This is online pdf ebooks for download about organic gardening.

Organic gardening relies on ecological principles and natural processes to grow and manage garden crops. Although organic gardeners avoid the use of synthetic pesticides and fertilizers, organic gardening is not a list of substitutes for synthetic products or a set of home remedies to kill pests. Organic gardening is a holistic approach that involves understanding soil management, integrated pest management, and the life cycles of plants, pests, and the pests’ natural enemies. When properly done, organic gardening can produce high quality food and landscapes, enhance the garden environment, protect water quality, and conserve natural resources.
The basic soil management and pest management approaches of organic gardening make sense for all gardeners, whether you avoid all synthetic fertilizers and pesticides or not. Using these approaches will reduce the amount of fertilizers and pesticides you need, and can improve the quality of your garden.
Other benefits of organic gardening include increasing the number and diversity of beneficial organisms and turning waste materials into valuable composts and fertilizers for the garden.
Organic gardening means actively working with nature in your garden. Organic gardeners need to be smart gardeners—knowing the garden environment, observing plants and pests, knowing choices for management, and acting at the appropriate time.

A little planning can go a long way in gardening. Before you even head to the nursery, start by looking around your yard and taking note of which areas get a lot of sun, which are shaded all day, and which are sunlit for part of the day. Also, notice which spots tend to be damp all the time and which dry out very fast. Now you can use that information to choose the site of your new garden and the plants that will fare well there. When you select plants that thrive in your conditions, you have to care for them less.

Prepare your new garden beds before you buy your plants. Loosen the soil with a shovel, garden fork and/or tiller 6 to 8 inches deep, and add several inches of compost to it. If the soil is sandy, mix in an extra helping of compost. In most climates, vegetables, fruits and herbs grow best in raised beds, which are built up 4 to 6 inches above the surrounding ground. Most flowers thrive in raised beds, too. The soil in raised beds drains quickly so plants never sit in water, and the soil warms up fast in spring.

You can build a raised bed by adding a lot of organic matter to the soil and fluffing up the soil with a garden fork, then raking soil from the areas that will be paths up onto the beds. Many gardeners like to enclose their raised beds in wooden or plastic frames; others just mound up the soil. (Please don’t frame your garden with what’s commonly called “pressure-treated” CCA wood—it contains arsenic and other toxins that can leach into your soil.)
