I have a queston. I can get a lot of acacia wood chips for mulching the soil. Now I heard someone say that the acacia trees and also the wood chips will acidificate the soil. Does anyone know more about this or has experience with this?
I wouldn’t hesitate to use them. Even if they did acidify somewhat, the benefits of soil protection, water conservation and weed suppression as well as adding organic matter as they breakdown far out way any disadvantage.
By no means an expert but would suggest follow your nose, any tree with a strong sharp smell is likely to have an effect, eucalyptus, juniper, and many pine tree’s I know kill off competition in this way.
Thanks a lot.
In the meantime I heard also when some trees are allelopatic, you can always let the chips lie in a heap and the fungi will do their work. At the moment that there are white streaks in the heap, it seems all allelopatic parts are gone.
