Wood Ash

Use sparingly as wood ash does increase PH level of the soil.

When using in soil where potatoes, berries or other acidity loving plants are grown, be sure to add acidity rich fertilizer such as coffee grounds.




Wood ash is a useful fertilizer and amendment that can be used in the garden, on lawns, and in landscapes, too. It is a good source of several important minerals and nutrients for your yard and garden. It is also a highly effective amendment for modifying soil pH.

The most abundant mineral nutrient in wood ash is calcium. On average, the calcium content of wood ash is 20% or higher. Calcium is an important element that helps plants stave off diseases such as the notorious blossom end rot.

Wood ash is also a very good source of potassium—it is about 5% potassium. It is commonly known or referred to as “potash” for this reason, and potassium is the mineral that wood ash is most often used for. When people look for a source of potassium, they look to potash—wood ashes.

Wood ash is also useful for pest control. The salt in the wood ash will kill bothersome pests like snails, slugs and some kinds of soft bodied invertebrates. To use wood ash for pest control, simply sprinkle it around the base of plants being attacked by soft bodied pests. If the ash gets wet, you’ll need to refresh the wood ashes as the water will leach away the salt that makes wood ashes an effective pest control.
