How to Change Potted Plant Soil pH Level

Potted plants are great additions to any living space, but their health and growth largely depend on the soil pH level in the pots. Incorrect pH levels can lead to yellowing of leaves, stunted growth, and eventual death of the plant. Therefore, it is important to know how to change the soil pH level to ensure your potted plants thrive.

Testing the Soil pH

Before you can change the soil pH level, you need to know the current pH levels of your potted plant soils. You can easily test the soil pH level using a pH test kit available at any plant or garden store. Take a sample of the soil from the pot and follow the instructions on the test kit to determine the pH level. A pH level of 7 is neutral, and any number less than 7 indicates acidity while any number greater than 7 indicates alkalinity.

Raising Soil pH Levels

If the soil pH level is too low, meaning it is acidic, you can raise it by adding limestone or crushed eggshells to the soil. These materials react with the soil, releasing calcium ions that neutralize the acidity in the soil. You can also add wood ash to the soil for the same effect. However, be careful when adding wood ash as it can make the soil too alkaline if used in excess.

Lowering Soil pH Levels

If the soil pH level is too high, meaning it is alkaline, you can lower it by adding organic matter to the soil. This can include peat moss, pine needles, or sulfur. Peat moss and pine needles help to acidify the soil, while sulfur reacts with the soil to make it more acidic. However, be cautious when adding sulfur to the soil as overapplication can make the soil too acidic, which may harm the plant's roots.

Maintaining Soil pH Levels

Once you have adjusted the soil pH level, it is important to maintain it to ensure the plant's continued health and growth. Regularly test the soil pH level to ensure that it remains within the desired range for the plant. It is also important to water your plants with pH-neutral water, as the pH level of the water can also affect the soil pH level. Lastly, ensure that the plant pot is not sitting in water, as excess water can make the soil too alkaline.

Conclusion

Changing the pH level of potted plant soil is a simple process that can greatly improve the health and growth of your plants. By testing the soil pH, adding materials to increase or decrease pH levels, and maintaining pH levels, you can create the ideal growing conditions for your potted plants, ensuring they thrive and continue to bring beauty to your space.
