Gardening can be a rewarding and enjoyable activity, but it requires some knowledge and preparation. One important aspect to consider before planting is the soil pH. The acidity or alkalinity of your soil has a direct impact on the availability of essential nutrients to your plants. By testing the soil pH, you can ensure proper nutrient uptake and create the optimal conditions for your plants to thrive. In this article, we will explore the importance of soil pH and provide steps on how to test it before planting.

Why is soil pH important?

The pH level of your soil determines its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 considered neutral. Values below 7 indicate acidic soils, while values above 7 indicate alkaline soils. Most plants prefer a slightly acidic to neutral pH range between 6 and 7.5. When the soil pH is outside of this range, certain nutrients become less available to plants, leading to deficiencies and poor growth.

Steps to test soil pH

Testing the soil pH is a simple process that can be done using a soil testing kit, available at most garden centers or through online suppliers. Follow these steps to accurately determine your soil's pH level:

Step 1: Collect soil samples

Start by selecting the area where you intend to plant. Use a clean trowel or shovel to collect soil samples from various spots across the area. For accurate results, make sure to collect samples from at least six different locations within that specific area. Avoid areas where fertilizers or other amendments have been recently applied, as they can affect the pH readings.

Step 2: Prepare the soil samples

Combine all the soil samples collected in a clean container, ensuring it is free from any contaminants. Remove any rocks, roots, or debris that may interfere with the testing process. Break up any clumps and mix the soil thoroughly to obtain a uniform sample.

Step 3: Use a soil testing kit

Follow the instructions provided with your soil testing kit. Typically, you will need to take a small amount of the prepared soil and place it in the testing container. Add the reagent or solution provided in the kit, and mix well. Allow the mixture to sit for the recommended amount of time to allow the color to develop.

Step 4: Determine the pH level

After the waiting period, compare the color of the soil mixture to the color chart provided with your testing kit. The corresponding color will indicate the pH level of your soil. Make a note of the pH value as this will guide you in making soil amendments if necessary.

Interpreting the results

Now that you have determined the pH level of your soil, it’s essential to understand the implications of the results:

  • pH below 6: Acidic soil
  • pH above 7.5: Alkaline soil
  • pH between 6 and 7.5: Optimal range

If your soil pH falls outside the optimal range, there are several ways to make adjustments and create a more suitable environment for your plants:

Add lime for acidic soil

If your soil is too acidic, adding lime can help raise its pH level. Lime is commonly available at garden centers and can be applied according to the recommended dosage. It's essential to follow the instructions carefully and retest the soil after applying lime to ensure the desired pH level is reached.

Use elemental sulfur for alkaline soil

For alkaline soil, elemental sulfur can be used to lower the pH level. Like lime, elemental sulfur is readily available at garden centers and should be applied according to the instructions provided. It is important to note that adjusting soil pH takes time, so be patient and retest periodically to monitor the progress.

The benefits of proper soil pH

By testing and adjusting the soil pH before planting, you provide your plants with the best possible growing conditions. Proper pH levels promote nutrient availability, which is vital for healthy growth, vibrant foliage, and abundant blooms. It also helps in maintaining the soil structure, benefiting beneficial microorganisms and earthworms that contribute to soil fertility.

Remember, different plants have varying pH preferences, so it's essential to research the specific needs of the plants you are planning to grow. Some plants, such as blueberries, azaleas, or rhododendrons, thrive in acidic soil, while others may require a more alkaline environment. By understanding your plants' preferences and adjusting the soil pH accordingly, you can create an optimal environment for their growth and maximize your gardening success.


Ensuring the right pH level in your garden soil is crucial for supplying plants with the necessary nutrients for healthy growth. By testing the soil pH before planting, you can identify any imbalances and take corrective measures to create an optimal growing environment. Remember to follow the steps outlined in this article and make necessary soil amendments based on the test results. With proper pH levels, your plants will have improved nutrient uptake, resulting in stronger, healthier, and more productive plants.
