For at least ten thousand years, people have cultivated gardens, growing food and medicinal plants, fruit and ornamental trees, and always flowers. During this long time, gardening has become ingrained in people's blood. For many, this tendency manifests itself from a young age, while others find themselves relaxing and enjoying life among plants only in their later years. Gardeners are a consistent, thoughtful, and resourceful people. Through millennia of continuous practice, they have learned by trial and error to change the surface of their land, improve soil fertility, and protect plants against wind, excessive sunlight, cold, plant diseases, and pests. Valuable species of edible and ornamental plants have gradually expanded their growing areas from country to country, from one culture to another, even crossing intercontinental oceans, and gardeners have always found a way to grow delicate southern plants in their local climates.
