Excerpt: ... ORCHID-GROWER'S MANUAL. INTEODUCTION. The nature and the habits of Orchidaceous plants are now better known than they were some few years ago, and we have become acquainted with the conditions of their growth in the countries where they are indigenous. There they are exposed to a dry season, during which they are at rest; and to a rainy season, when the heat is higher, and the air moist nearly to saturation. To grow Orchids in any perfection, their native climate must, to a certain extent, be imitated; viz. they must have a period of rest in a dry and comparatively cool atmosphere, and during their growth and flowering they should be exposed to a high moist atmosphere; but as they principally grow on the trunks and branches of trees, it is important that they should be exposed to a free current of air, and also to the light: this is essential, except in some few species which require shading, to prevent the plants being exposed to the direct action of the sun-s rays, which is apt to scorch the leaves. The great heat and moisture are only necessary while the plants are in vigorous growth, and this period should be during spring and summer, the best periods of rest being from-S B i about November till February; and it is the long period of rest which predisposes the plant to blossom. Of course, the rules as to the periods of growth and rest can only be stated in general terms. There are certain kinds which do not entirely cease growing throughout the whole year. And again, even of those which do go to rest periodically, on the completion of their growth, it does not always happen that their time of rest corresponds with that at which the largest numbers go to rest. Directions for the period of Growth. When the growing season commences, raise the temperature...
