Rock Garden. Many persons labour under the impression thatthe rock garden does not require constant attention. To successfullydevelop a rock garden planting requires more thorough knowledgeof plants than the development of the refined flower garden or theinformal garden. The reason for this is that those plants whichsucceed in the rock garden development are much more uncommonthan the plants which succeed in other types of gardens and less oppor-tunity is afforded for intelligent study of their habits of growth andflowering characteristics. The rock garden, like the wild garden, isoften thought of as a garden in which plants enter into a competitionfor "the survival of the fittest." Quite to the contrary, intelligentmaintenance must be applied in order to eventually develop the planas originally intended. Most of the plants adapted to the rockgarden are the dwarf, slow-growing types which continue to becomelarger from year to year. They must be kept within bounds by intelli-gent pruning which will not destroy their effect. Occasionally manyplants are introduced into the rock garden planting which requiremuch more attention on account of the water which is necessaryfor their normal growth. A rock garden is not a garden from whichflowers are to be picked. The period of bloom is usually the periodwhen the plant is most valuable for its effect in the garden and theflowers should not be removed at that time.
