Compost is organic material that has decomposed to become rich soil or mulch. Most gardeners choose to make their own compost at home by recycling kitchen and yard waste and other organic matter in their backyards in a pile known as compost. Some choose to spend money on special composters so the decaying matter isn't in plain view. A few even use worm bins in their homes for composting household waste.

If you employ the use of a compost bin or pile, give yourself a pat on the back. Not only does compost provide rich nutrients and moisture to the plants in your garden, but it also recycles items that might otherwise be discarded. In addition to benefiting your plants and garden, you're also benefiting the environment as compost reduces landfill. When spread out over your soil and around plants, compost will continue to break down for years, providing long-term nutrition that your plants can't get from fertilizer.

If you've been contemplating starting your own compost heap, but are afraid it will cause your back yard to smell, you couldn't be more wrong. If aerated properly, compost should have a sweet smell. In order to prevent the stench of rotting food, you'll want to avoid putting meat, fish, or the feces of carnivorous animals into your compost heap.

Here is a brief list of things ideal for composting:

• Green Matter - Grass clippings, tree and other yard trimmings, vegetable peelings and other remains such as carrot tops and pith from fruit such as oranges, rotted fruits, vegetables, weeds
• Brown Matter — leaves, nut shells, saw dust, shredded or chipped wood (wood must be untreated), dead flowers and plants, pine needles, straw
• Other — Manure from plant-eating animals such as cows or sheep, egg shells, tea bags, coffee grinds

Here's an unusual list of items that can be composted - (most of these items are considered "brown" compost) - Newspapers, hair, dryer lint, certain vacuum cleaner dust, charcoal, used coffee filters, feathers, cotton rags, bedding from pet rodents, such as hamsters and gerbils, string

For a compost pile to work properly, it has to have the proper mixture of green and brown ingredients in alternating layers, with the other stuff thrown in for good measure. If composed with the correct ratio of brown and green matter, a compost heap will remain warm and damp. To keep the pile warm and damp, it must be turned regularly with a shovel or pitchfork. It takes at least six weeks for the organic material to compost enough to use in your garden, but it's recommended you wait at least a few months.

When your compost heap takes on a dark color, a crumbly texture and an earthy smell, this is a good indication it's ready to mix into your soil. Once you notice how your garden is flourishing, you'll have no problem beginning the process again.
