To make your tap water safe for your plants, you may need to add a water filtration system to your home that can remove chemicals or find another source of water for your plants.

How do you know if you have chlorinated water in your tap?

The easiest way is to check whether you a have city (municipal) water supply or if you have well water. If you pay for your water, it is most likely from a municipal supply and contains chlorine that is used as a disinfectant.

Well water rarely has chlorine but may contain other contamination, depending on the groundwater in your area.

To be absolutely sure about the content of your tap water, submit samples to a licensed testing lab and study the resulting water report or contact your town offices.

What kind of water is best for plants?

Distilled water is often considered the best water for plants since it is pure water molecules and doesn’t contain any chlorine/chloramines, sodium, fluoride, minerals, heavy metals, or other harmful chemicals.

The issue with distilled water is that you must either purchase it in bottles or invest in an expensive distilling machine of your own.

The other top option is to use a water filter in your home to remove toxic materials present in your tap water.

Is filtered water safe for plants?

Filtered water is perfect for plants since it is far less contaminated compared to unfiltered tap water.

It is recommended to dechlorinate tap water and remove other unwanted contaminants before you feed plants with municipal water.

There are many types of water filters, from simple, charcoal filter pitchers to multi-stage under sink systems, to whole house filtration solutions.

A water filtration system that utilizes a reverse osmosis filter (RO) is the most effective way to remove most contaminants from tap water in the home. They do an excellent job and are very cost-effective.

Reverse osmosis solutions also contain activated charcoal filters that remove excess chlorine that is present in most tap water.

Filtering water makes it safe for everyone in your household, including plants, people, and pets.

A water filter will also remove excess nitrates, phosphates, and lead.

Can I use tap water for plants when I have a water softener?

No, you should not use tap water for plants when you have a water softener.

Water softeners remove beneficial minerals like calcium from the water, which can be harmful to plants. Softened water may have high levels of sodium that your plants don’t need.

If you have hard water and a water softener in your home, it’s best to use filtered or distilled water to water your plants.

Is boiling water the same as distilled water for plants?

No, boiled water is not the same as distilled water for plants.

Boiling water will kill bacteria and any microorganisms that are present in the water, which can be harmful to plants. However, few chemicals are removed when you boil tap water. In fact, after you boil water, any contamination present may be concentrated and less safe for plants.

Distilled water, on the other hand, is free of all harmful chemicals and minerals, making it a much better choice for watering your plants.

Can I use bottled water for my plants?

Yes, you can use some bottled water to water your houseplants. However, it’s important to note that not all bottled water is created equal.

Some brands of bottled water are really just tap water containing the additive chlorine, so be sure to read the label carefully before purchasing a bottle.

Bottled spring water contains natural minerals and nutrients that can be beneficial for most houseplants.

Either way, you may have to purchase a lot of bottled water just for your plants.

Is rain water safe for house plants?

Yes, rainwater is generally safe for house plants.

Rain water doesn’t usually contain any harmful chemicals if it is collected carefully.

Be sure to check the water pH of collected rainwater before using it on sensitive plants.

Proper plant care includes the right amount of sunlight, nutrients, and of course, clean water.

Before you water your plants with tap water, be sure you are not poisoning them with chemicals they don’t need.

Water filters are the best all-around option to make sure your tap water is safe for plants and, as a bonus, safer for your family!

You can find many different types of filters on the market, so do some research to figure out which one would work best for your needs. Once you have a filter, be sure to follow the manufacturer’s instructions for use and maintenance.

With a little effort, you can keep your plants healthy and thriving with nothing but pure H2O straight from the tap!
