Yes, there is absolutely no argument to that. 

Then again, gardeners are at a debate on which type of water is best for hydrating your plants. 

The most controversial question though is….

Is bottled water good for your plants?

Is it really any better than using plain tap water?

How so?

All these questions and more will be answered on this page. Thus, read through the entire article to know the real score once and for all.

What is bottled water?

Bottled waters are drinking waters packaged into food-grade plastic or glass bottles. The water herein is thoroughly processed to achieve and comply with the regulatory health standards. Thus, ensuring it is safe for human consumption

Types of bottled waters?

There are different varieties of bottled waters available in the market today. Here are the most common types and how each differs from one another:

Water Type Treatment Process Description Availability
Distilled  Distillation
  • “Empty water”
  • Chemicals, contaminants, natural minerals, & dissolved solids are being removed
Check the price on Amazon
Purified Filtration, Chlorination, Distillation
  • Similar to distilled water 
  • Certain minerals are being reincorporated back to the liquid (E.g. Calcium chloride, Sodium bicarbonate, & Magnesium sulfate)
Check the price on Amazon
Spring Water Filtration
  • Water is being extracted from an underground source
  • Chlorine is being removed but nitrates, metals, other dissolved solids still remains
Check the price on Amazon
Mineral Water Filtration


  • Similar to spring water with more added minerals
  • Contains dissolved solids including calcium, magnesium, sodium, potassium, bicarbonates, and silica

Which type of bottled water is suitable for plants?

We already know now that bottled waters are not created equal. Some contain more than the others. So, it is quite expected to have different effects when used to water the plants. Which type of bottled water is suitable for plants

There are actually two types that seem to give the most benefit to your plants – purified water and spring water. Both contain traces of inorganic minerals that help your plant to thrive better. 

In the case of spring water, it absorbs the minerals from the soil and the rocks it flows through underground. Thus, making them naturally rich in essential elements. This well includes calcium, magnesium, sodium, and potassium.

Meanwhile, purified water also do contain traces of inorganic minerals. Although it may have initially undergone demineralization processes, certain elements are also added in the later stages. Thus, you can still expect purified water to provide your plants with some level of nutrition.

On the other hand, too many minerals can cause problems too. This is quite true in the case of mineral water. This type of bottled water tends to have greater amounts of inorganic elements. So, using this water to hydrate your plants daily can increase the chances of build-up. Thus, causing it more harm than good in the end.

The distilled water barely contain any nutrients. It is literally stripped off from bacteria to chemicals, and even the good stuff. Thus, this type is the least beneficial for your plant. It can maintain the hydration aspect though. But still, not enough nutrients to allow the plant to flourish.

Is bottled water any better than tap water?

Okay, so we now know that the inorganic minerals from both spring and purified water is what makes it good for your plants. 

But, doesn’t regular tap water also contain them too?

The answer is a definite, YES!

Of course, tap water also contains minerals necessary for plant growth. However, the problem is that certain areas do rather have “hard water”.  That means these sources have higher concentrations of elements including calcium and magnesium. Also, this kind of tap water is most often treated with sodium to help neutralize its hardness.

So, this is actually where the problem with tap water arises.

The accumulation of these calcium, magnesium, and sodium in the soil can then lead to toxicity. Thus, altering the ability of the plant to absorb and retain water and nutrients. In effect, it impairs its cell development and causes growth stunting.

Are there also drawbacks in using bottled water for watering plants?

As always, if there are pros, there are also cons too!

The most obvious drawback in using bottled waters for your plants is COST.

Regardless of the type you use, bottled waters can be costly. Of course, you are not just shelling out for the plain water itself. But, you are actually paying a premium for the treatment processes, packaging, marketing, etcetera. So, keep this on top of your mind if ever you decide to use bottled waters to hydrate your plants.

Another problem with using bottled water is its environmental impact. Almost always, bottled waters are being packaged in plastic or sometimes glass containers. Thus, regular usage of which can add up to our wastes. As we all know, plastic bottles take about a thousand years to decompose. So, just imagine these bottles would still continue to exist in the face of the earth long after you and your plants already dies.

Are there alternatives to bottled waters

Are there alternatives to bottled waters?

Bottled waters are not perfect, nor are they an absolute must for watering your plants. 

Yes, they are good! 

But you should also know that there are alternative means to provide the same benefits without crushing your budget or adding a burden to the environment.

The number one suggestion I can give is to use rainwater. It doesn’t contain hard water elements, it has the right pH for most plants, and it is absolutely FREE! For sure, your plants would feel like they are being nurtured by mother nature itself. All you have to do is to collect as much rainwater as you can whenever the rain pours. Store them securely and that’s it!

However, if you are residing in an area barely experiencing rainfall, then you can just use your regular tap water. There are two ways to ensure the safety of your tap water. You can either use a charcoal filter to help remove the impurities. Or, you can also boil them for a couple of minutes.  Boiling treats tap water by killing the bacteria and other contaminants. Just make sure to allow the boiled water to cool down completely before pouring into your plants.

Wrapping Up:

To answer the main question, is bottled water good for your plants? 

Yes, it is! 

Yes in the sense that it not only hydrates your plants, but it also contains essential minerals to help them thrive at its best. However, you cannot also dismiss the fact that there are some consequences to this too. Using bottled waters to water your plants can be unnecessarily costly. Worse, it even comes with unfavorable environmental repercussions.

As I mentioned earlier, there are always pros and cons. So, learn to weigh which principle you value most. That is the real score!
