STEP BY STEP
Testing your soil
1 COLLECT small soil samples from the part of your garden you wish to test. Bear in mind that the pH may vary slightly across the garden (though seldom extremely).
2 DRY the soil near a radiator or other heat source and remove any stones or debris that could skew the reading. Mix up the soil samples and add to a test tube.
3 POUR the indicator fluid in the quantity suggested – usually up to a line marked on the test tube. This fluid is specially formulated to detect the soil’s acidity or alkalinity.
4 SHAKE the soil and fluid for half a minute, then let the mixture settle to reveal the colour of the fluid. Check this against the chart to find out its pH value.
