Is Alkaline Water Good For Plants?

💥 Yes, alkaline water is good for plants because it will boost the pH of the soil, if it has dropped, however you should know that not all plants will tolerate this water, and you cannot irrigate it for a prolonged time..

Alkaline water has a water pH level of seven or above. Thus, it has a higher water pH level. Plus, it contains more minerals, such as calcium, magnesium, and potassium. But is it beneficial for plants? The uses of alkaline water depend on the type of plant. Some plants will prefer alkaline water with a high pH level.

Others are fond of acidic water with a pH of around 6 to 6.8. But, even for them, you can use alkaline water by adjusting its pH level. For this, you will need acidic pH drops or acid water.

– Plants Tolerating High pH Water

You may be wondering which plant to grow with alkaline soil and water. Thankfully, there are a big number of perennials, trees, and shrubs to grow in alkaline water. For instance, many vines usually thrive in alkaline water, and these would include the Boston Ivy, and the honeysuckle.

On another note, you can also grow ornamental plants and flowers in alkaline soil too. The best options are daisy, hyacinth, geranium, bluebell, and even other such as the lilies. This is a significant key that you would know their tolerance level and how their soil isn’t supposed to be one that is acidic.

Alkaline water helps to neutralize soil that is too acidic, and an acidic soil can be the result of too much fertilizer and as a result the plant would in a dangerous state, however when the water is alkaline, it will help the plant to grow better. This water affects plants that prefer neutral or slightly alkaline soils.

As a result, we often find soil having a pH level below six or five which is highly acidic and harmful to plants. Alkaline water will neutralize this effect and ensure proper growth.

– Prevents Blossom End Rot

Alkaline water can also help to prevent blossom end rot, a common problem in tomatoes and other vegetables. A lack of calcium in the plant causes blossom end rot. Alkaline water can provide an extra boost of calcium. Which means that, calcium will affect plant growth and health too.

– Improves Nutrient Absorption Facility

Alkaline water for plants helps to increase the absorption of nutrients. Alkaline water helps to make nutrients more available to plants.

It can lead to healthier growth. Additionally, alkaline water can help reduce the soil’s acidity, making it more hospitable for plant life.

What Are the Disadvantages of Using Alkaline Water?

The disadvantages of using alkaline water would be making the soil highly basic, and when this happens, it would start to promote growth of different yet harmful bacteria, which would develop in the long run. As a result, your plant would be in a stressful situation.

Alkaline water isn’t always suitable for plants. It has a few harmful setbacks too. You need to consider its disadvantages before pouring it into the soil.

– Promotes Growth of Harmful Bacteria

One thing to remember is that alkaline water can promote the growth of harmful bacteria and fungi. Plus, alkaline water can be harmful to certain types of bacteria. These bacteria are essential for plant health.

You may avoid the problem by using municipal water treated with chlorine. However, you must ask yourself if you would prefer using well water or spring water? Then, consider using filtered or distilled water instead of alkaline water. Because when the bacteria increase, then your plant would start to decay and weaken.

How To Use Alkaline Water For Plants?

To use alkaline water for plants you must first consider the type of plant you will use, and test the water well. In addition, make sure you use filtered water in small amounts in the beginning phase, and remember not to over use the water.

If you’re considering alkaline water for your plants, there are a few things to consider first, and one of them is the type of plants you’re growing. Some plants, like succulents, do better in alkaline soil. Conversely, others prefer acidic conditions. Research the ideal pH level for the plants you’re growing.

For high-level of alkalinity in soil, you may start by hand picking which one of these plants would you see best suited: Campanula, ceanothus, any of the geraniums, the variety of lavender or a choice of dianthus.

– Testing the Water

Test your soil and water before using them on your plants. Is the soil already too alkaline? If so, you must drop the idea of using alkaline water to it. You can buy pH testing strips at most garden stores or test them with litmus paper.

The ideal pH for plant growth is around 6.5 to 7.0. If your water is too alkaline or acidic, it can stunt plant growth or even kill them. Which means that for the sake of their ability to thrive, you should be mindful not to harm the plant.

– Irrigate in Small Amounts

Use filtered alkaline water if possible. This will help remove any impurities that could harm your plants. Plus, you should start with small amounts of alkaline water, so that the plant would not experience a shocking moment when it is being irrigated.

This will give your plants time to adjust to the new pH level and avoid any shock that could damage them.

– Regular Tap Water

Tap water is the most common type of water used for watering plants. It’s easy to access and usually free, making it a budget-friendly option. However, regular tap water can contain chlorine and other chemicals.

If you choose this option, let the water sit for 24 hours before using it on plants. It helps the chemicals to dissipate.
