Houseplants can add life and greenery to any indoor space. However, keeping houseplants healthy requires meeting their basic needs, including providing the right type of water. Some plant owners swear by using distilled water, believing it’s best for their plants. But is distilled water truly necessary for houseplants to thrive? Let’s take a closer look.

What is Distilled Water?

Distilled water is water that has been purified through a process called distillation. This involves boiling water and condensing the steam to remove impurities, minerals, and salts.

The result is water in its purest possible form – just hydrogen and oxygen molecules. Distilled water contains no dissolved solids, minerals, or contaminants that are typically found in tap water or natural sources like lakes and rivers.

Some key things to know about distilled water:

It has a neutral pH of around 7.
It does not contain minerals like calcium, magnesium, and iron that plants need.
It lacks chlorine and fluoride that are added to tap water.
Its purity means it is sterile with no microorganisms.
It has a flat, bland taste due to the removal of minerals.

Distilled water can be purchased in stores, or you can distill your own at home with a simple distilling apparatus. While it has medical and scientific uses, the main reason houseplant owners use it is to avoid the buildup of mineral deposits on the plants and soil over time.

Do Houseplants Really Need Distilled Water?

Many houseplant care guides recommend using distilled water or rainwater for houseplants, stating that the minerals and salts in tap water can accumulate in the soil and damage plant roots. However, this advice is often overstated.

The truth is that most common houseplants do not require distilled water and will grow just fine with good quality tap water or filtered water.

Here are some key reasons why distilled water is not necessary for most houseplants:

Tap and Filtered Water Contain Beneficial Minerals

Tap water contains essential minerals like calcium, magnesium, iron, and manganese that plants need for healthy growth. These minerals are naturally present in soil as well.

While it’s true that minerals can build up over time, this generally takes many years to happen in indoor houseplants that are watered moderately.

Filtered water removes chlorine and fluoride while retaining helpful minerals, making it a good middle ground.

Many Houseplants Tolerate Minerals

Research shows that common houseplants like pothos, philodendrons, spider plants, dracaenas, and peace lilies can tolerate the mineral content in tap water. They show no significant differences in growth between distilled and tap water.

Tropical plants adapted to rainy environments are used to receiving water with some dissolved minerals and nutrients. They have mechanisms to process and absorb them.

Distilled Water Lacks Beneficial Nutrients

Since distilled water is devoid of any minerals, it does not provide nutrients that plants need. Exclusive use of distilled water over many years can lead to mineral deficiencies in plants.

Adding liquid fertilizer provides necessary nutrients, but tap or filtered water already contains small amounts of helpful minerals on its own.

Buildup Takes Time in Houseplant Environments

Buildup of mineral deposits from tap water happens very slowly in indoor houseplants compared to outdoor gardens.

With moderate watering, it could take many years before buildup begins affecting plant health. Leaching the soil annually by heavy watering can remove any accumulated salts.

It’s an Added Expense and Hassle

Having to purchase distilled water or distill it yourself adds cost and effort compared to readily available tap or filtered water. For houseplant owners with a large collection, this can become quite inconvenient.

When to Use Distilled Water for Houseplants

While distilled water is unnecessary for most common houseplants, there are some situations where it can be beneficial:

For Sensitive Plant Species

Some specialized plant species are more sensitive to minerals and prefer very pure, soft water. These include:

Carnivorous plants like Venus flytraps and pitcher plants.
Tropical orchids, bromeliads, anthuriums.
African violets.
Begonias.

Refer to specific care guidelines, as even among these there are differences. Orchids, for example, need some mineral content.

For Seed Germination

Use distilled water when sprouting seeds for propagation. Pure water prevents mineral buildup as delicate new roots form. Once seeds sprout, tap water is fine.

For Cuttings and Propagation

Taking cuttings from plants to propagate in water is more successful with distilled water. The purity prevents microorganisms from causing rot and allows better root formation.

For New Houseplants

Watering new houseplants with distilled water for the first few months gives them a fresh start in new soil, especially if they arrive with mineral deposits.

For Hard Water Areas

If tap water in your area is extremely hard with high mineral content, consider mixing half distilled and half tap water for houseplants. Or use distilled water monthly to flush soil.

For Water-Sensitive Plants

Some plants like maidenhair ferns, calatheas, and marantas have leaves prone to browning if tap water touches them. Use distilled water to mist them.

Tips for Using Distilled Water

If you choose to use distilled water for your indoor plants, keep these tips in mind:

Mix it half and half with tap water to provide some essential minerals.
Add liquid fertilizer or compost tea to provide nutrients.
Flush the soil monthly with distilled water to prevent buildup.
Allow distilled water to come to room temperature before watering.
Consider using distilled water for plants prone to crispy leaf edges.
Test your tap water’s mineral content before deciding if distilled water is needed.
Adjust slowly if switching plants from tap to distilled water.
Use distilled water for propagating cuttings then switch to tap.

