　　No one plan or arrangement for a garden can suit all conditions. Each gardener must plan to meet his own problem. Careful planning will lessen the work of gardening and increase the returns from the labor. Planting seeds and plants at random always results in waste and disappointment. Suggestions for planning a garden are here presented with the idea that they can be changed to suit the individual gardener.

　　The first consideration is whether the garden is to be in one unit or in two. With two plots, lettuce, radishes, beets, spinach, and other vegetables requiring little space are grown in a small kitchen garden, and potatoes, sweet corn, pumpkins, melons, and other vegetables requiring more room are planted in a separate patch, as between young orchard-tree rows or in other areas where conditions are especially suitable for their culture.

　　The cultivation methods to be employed are important in planning the garden. When the work is to be done mainly with a garden tractor, the site and the arrangement should be such as to give the longest practicable rows. On slopes of more than 1 1/2 percent, especially on light-textured soil, the rows should not cross the paths, and turning spaces of 10 to 12 feet should be provided at the ends. The rows for small-growing crops may be closer together for hand cultivation than for cultivation with power equipment.

　　Any great variation in the composition of the soil within the garden should be taken into consideration when deciding on where to plant various crops. If part of the land is low and moist such crops as celery, onions, and late cucumbers should be placed there. If part is high, warm, and dry, that is the proper spot for early crops, especially those needing a soil that warms up quickly.

　　Tall-growing crops should be planted where they will not shade or interfere with the growth of smaller crops. There seems to be little choice as to whether the rows do or do not run in a general east-and-west or in a general north-and-south direction, but they should conform to the contours of the land.
