For various plants, different types of water are used. Water used for plants might be neutral, acidic, or alkaline. Many plants prefer alkaline water over acidic water. A select few people also choose alkaline water over acidic water.
Not all plants dislike acidic water. The ideal soil for growing plant species including tomatoes, strawberries, and raspberries has a pH between 5.5 and 6.5.
To learn more about why some plants require acidic water to survive, read the article. How does pH of water impact the growth and development of plants? How can acidic water be created for plants? List of plants that thrive in acidic environments.
What is Acidic Water?
Acidity is defined as a pH value that is lower than 7.0.
Acidic water is water that has a pH lower than 7.0. The acidity of the water will increase as the pH drops.

Harmful heavy metals like arsenic, cadmium, sulfur, nickel, chromium, lead, and zinc, among others, may be present in acidic water. Acidic water may, therefore, have negative effects on people, but not on plants in the same way.
Water will have a pH of 4.5 or close to it if the acidity is caused by weak mineral acid.
Due to the presence of certain metals like aluminum and trivalent iron, the water could become acidic. As a result of these metals hydrolyzing in water, water’s acidity is primarily due to them.
Strong mineral acids and weak organic acids can contribute to the acidity of water.
Water acidity may be primarily caused by weak organic acids like tannic and acetic acid as well as strong mineral acids like hydrochloric and sulfuric acid.
However, carbon dioxide, which dissolves in water as carbonic acid and lowers the pH therein, is another significant factor contributing to water’s acidity.
What’s The Best pH of Water For Plants?
Most plants thrive best when the pH of the water is between 5.5 and 7.0, according to the UMass Extension Greenhouse Crops and Floriculture Program (slightly acidic to neutral).
The water will turn alkaline as the pH rises.
There are numerous plants that thrive in more acidic or alkaline water. The fact that acidic water is devoid of chlorine and pollutants is its best feature (Such as water from swimming pools)
Such water also contains minimal to no harmful microorganisms.
However, strong acidic water with a pH of 2.5 to 3.0 works as a natural disinfectant and aids in the death of harmful viruses, molds, and insects that could harm your plants.
To avoid hazardous germs, several experts suggested utilizing such water rather than harmful sprays.
Is Acidic Water Good For Plants?
Yes, plants can thrive in water that is slightly acidic and falls within the pH range of 6.0 to 7.0. For optimum growth, many plants prefer acidic water than alkaline water. This is so that plants can more easily absorb the soluble ionic nutrients that the acid quickly liberates from the soil.
- Use of acidic water aids in the germination process, which is one of its many advantages (the growth of a plant from a spore after a period of dormancy).
- Many organic minerals are broken down by acidic water so that plants can easily dissolve them.
- Water that is acidic and has the right pH balance promotes plant growth.
- Vegetables sprout more quickly in acidic water.
- Seedlings, bulbs, and tubers all grow well and have sturdy root systems.
- Acidic water aids in promoting floral bud development.
- Plants benefit from the acidic water’s quick blossoming and ability to revive wilting plants.
How pH Affects Plants
The plant’s ability to grow is directly impacted by the pH of the water that is being injected into the soil.
Ionic chemical substances that are available in the soil are plant nutrition.
The amount of nutrients and other substances that dissolve in soil water and are thus available to plants depends on the pH of the soil.
The amount of these ionic chemical nutrients that may be absorbed by plants through their roots rises when the pH of the water is lowered.
However, if the pH of the water is too low, too many minerals will dissolve, which could harm the plant.
Because the plant can only absorb a certain amount of minerals at once, when this occurs, the minerals are quickly leached out of the soil and into the drainage.
How does Acidic water Affect Soil And Nutrient Availability
Numerous factors, including soil pH, can influence plant growth.
- The pH range of 5.5 to 7.0 is ideal for the operation of bacteria that transform and release nitrogen from organic matter and certain fertilizers.
- At pH levels below 5.5, plant nutrients drain from the soil significantly more quickly than they do at pH values between 5.5 and 7.0.
- Aluminum can dissolve in some mineral soils at pH values below 5.0, which makes it harmful for plant growth.
- The availability of plant nutrients may also be impacted by soil pH. Plants can best access nutrients in the ideal range of 5.5 to 7.0.
- The soil’s structure can also be impacted by PH, notably in clay soils.
- Clay soils are granular and manageable in their ideal range. However, clay soils will become sticky and challenging to grow if the soil is either very alkaline or acidic.
How to Determine the pH of Soil
Using an Amazon pH meter is an inexpensive and simple approach to determine the pH of soil.
In addition to measuring pH, it also has a moisture meter and a light sensor.
The reasonably priced Trazon Soil 3-in-1 Meter can be used to measure the soil’s pH and moisture content. It checks the pH as well as the amount of moisture and light. Clicking here will take you there!
Using pH test strips is a different, more analytical technique to determine the pH of soil. Depending on whether the soil sample is acidic or alkaline, the test strips’ color will change.
Using Soil Strips to Test pH
- Take a soil sample and use two teaspoons.
- A clean glass should contain the soil.
- Incorporate 1/4 cup of distilled water.
- Stir the soil into the distilled water until it dissolves.
- Through a coffee filter, pour the solution.
- the liquid through a filter into a another, clean container.
- In the liquid, dip the pH test strip.
- Note the outcomes.
When analyzing our soil, we use an efficient and reasonably priced test strip from Amazon. By clicking here, you can access them.
How To Make Acidic Water For Plants?
In fact, most plants prefer acidic water for improved nutrient uptake and growth. However, it’s important to remember that plants prefer slightly acidic water, not severely acidic.
Your plant may suffer because of the overabundance of acids and minerals in highly acidic water.
If we maintain the pH of the water in accordance with the needs of the plants, acidic water can be made safe for use by plants.
Use synthetic magnesium oxide to raise the pH of water to a level that is close to neutral if the acidic water has a pH lower than 6.0. The hardening of water, however, might be brought on by the addition of magnesium oxide.
Say water has a pH of 3 or 4, which is considered to be extremely acidic. If so, adding sodium hydroxide to the water will bring its pH level close to neutral (pH 07), or you can change extremely acidic water into one that is less acidic.
Important Information: To prevent chemical contact with your skin and eyes, you should wear protective goggles and a protective suit.
Attempt to keep sodium hydroxide dry and cool when storing it. Additionally, keep kids away from sodium hydroxide.
In order to lower the pH, you can also add a pH-lowering solution.
In order to properly dissolve and dissociate any solid components you add to a liquid solution, let them soak in the water for a few hours.

