Backyard Composting

Reap a Heap of Benefits

Composting is a lot easier than you may think. Organic material breaks down around us in nature all the time. Composting is just a method of speeding up the process.

Most compost bin designs are so simple they can be built in a few hours. Once you gather your yard waste and form it into a pile, the only time you'll spend is for occasional maintenance. Then sit back and let nature do the rest.

Composting Equipment


Tools

All you need are some basic gardening tools, like a pitchfork, a rake, and a shovel.

Materials

Compost bins can be built with inexpensive materials like snow fencing, woven wire, or used cinder blocks and lumber.

Soil

You don't need store-bought "soil activators" or potting soil to compost. One inch of soil from your yard or garden has all the ingredients needed to start the composting process.

Compost is ready to harvest when it is reduced to a crumbly, sweet smelling material called humus. If some pieces are not decomposed, you can sift those out and use them to start a new batch.

Compost improves soil structure, holds in moisture and plant nutrients, and promotes strong, healthy root systems for plant growth.

Composting with Coffee Grounds

Coffee grounds can provide a valuable source of nutrition for your garden if used properly. The proper amount to be used depends on the condition of the soil and, more specifically, what you are growing in your garden. Check with your local gardening expert to see what is best for your situation.


Coffee grounds can be applied directly in the garden along with other materials as a side dressing for vegetables, roses, or other plants.

Coffee grounds are high in nitrogen, but are also acidic. Adding brown material such as leaves and dried grass to the mulch will help keep a balanced soil pH.


Coffee grounds act as green material with a carbon-nitrogen (C-N) ratio of 20-1, when mixed in with your compost. Combined with browns such as leaves and straw, coffee grounds generate heat and will speed up the composting process.
