Gardman Combination pH & Moisture Meter

This dual function Combination pH and Moisture Meter measures the pH as well as moisture levels in soil. It provides the vital information required to custom treat soil to the crop.

• Analogue dial so no batteries required
• Easy to use – instructions and optimum pH level guide included

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
