potash from wood ash good for plant bulbs
Steps. 1. Use wood ashes as a soil amendment in the early spring while the soil is dry and before the plant life has begun to actively grow. 1  Nearly all plants benefit from the potash content of wood ashes. 2  Other components of the ashes are beneficial to the soil and plant growth as well. The ashes contain a good amount of lye which is a caustic agent. 2  For this reason, refrain from placing them on young tender plants. 3  Wear gloves when handling the ashes. 4  Use a mask to avoid breathing in the residue and protect your eyes with sunglasses or goggles. 5  Avoid using ashes from cardboard, coal or painted wood.
