Planning the Vegetable Garden
How much time will you be able to devote to your garden on a regular basis? The answer to this question will dictate the size of your garden. You must remember that, once planted, the garden will have to be weeded once a week, irrigated during droughts, and vegetables harvested when ripe. Depending on the type of vegetables, you may also need to undertake pest control measures.

Soil Preparation
The ideal soil for a vegetable garden is deep, friable, and well-drained with a high organic matter content. Proper soil preparation provides the basis for good seed germination and the subsequent growth of garden crops. Careful use of various soil amendments can improve garden soil and provide the best possible starting ground for your crops.
