water starts boiling, use the lid to close the large pot. But, instead of placing the cover, as usual, place it upside-down. Finally, add a few blocks of ice on top of the lid.
4.- Collect distilled water: The boiling water will evaporate. The water vapor won’t escape the pot because the pot is closed. Then, the water will condense in the lid (thanks to the ice) and slowly drip into the small container.
The ice will melt, as the process continues, make sure to replace the ice as soon as it runs out.
The water that ends up in the small container is distilled water. The water left outside the small containers has not been purified yet. And, therefore, it is not safe for Venus flytraps.
You can purify any water with this distillation process. You can employ your tap water (regardless of the quality) or bottled water. In both cases, the distilled water you make will be pure (0 ppm – parts per million) and suitable for your carnivorous plants.

Even though making distilled water is not hard, it can be time-consuming. When it makes sense, you can make your own distilled water, but you can also buy it.
In the section below, I have listed several places where you can buy distilled water and their prices.
Where to Buy Distilled Water
Distilled water is available in many different establishments, and it tends to be relatively inexpensive. Generally, you can find them in grocery stores, pharmacies, or water and ice stores.
Grocery stores: Distilled water is sold at most grocery stores. They usually sell it in 1-gallon jugs that cost less than $1. Make sure to select the generic distilled water jug that contains only distilled water.
Pharmacies: Pharmacies also sell distilled water often. Make sure to grab the water jugs that contain pure distilled water. If you are unsure about your choice, I recommend asking the staff. Since distilled water is often used for medical purposes, the staff should be able to point you in the right direction. Also, it should cost less than one to two dollars a gallon.
Water and ice stores: Stores that sell water exclusively tend to carry distilled water at a very affordable price. I buy distilled water for less than 50 cents a gallon. Bring your empty water jug to avoid buying one in store.
If you have a large water jug, you can take home many gallons of distilled water and do not have to worry about buying more in a long time.
Alternate Water Options for Venus Flytraps
Besides distilled water, there are a few options that are also safe for Venus flytraps. Here is a list of some alternatives:
- Reverse osmosis water: RO water is entirely safe for Venus flytraps. However, finding RO water or making it can be challenging. Water stores often carry RO water, but most grocery stores do not.
- Rainwater: If you have access to rainwater, you can use it for your Venus flytraps.
- Filtered water (in some cases): Filtered water is not always safe for Venus flytraps. Some filters remove enough components from the water, while others are not sufficient. Filtered water from a ZeroWater filter is suitable for Venus flytraps as it delivers 0 ppm water. It is the only water filter I have tried that delivers 0 ppm water. Here is a link to check the specs and pricing of a ZeroWater pitcher filter on Amazon. The ZeroWater filter includes a TDS meter and one filter, so you will get your money back if you plan on buying distilled water for your Venus flytraps anyway.
- Tap water (if tested): Depending on the composition and quality of tap water, some might be suitable for Venus flytraps. Water must contain less than 50 ppm (parts per million) to be suitable for Venus flytraps. The ppm reading indicates the number of dissolved solids in the liquid.
Never employ tap water for your Venus flytraps unless you have tested it. You can measure the amount of total dissolved solids in the water with a TDS meter. TDS meters are cheap and easy to use. Here is a link to the one I use; you can check its current price on Amazon.
- Bottled water: Bottled water that contains less than 50 ppm is safe for Venus flytraps. I recently used a TDS meter to measure SmartWater and a generic brand of spring water. SmartWater turned out to have an appropriate ppm level (<30 ppm) for carnivorous plants. The spring water had over 120 ppm, which is too high for Venus flytraps. However, some brands might be suitable.
Venus Flytrap Watering Tips
Making or getting the proper water for Venus flytraps is just the first step. Then, you must water your plant right and consistently to keep it healthy. Here are some tips.
- Water the soil often until the ground is moist but not flooded.
- Never let the soil dry out completely.
- White mold or algae are signs of overwatering.
- Droopy Venus flytraps are a sign of underwatering.
- For Venus flytraps, overwatering is safer than underwatering
- Assess employing a humidifier if you grow your Venus flytraps in an arid environment.
- Adjust the water frequency through the seasons. Venus flytraps tend to consume a lot less water in the winter.
- Consider employing the water tray method (sit your flytrap in water)
- Only water your plant with pure water
- Distilled water, reverse osmosis water, and rainwater is always safe.
- Only employ tap water, filtered water, or bottled water after testing it (<50 ppm).
