What is 'mulch'?

Tracy DiSabato-Aust (Garden Designer and Author) gives expert video advice on: What is 'mulch'?; What type of mulch should I use in my garden?; What is the proper method of mulching?

Mulch can be a variety of different items. It can be pine needles which I love to use. It can be a pine soil conditioner, which I also use, which is a high organic conditioner. We can use cocoa shells, and what we use it for is basically to retain moisture to help prevent weed, seed germination and we also use it to prevent soil temperature fluctuation.
