Some plants, like elm trees, have very vigorous root systems. If planted within 50 yards of water or sewer lines, elm roots can grow into the pipes, either cracking or clogging them. Whether views are good or bad will determine where you place plants. If your property is attractive, you may want to leave views of it open. If you sit on your patio and view your neighbor's garbage cans, plant a shrub screen to hide this or other unattractive views.
Environmental factors have a great influence on plant placement and choice.
An attractive, healthy plant placed in an unsuitable site may have poor growth, disease, and insect problems, or it can die. This might occur from too much shade or sun, poor water drainage, or poor fertility. These are some examples of the careful thinking you must do to design a landscape. Careful consideration of these and other features of your property will help to prevent later problems. In site analysis, you are assessing both the negative and positive aspects of your property and how to downplay or highlight them successfully with landscape plants.
