...cause the soil to became more acidic?
I've always assumed that the bark around rhodos and azalea roots is not only for keeping moisture longer and weeds from growing, but also to acidify soil there..
Soemone told me it's not so and if this kind of mulch changes pH at all it would be more on alkaline side??
Now I am totally confused..
Does it or does it not changes pH and how?

Kathy , I don't know but it seems to me I have heard the same thing that it tends to make the soil more acid in nature.
Hopefully someone in the know will straighten us out.
And hopefully not Bunny and her .. Theresa

I think there might be a bit of cross purposes here?
I think what you may have heard is that mulches, apart from keeping weeds down and retaining moisture, can take Nitrogen from the ground to aid the rotting down process.
Then as you probably know, nitrogen is required for the leafy parts of a plant, so with evergreens this might not seem to be a good thing.
So it is understandable how confusion can arise.
I have no reason to think that Ph values would change a great deal because of this, if at all.
I hope this helps your peace of mind. It is a big and complicated subject, so if in doubt, buy a soil testing kit and monitor the situation this way.

Thanks, Wanna and Scotia..
So, it does not affect Ph at all, good.
Now the qqq is - does it applies to all kinds of tree bark - for example it doesn't matter, Pine or Cherry tree? same Ph?
(now, THAT probably shows how ignorant I am- there are probably no such mulches)

Q; So, it does not affect Ph at all, good.
I didn't say that I said it is unlikely.
Q; Now the qqq is - does it applies to all kinds of tree bark - for example it doesn't matter, Pine or Cherry tree? same Ph?
A tree is a tree is a tree.
Q ( you didn't ask for) The leaves!!!!now that we are coming to the 'fall'
Keep the leaves for composting in a seperate pile, because they take a long time to rot down.
They are better for a few layers of compost maker. e.g. garrotta or as I use sulphate of ammonia ( its cheaper) and it can be used on the garden (in different doses I must add)
Hope that clarifies the matter!
