Your soil will be predominantly either sandy, loamy, or clayey. If you have sandy or clay soil in your garden, you will need to add amendments to improve the soil texture. This is necessary to allow for the retention of adequate moisture and nutrients in sandy soil and to provide proper drainage in clay soil. The very best organic soil amendment is compost from your own compost bin, if available. There are many kinds of organic fertilizers, from kelp and fish meal to earth worm castings and bat guano.
Some organic fertilizers have high nitrogen levels and low amounts of phosphorus.
Others are more balanced. Base your choice of fertilizers on the needs of the plants in your garden. Organic gardeners use a variety of methods to control insect pests. It is very important to learn to distinguish pests from beneficial insects. A good example of insect management using an organic method is a Japanese beetle trap placed upwind 50 to 100 feet from a garden.
