Potting Soil Test Results
We were unable to use the regular color pH tests on the potting soil as the liquid is very dark even when filtered. We therefore bought a pH (and moisture and light) meter from True Value for $13.29.
The pH meter seems to read 1 pH unit too high (alkaline), after comparing results with the color pH test on a different soil sample. Unless otherwise stated, all pH measurements in this blog will be of actual pH values, not indicated values.
Our potting soil indicated pH6.5, which means the pH is 5.5. We’ll need to add some lime or equivalent. We’ll also add some all-round fertilizer as we can’t measure N/P/K due to the dark color of the liquid.
