The goal of proper fertilization is to promote stronger healthier plants that will thrive and survive any adverse weather conditions or minor insect or disease problems. Fertilization over time will promote growth in plant size, which is desirable for most plants in a proper location. Some plants, however, must have their size and shape controlled to maintain a natural, but conforming appearance. Examples would be in front of the house so plants don’t block windows, or in shrub beds that may get too crowded.
