Introduction

Soil pH level is a crucial factor for growing healthy plants in your garden. If the pH level of your soil is too acidic (below 6.0) or too alkaline (above 7.5), plants may struggle to grow or even die. In this article, we will discuss how to raise pH of soil in potted plants and achieve optimal growing conditions.

Test your soil pH

The first step to raising the soil pH level in your potted plants is to test it. Use a pH test kit, available at most garden centers, to check the acidity or alkalinity of your soil. Follow the instructions provided with the kit to get accurate results. Once you know the pH level of your soil, you can take the necessary steps to raise it to the desired level.

Add lime

If your soil pH level is too acidic, you can raise it by adding lime. Dolomitic lime and garden lime are commonly used to raise soil pH. Garden lime is fast-acting and effective, while dolomitic lime contains magnesium, which can also help with the growth of plants. Sprinkle the lime evenly over the soil surface and mix it in with a shovel. Be sure to wear gloves and a mask when handling lime, as it can cause skin and respiratory irritation.

Add wood ash

If you don't have lime available, you can also raise the pH of your soil by adding wood ash. Wood ash is a natural source of potassium and calcium, which can help neutralize acidic soil. Sprinkle a thin layer of wood ash over the soil surface and mix it in with a rake or shovel. Be careful not to add too much, as excess ash can raise soil pH too much and harm plants.

Add crushed oyster shells

Another natural way to raise pH level in soil is by adding crushed oyster shells. Oyster shells are rich in calcium carbonate, which can help neutralize acidic soils. Crushed shells should be spread evenly over the soil surface and mixed in with a rake or shovel. Keep in mind that this method may take longer than using lime or wood ash to raise the pH level of your soil.

Use a pH adjuster

If the pH level of your soil is too alkaline, you can lower it by adding a pH adjuster. These products are available at most garden centers and come in either liquid or granular form. Follow the instructions provided with the product to ensure that you add the correct amount for your soil type and pH level.

Conclusion

Raising the pH level of your soil in potted plants is essential to achieve optimal growing conditions for your plants. Testing your soil, using natural sources like lime, wood ash, and crushed oyster shells, or using a pH adjuster can all help you achieve the desired pH level for your plants to thrive. Remember to wear gloves and a mask when handling lime and to avoid adding too much wood ash or crushed shells to prevent over acidification in your soil.
