GARDENING.
1092. Proper situation for a Green-House.—The aspect of a green-house may be at any point from east to west, following the course of the sun; or, it may even be a little to the north of east or west; but only a little, and the less the better, otherwise the plants will not generally thrive in it, nor will the flowers acquire their natural colors. A south aspect is to be preferred.
1093. On preserving Seeds of Plants in a state fit for Vegetation.—Seeds of plants may be preserved, for many months at least, by causing them to be packed, either in husks, pods, &c., in absorbent paper, with raisins or brown moist sugar; or, a good way, practised by gardeners, is to wrap the seed in brown paper or cartridge paper, pasted down, and then varnished over.
1094. To facilitate the Growth of Foreign Seeds.—Mr. Humboldt has found, that seeds which do not commonly germinate in our climate, or in our hot-houses, and which, of course, we cannot raise for our gardens, or hope to naturalize in our fields, become capable of germinating, when immersed for some days in a weak, oxygenized muriatic acid. This interesting discovery has already turned to advantage in several botanic gardens.
1095. To plant and make Edgings.—Edgings of daisies, thrift, violets, gentianella, &c., should be planted in February; but those of box succeed better, if planted in April or August.
