Summarize the following:
To prepare garden compost without unsightly bins or piles, use a shovel to dig a trench in your garden approximately 12 inches (approximately 30 cm) deep. The compost will add nutrients and moisture to your soil, improving the quality of your plants. Choose an area that will get sunlight but not interfere with the rest of your garden. Trenches can be placed between plants, along shrub borders, or virtually anywhere else in the garden. Add approximately four to six inches (approximately 10-15 cm)of kitchen scraps to the bottom of the trench. Avoid adding bread products, meat, bones, dairy, rice, oils, or weeds. Opt to include fruit and vegetable scraps, and other ingredients such as: Egg shells, which will add calcium to the soil and deter snails and slugs with their sharp edges. Coffee grounds, which are rich in nitrogen and attract worms. Once you've added your composting materials, use a shovel to fill in the trench with soil. The composting process will occur without any additional work from you. It should take a period of a month to a year, depending on the volume and specific compost materials. Composting trenches should be moved to different locations in your garden every year. This will allow you to fertilize the entirety of your garden while continuing to grow new plants or flowers. Plan to have designated walking areas, plant areas, and trench areas that you can navigate around comfortably.
Dig a trench. Fill it with kitchen scraps. Cover the compost materials with soil. Move the trenches around each year.
