Combination pH and 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
