    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?

    Greetings,
    Maria

    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.

    I second that, if you are worried about the pH getting too low, you could always sprinkle a little bit of lime on the chips to balance it out, but wait and see what happens if you do nothing first.

    Are there any trees that one should avoid for use of wood chips? Eucalyptus I have heard is not worth using. Any other trees one should avoid?

    thanks, new to this site today and love it.

    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.

    Did find this though thought it might help

    offers some comparisons and right down the bottom they give a simple method for testing yourself 🙂

    In permaculture, “the problem is the solution”. Do you have plants you want to control or eliminate? Use that mulch for that. Otherwise just use it lightly with other mulches and it will balance out.

    Thank you Sheesh. I’ll take a look at the article.

    Dear David, Yes, that is a good thought.

    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.

    Thanks Maria. That makes since. Do you happen to have a link to this information?

    Acacia’s are nitrogen fixers and pioneers in the forest so they should make great mulch. I’ve used Eucalyptus mulch with great success around my fruit trees, it turns into wonderful loam by the end of the year, this has also been true of cypress chips and all the other weird mixes we have got from the guys who clear vegetation under power lines. I have found even pine needles have worked wonders. You can always add a bit of chook poo or something with a higher ph if the soil becomes acid but I haven’t found it to be a problem. Soil loves organic matter. of course it would all depend on what you are using the mulch for.

    Thank you Kristy! We have a big Acacia tree near our CSA gardens. The tree litter is amazing for mulch. I love hearing about personal experience. What is chook poo?
    Blessings on your journey.
