QR Code Link to This Post
Once you have received the results of your soil test, if the recommendation is to add lime to raise the pH, the general rule is it takes 2 pounds of wood ash to equal the neutralizing power of 1 pound of ground limestone. For example if the lime recommendation is to add 8 pounds of lime per 100 square feet, 16 pounds of wood ash would be the equivalent.
Wood ashes should NOT be placed around certain plants; for example, blueberries that prefer more acidic soils, or potatoes, as scab disease becomes more prevalent in soils with a high pH. Potatoes are less likely to develop scab when the pH is between 5.0 and 5.2. See pics
