Gardening may be pursued either as a hobby or as a career. To the modern urban world, gardening is a hobby, a relaxing escape from the pressures of an urban environment. To a vocational gardener, gardening may be an enjoyable vocation. Whatever may be the reason behind the gardening activity, undoubtedly, growing flowers, fresh vegetables, herbs, and fruits, provides a great sense of joy, relaxation and accomplishment. In horticulture, gardening is defined as the practice of growing and cultivating plants. In gardens, ornamental plants are often grown for their flowers, foliage, or overall appearance, while other useful plants such as root vegetables, leafy vegetables, fruit plants, and herbs are grown for consumption purposes. There are certain other plants that are grown for use as dyes, or for their medicinal or cosmetic properties.
