Hardwood ashes dissolve readily, acting on the soil pH level. Sixty-eight pounds of wood ashes applied to 1,000 square feet of area raises the pH one-tenth of a point, such as 6.0 to 6.1. Use 33 percent less wood ash in sandy soil and 15 percent more in heavy clay soil.he addition of wood ashes can balance soil pH and supply calcium, required by bulbs for healthy foliage and strong stems. Potassium, a nutrient quickly depleted by irises, is also supplied by wood ashes, which can protect plants from becoming weak and subject to disease.
