Are leaves too acidic to mow into a lawn?
Bob in Fairfax writes: “My lawn is cut at the highest setting the mower will allow (based on your advice) and I mulch the grass clippings back into the lawn (also per your advice,) and the lawn looks great. My question: Are the vast amounts of leaves collecting on my lawn too acidic to also mulch into the grass? (I’ve heard that they are.) Should I just rake or vac them up and bag them?”
Not if you’re going to put those precious leaves out at the curb, Bob. I would support your collecting them if you’re going to shred them up for mulch or compost making. But if you’re going to otherwise (gasp!) dispose of them, do mow them into the lawn
