Can I use leaves for mulch in the gardens over winter?

Question:

Can you use leaves for mulch in the gardens over winter? After this month’s snow, as I raked again, the undergrowth was green and flourishing.

Answer:

The answer is yes. They’re great for protecting the plants from desiccation, protecting the soil from erosion, and keeping the frost in the ground so plants don’t heave. Some people take the trouble to chop the leaves with their mower before mulching, but unless they’re matted oak leaves, it’s not necessary. The other benefit is that they’re winter cover for pollinators and other invertebrates. Read more in his article.
