Soil and Water pH Test (25 Tests)
Despatches Within 5-7 days
Pack contains test tube, measuring spoon, pipette, pH liquid, pH powder and detailed instruction book. Enough to perform 25 tests.
pH (acidity /alkalinity) levels control how well plants absorb and utilize nutrients available in the soil.
3 to 7 reading represents acid pH
7 reading represents neutral pH
7 to 10 reading represents alkaline pH
The optimal pH range for most plants is between 5.5 and 7.0. However there are many plants which have adapted to live and thrive at pH values outside this range. It is recommended to test soil pH levels throughout the season but it is especially useful before planting or when the plants are not performing well.
Taking a pH reading: Put a soil sample into the test tube, add pH solution and add barium sulphate, shake and watch the colour develop. Full instruction booklet together with colour chart is provided.
To make the soil more alkaline, for every 1 pH add approx. 300g per square meter of garden lime. To make the soil more acid, for every 1 pH add approx. 70g per square meter of sulphate of ammonia.
Retest for pH level in 30 days. Altering pH does take time, please do not expect too rapid change. Work steadily towards giving the plant the ideal conditions. Always check plant pH requirements.
Garden Tools & Essentials
Seed only orders
P&P on seed only orders is just £2.45.
A single £4.95 P&P charge per order no matter how many items are ordered (to one address - UK only).

For orders containing a mix of seed and non-seed items a combined P&P charge (£7.40 - £2.45 to cover the seed items and £4.95 to cover the cost of non-seed items) will apply. This is due to the vast majority of live products, hardware and seed items being sent out from separate warehouses and the costs involved.
