What is wood ash good for in the garden?
Before we focus on which plants do not like wood ash, and which do, first we need to discuss what are the benefits of using this natural remedy as a whole in your gardens and how to apply it properly. Thanks to wood ash, a lot of plant life can actually flourish. Wood ash is found to contain calcium, potassium, magnesium, phosphorus, and sulphur which are all beneficial for the growth of plants. Some types of wood ash can even contain amounts of iron, zinc, aluminium, and boron, all of which are also valuable for plant sustainably.

How to properly use wood ash?
Did I convince you to use wood ash as a plant stimulant? Great, here is how to do it properly. Firstly, not all types of wood ash will benefit your plants. Choose one that comes from naturally-grown trees. You shouldn’t gather wood ash produced from trees which grow in areas of industrial cites. The soil there can be contaminated with toxic elements which can harm your plants. Also steer clear of ash produced by the burning of waste oil, plastics, treated wood and rubbish. Secondly, when you’ve supplied yourself with the perfect wood ash for your garden, first sift it to remove any large pieces left in it. Make sure you apply the right amount based on the recommendations of a soil fertility test and the needs of your plants. Applying more can do them harm.
Which plants do not like wood ash?
So finally, we have come to the question you’ve all been waiting to be answered. As we said, wood ash can increase the pH of soil, and that’s one of the reasons so many gardeners use it. However, applying it to areas where you are growing plants that love an acidic soil can be harmful to them. The list of such plants is composed of blueberries, strawberries, rhododendrons, camellias, ericas, holly, potatoes, parsley, birch trees, pink oaks and red maples. Using wood ash to promote the growth process of any of these types of plants can actually be detrimental or cause disease.
