Drought Tolerant Container Plants

Alpine troughs are becoming increasingly popular because of their practicality. They take up a small amount of space and require little attention, as these kinds of plants thrive in lean, well-drained soil and don’t need much water. Many people don’t realize that rock-garden plants are available in a great variety of textures and colours. Look for a new line called Rock Stars, all alpine and rock garden plants, many of which are ideal for containers.

Care: This trough will give you several years of enjoyment if excellent drainage is provided. Be sure the container is raised off the deck to allow free drainage and tuck it under the eaves to protect it from winter rain. Cut back finished foliage of the deciduous plants. These plants become leggy with too rich a diet, so top-dress with controlled-release fertilizer very sparingly and only if the plants look yellow in spring.
