Vegetable gardening is the relaxing art and science of turning a love for growing plants into a worthwhile activity.Vegetable gardeners agree that many homegrown vegetables picked at their best are better than those vegetables bought from markets. From spring through late fall, a well-planned and well-kept garden can provide a supply of fresh vegetables, thus increasing the nutrition (营养) of the family diet. Freezers make it possible to keep some of the vegetables to be enjoyed at a later date. Other vegetables Call be stored for a few months in a cool area.Having vegetables in the backyard makes home gardening attractive for many people. Besides, vegetable gardening provides exercise and fun for families. Although the money spent on a garden may be little, one cannot escape the fact that gardening requires hard work and time. Many of the gardening tasks must be performed at times that are most inconvenient. Not doing jobs that should be done on a regular basis may result in failure and a negative (消极的) feeling toward gardening.One should not plant a garden that is too large for one to care for. A small, well-kept garden is more enjoyable and profitable (有益的) than a large one. Vegetables do well in full sunlight and need at least five or six hours of sun during the middle of the day. Too much shading results in poor plants and few vegetables. If possible, the garden should be near the house 80 the gardener can work in it at irregular moments.Usually the homeowner has little choice in the soil type. Fortunately, many vegetables can be grown on poor soil if the soil is properly prepared.