Is Alkaline Water Good For Plants?
Alkaline water is defined as water with a pH higher than 7.0.
Alkaline water offers numerous advantages for plant health, hence some plants prefer it to acidic water for quenching their thirst.
- Chlorine can harm plants by causing their leaves to burn. Alkaline water should be used to water the plants to prevent excessive chlorine levels in the water.
- Fluorine levels are likewise decreased by alkaline water. Fluorine prevents photosynthesis, which is extremely harmful to the plant.
- It keeps plants lush and hydrated without allowing them to dry out.
Watering Plants with Acidic Water
In order to avoid inadvertent injury and stress to the plant, you should exercise caution while adding acidic water to your plants.
Top Watering –
When using the top watering technique, water is applied from the top, which may cause acidic water to land on the plant’s leaves.
Depending on how acidic the water is or how long it is allowed to rest on the leaves, acid water may cause the leaves to change color or even die.
Therefore, if you are watering from the top, we advise using a watering can with a long spout so that the water may be directed to the plant’s base without coming in contact with the leaves.
There are numerous watering can options available, but we have found this reasonably priced can that is reliable and efficient in watering plants without making a mess.

Bottom Watering –
Bottom watering is a productive method of watering plants because it enables the soil’s full mass to absorb water.
This is especially helpful when giving plants acidic water.
This is the procedure.
What is Bottom Watering?
By setting the plant in a tray of water that is 1 to 2 inches high, bottom watering is accomplished. Following this, the water is allowed to drain freely, leaving the soil moist and aerated. The water is subsequently absorbed into the soil from the bottom up.
Watering the bottom:
- encourages the formation of strong roots
- prevents gnats and other pests
- minimizes overwatering
- enables the soil to breathe fresh air
Another efficient way to water plants is by misting since it makes the air more humid and enables plants to absorb moisture through their leaves.
However, using acidic water when spraying foliage is not advised since it allows the acidic water to remain on the leaves, which can cause yellowing and withering.
Water plays the same role in a plant’s ability to sustain life as sunlight, temperature, minerals, and nutrients do in all other living things.
Through transpiration and evaporation, water in plants regulates the balance of salts, transports nutrients, and plays a number of other crucial roles in plant physiology.
It is crucial that you utilize the water that your plant prefers as a result. In general, slightly acidic water offers a lot more advantages over alkaline water.
Do plants need alkaline or acidic water?
When we consider the items that people enjoy, we find that they are typically neutral or weakly acidic substances, like water. Additionally, plants favor slightly acidic things. Since it occurs so frequently in nature, some plant experts consider a pH value of roughly 5.5 to be “neutral.”
Is it OK to give plants alkaline water?
For caring for live plants and cut flowers, water ionizer machines produce the ideal alkaline solution. The health of plants is significantly influenced by the pH of the soil. Plants may display other issues in addition to leaf chlorosis and discoloration when the pH level is off.
What is the best pH for watering plants?
from 5.0 to 7.0
Is 7.2 pH water good for plants?
Since most plants do best in the 6.0 to 7.0 (slightly acidic to neutral) pH range, 6.5 is approximately right for most home gardens.
What is the best pH water for plants?
Your growing medium’s pH might be acidic, basic, alkaline, or neutral, but generally speaking, a pH of 5.5 to 6.5 is ideal for plant growth.
