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.

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.
