If your space is limited, plant only vegetables that are liked by your family, but keep nutrition in mind. You might find it helpful to draw a garden diagram to find out if you have enough space to grow needed quantities. Don't forget repeat plantings. Some vegetables may be planted each month. This will greatly decrease the amount of space needed and keep the garden full for its most efficient use.
Many gardeners tend to stop after they have harvested their spring-planted crop.
This is a serious mistake. Many crops that are normally planted in the spring grow as well or better in the fall. While insects and diseases are sometimes more of a problem in early fall, yields and quality are often better than in the spring. Spacing of vegetables will be different with various cultivation methods. Tractors need wide rows.
