No, it’s not necessary to remove all the leaves from your lawn—in fact, leaving some behind can be beneficial. While it's important to clear thick layers of leaves that can smother your grass, leaving a light scattering of leaves can help feed your soil while also providing safe winter habitat for pollinators like bumble bees. Leftover leaves will eventually break down, enriching the soil and promoting healthy lawn growth.

In most cases, it’s better to remove rocks before adding mulch. Layering the two will restrict drainage and plant health, and can create an unpleasant texture underfoot.

If you don’t have too many fallen leaves, one option is to leave them in place. They’ll eventually decompose, adding vital nutrients to the soil. But if you have a thick layer of leaves smothering your lawn, you’ll want to either mulch them or bag them up for removal. If you choose to collect and bag your leaves, check with your local municipality on any specific guidelines to dispose of them. Many cities offer curbside pickup if the leaves are disposed of in yard waste bags or containers. 

Yes, you can absolutely make your own mulch, and there are a few ways to go about it. First, you can lay down pine needles or mulched leaves if you’re mulching in the fall. In the spring and summer, you can use mulched grass clippings. Alternatively, you can lay down a few layers of newspaper in your garden and gently wet the paper to keep it in place.
