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.
Because it is late spring before plants can survive outdoors in Southern Ontario, it is common for people to start their plants indoors. Seeds are planted in small containers and continue to grow indoors until the appropriate size is achieved. Sometimes ultraviolet light is used to encourage plant growth. When the mercury rises and the danger of frost is past, the plants are then transplanted to the garden or to a flowerbed.
