Introduction

Checking the pH level of the soil in potted plants is an essential task for any gardener. The pH level of the soil determines the availability of nutrients for the plant. If the pH level is too high or too low, the plant cannot absorb the nutrients correctly, which results in stunted growth and poor health. Therefore, in this article, we will discuss how to check soil pH in potted plants.

Understanding pH

pH is the measure of the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, where 0 is the most acidic, 7 is neutral, and 14 is the most alkaline. Plants require a specific pH range for optimal growth, which varies depending on the type of plant. For most plants, a pH range between 6.0 and 7.0 is optimal. Acid-loving plants such as azaleas and blueberries require a pH range between 4.5 and 5.5, while alkaline-loving plants such as lavender and sage require a pH range between 7.0 and 8.5.

Tools to check soil pH

There are several ways to check the pH level of the soil in potted plants. One of the easiest and most popular ways is to use a pH testing kit. A pH testing kit comes with a probe or a strip that changes color to indicate the pH level of the soil. Another way is to use a pH meter, which provides an accurate reading of the soil's pH level. A pH meter is a bit more expensive than a testing kit but is more reliable and durable.

Steps to check soil pH using a testing kit

To check the soil pH level using a testing kit, follow these steps:

Collect a sample of soil from the potted plant using a trowel or a spoon.

Put the soil sample in a clean container.

Add distilled water to the soil sample until it becomes a slurry.

Insert the pH testing probe or strip into the soil slurry.

Read the pH level of the soil based on the color indicator on the strip or the digital display on the probe.

Interpreting the results

Once you have determined the pH level of the soil in your potted plant, you need to interpret the results to determine whether the soil is acidic, neutral, or alkaline. If the pH level is below 7.0, the soil is acidic, and you need to add lime to raise the pH level. If the pH level is above 7.0, the soil is alkaline, and you need to add sulfur to lower the pH level. If the pH level is between 6.0 and 7.0, the soil is neutral, and you don't need to make any adjustments.

Conclusion

Checking the pH level of the soil in potted plants is a simple task that can be done using a pH testing kit or a pH meter. By understanding the pH level of the soil, you can provide the necessary nutrients to your plants and ensure their optimal growth and health. Remember to interpret the results and make the necessary adjustments to maintain the pH level in the optimal range for your plant.
