Gardman Combination pH & Moisture Meter

Taking a pH Reading

Some plants require a particular soil pH in order to grow and thrive

To help choose the right plants for your garden use the Combination pH & Moisture Meter to check the pH of your garden soil
Preparing the Soil

Remove stones, leaves and twigs from the surface of the soil

Loosen the soil with a trowel to a depth of 10 – 15cm
Wet the soil with water (preferably rainwater) to a muddy consistency
Lightly clean the pH probe but not the tip using an abrasive material/scourer (not included)
Wipe away any powdery deposits with a paper tissue
Push the probe vertically into the soil to a depth of 10 – 15cm
Take a reading after 60 seconds
Remove, clean and prepare probe as previously described. Repeat above by inserting the probe into a different but adjacent point to check the first reading
Interpreting the pH Reading
pH 3-6 Acidic
pH 7 Neutral
pH 8-10 Alkaline
To reduce acidity apply 300g/m² of ground limestone for every 1 pH increase required
To increase acidity apply 70g/m² of sulphate of ammonia
Checking Moisture Content

Houseplants and outdoor plants grown in hanging baskets and containers need the right amount of water to produce the best results

Use the Combination pH & Moisture Meter to prevent over or under watering by checking the moisture content of the soil or compost before watering your plants
Taking a Moisture Reading
Push the probe vertically into the compost mid-way between the plant and the edge of the pot. A reading can be taken immediately
Interpreting the Reading
Red zone = Dry. Suits Cacti and Sansevieria
Green zone = Damp. Suits most plants
Blue zone = Wet. Suits aquatic plants
Taking Care of the Combination pH & Moisture Meter

Remove the probe from the soil or compost after taking a reading

Always wipe the probe clean after use
