The successful cultivation of plants depends upon a great variety of conditions essential to their perfect development, such as climate, soil, and general treatment. We devote a few pages to the consideration of each of these conditions in their relation to plant life. These paragraphs are necessarily brief, but we have endeavoured to condense as much information in them as the space at our disposal will admit of; and we have confined ourselves to simple explanations or directions, as the case may be, for the use of those possessing little practical knowledge.
