The details of horticultural practice naturally range under the three
heads of flowers, fruits and vegetables (see also FRUIT AND FLOWER
FARMING). There are, however, certain general aspects of the subject

each department. We shall therefore first treat of these under four
headings: formation and preparation of the garden, garden structures and
edifices, garden materials and appliances, and garden operations.