Frequently Asked Questions

Is it okay to use distilled water all the time on my houseplants?

Exclusively using distilled water long-term can lead to mineral deficiencies over many years as it lacks essential nutrients plants need. It’s better to use distilled water periodically or mix half with tap water.

Can I use distilled water for my vegetable garden?

Distilled water is not recommended for vegetable gardens as plants need the minerals present in tap water. The continual mineral leaching can make soil unhealthy.

Is dehumidifier water the same as distilled water?

Dehumidifier water is essentially distilled water as the condensation process removes minerals. However, check the user manual as some models add back minerals before collection.

Does distilled water keep plants from growing?

Distilled water itself does not limit plant growth, but lacking essential mineral nutrients long-term can stunt plants. Use occasionally mixed with fertilizer, or alternate with tap water for a balance.

Is it safe for pets to drink distilled water?

Distilled water is not recommended as the sole water source for pets as it lacks minerals. It can be given occasionally, but regular tap or filtered water is best. Check with your veterinarian.

Can I use distilled water in my steam iron?

Yes, distilled water is recommended for steam irons to prevent mineral buildup. The purity helps the iron glide smoothly and extends the steam vent life. Empty after use.

Conclusion

To summarize, distilled water is not necessary for the majority of common houseplants. Tap or filtered water provides the essential minerals plants need for healthy growth in indoor environments. However, distilled water can be beneficial for sensitive plant species, during propagation, and for an occasional mineral flush. Rather than being a strict requirement, distilled water is just one tool that can be used judiciously as part of good houseplant care. Focus more on providing the right lighting, soil, fertilizer, humidity, and temperature for your plants to truly thrive.

Is It Actually Necessary to Use Distilled Water for Houseplants?

Houseplants are a great way to decorate your home and purify the air. However, keeping houseplants alive and thriving requires meeting their needs. One of the most common questions is whether it’s necessary to use distilled water. Here’s a detailed look at the issue to help you decide if you need distilled water for your houseplants.

Is It Actually Necessary to Use Distilled Water for Houseplants?

Having vibrant, healthy houseplants can make any home feel more alive. However, keeping houseplants thriving requires meeting their water needs. Some experts insist that distilled water is essential for indoor plants to prevent mineral buildup. In this article, we’ll examine if it’s actually necessary to use distilled water for houseplants or if regular tap water will suffice.

What is Distilled Water?

Distilled water is water that has undergone a purification process known as distillation. This involves:

Boiling water into steam
Condensing the steam so impurities and minerals are left behind
Collecting the pure condensed vapor as distilled water

The resulting distilled water contains:

Only hydrogen and oxygen molecules
No dissolved solids, minerals or contaminants
Neutral pH around 7
No chlorine, fluoride, calcium, magnesium, etc.

Some key properties of distilled water:

Sterile and microorganism-free
Lacking in taste due to removed minerals
Available for purchase or can be home distilled
Used to avoid mineral buildup on plants over time

Do Indoor Plants Really Need Distilled Water?

Many indoor plant guides suggest watering houseplants with distilled or rainwater to prevent tap water minerals damaging plant roots. However, most common houseplants actually grow well using regular tap water. Here’s why:

Tap Water Contains Essential Minerals

Tap water contains calcium, magnesium and other beneficial minerals plants need to grow healthy and strong. These same minerals are naturally present in potting soil.

While minerals can accumulate over many years, this buildup happens slowly with moderate indoor watering. Filtered water removes chlorine and fluoride while retaining helpful minerals.

Houseplants Are Adapted to Tolerate Minerals

Studies show that pothos, philodendrons, dracaenas and other common houseplants can tolerate the level of dissolved minerals and salts typically found in tap water.

As tropical plants, they have adapted to absorb and process minerals and nutrients from rainwater.

Distilled Water Lacks Nutrients

Distilled water’s purity means it contains no minerals or nutrients. Relying solely on distilled water long-term can lead to deficiencies without added fertilizer.

Tap water actually contains small amounts of helpful nutrients plants can use.

Slow Buildup in Indoor Conditions

Mineral deposits from tap water build up far more slowly for indoor houseplants compared to outdoor gardens.

With routine, moderate watering, it could take many years before buildup impacts plant health. Soil can be flushed annually to remove any accumulated salts.

Added Cost and Effort

Having to buy distilled water or distill your own adds cost and effort compared to easily available tap water. This can become burdensome, especially when caring for many plants.

When to Use Distilled Water for Houseplants

While not mandatory for most common houseplants, distilled water can be beneficial in certain situations:

Sensitive Plant Varieties

Some plants like orchids, bromeliads, Venus flytraps and begonias prefer pure, mineral-free water. Refer to specific care requirements.

Seed Germination

Use distilled water when sprouting seeds to prevent mineral buildup while delicate new roots are forming.

Rooting Cuttings

Distilled water prevents rot and encourages better root growth when rooting cuttings in water.
