Working smarter not harder...lol. Ma Nature mulched my collards and kale for me. It was actually pretty awesome. One day last week I was lamenting that I would have to come home and rake all my leaves. Then we had a pretty epic windstorm that blew the whole yard clean and piled them up right where I would have raked them. Made the fall clean-up very easy this year. My collards and kale were well established and "caught" just enough of the leaves to give themselves a good mulching.
