LEAVES, leaves, leaves. I'm going to try something called a "compost sandwich" using some of the billions of leaves that have fallen in the past few weeks.

If you're building new garden beds, or just enriching the old ones, make compost sandwiches on top of them now. Also called sheet composting, or lasagna gardening, it's simple and makes wonderful, loamy soil. The key is to alternate between "greens" (nitrogen-based plant material such as fruit and vegetable scraps, grass clippings, coffee grounds, tea bags, and perennial plant clippings) and "browns" (carbon-based plant material, such as leaves, twigs, wood chips, straw, shredded newsprint and cardboard).

Start by covering the area you want to make into a bed with cardboard - a great way to recycle those old corrugated boxes. Next, add a 2-inch layer of newspaper. Water each layer to speed up the decomposition process. After the newspaper, add "greens." If it's grass, keep it thin. Again, don't forget to water lightly between layers.

A layer of manure comes next, then a thin coating of topsoil. These can be purchased in bags at any garden center.  Next, "browns." Try to use something other than newspaper, but it can be used if you have no leaves or other materials.

Now, for the good part. Leave it alone! (The only work you might have to do is to add a bit of water, if it's a dry winter.)  Let the sandwich sit throughout the cold months- the method works best when you just let them alone for several months. Voila! Instant garden beds.

  • Myth: Compost smells bad.
  • Reality: Not if you're making it right. The secret to keeping the stink out is creating a balance between your "browns" and your "greens." Never, ever add dairy products, greasy foods or meat, which attract vermin when they rot.

    In this article, the reporter states that "Never, ever add dairy products, greasy foods or meat, which attract vermin when they rot."

    If you are doing hot composting (compost pile must maintains the temperature of 135 - 160 degree Fahrenheit), you can add meats and dairy into your hot compost bin. Now, how do you get your compost pile to heat up to 135-160 degree? Here is an article about <a target="_blank" href="http://planetgreen.discovery.com/home-garden/diy-hot-compost.html">How to make hot compost</a>

    Basically, hot composting done in the conventional way required a bit more works and a lot of space in the backyard. However, you can buy an automatic <a href="http://www.naturemill.com">compost bin</a> from www.naturemill.com and get the same results without all the mess and manual labor work. The NatureMill automatic hot compost bin heat the compost to 140-160 degree, aerate it, and mix it automatically. It also has an air filter for the smell.
