The glossy pages of the catalogues provide a preview of the visual delights that can be grown. Pictures show an array of flowers that dazzle the eye. There are monochromatic displays as well as others that are a fusion of the complete spectrum of the rainbows colors. Also included in the publication are pictures and descriptions of vegetables, shrubs, and trees.
Avid gardeners subscribe to magazines that specialize in articles and ads about this enjoyable pastime and people literally read each issue from cover to cover.
Descriptions of plants include implicit instructions on whether to plant them in sun or shade. Specification as to the amount of irrigation required is also stated. Elaborate irrigation systems are sometimes installed or a trench for improving the water flow is used. Controls are needed on irrigation systems because if the ground becomes too saturated the soil in the garden will be too muddy to allow anyone to work in it until it dries out. If there is too much water constantly, the garden will become a swamp and impossible to cultivate.
Geographic location is important for plants. Certain plants are only suitable for propagation close to the equator. Others need to be several degrees of latitude away from the equator. Longitude is also a factor and most companies clearly state the conditions that will provide the optimum chances for the plants survival. Canadians grow tulips imported from Holland and they do well in the Southern Ontario climate.
