Answer: I don't know whether it would be worth your while or not, that depends on what you are spending on hardwood mulch each season, and what you are willing to pay for a mulcher. I can tell you that adding the magnolia leaves to a mulcher and adding that mulch to your plantings is fine. The leaves shouldn't alter the pH one way or another. If I were you, I would start a compost heap. That way, you can add in all of the magnolia leaves, grass clippings, fruit and vegetable peelings, coffee grounds, etc. and have a much richer mulch for your plantings.
