It’s important to choose a representative soil sample for testing. Avoid areas that have recently been treated with fertiliser, compost or other materials, as these can affect the reading. Soil pH can vary widely across a garden, so it’s best to test samples from several areas to get an accurate picture.
Remove any stones and twigs from your sample and place the required amount in the tube. Add the chemical solution, shake the contents, and wait until the soil particles settle. Once the liquid clears, compare it against the chart - its colour indicates the pH.
Use the results of this test when choosing which plants to grow in your garden. It will save you the disappointment and wasted effort - not to mention wasted money - of trying to grow plants that will never thrive in your soil.
You can find out which plants thrive in acid or alkaline soil by going to our 'Plants' section. In the 'Plant search' facility you can select the appropriate soil type and you will get a list of detailed profiles on a wide range of plants that will enjoy your selected soil conditions.
