Proper spacing is important for both the health and appearance of perennials. Proper spacing allows for air to circulate around the plants and prevents disease. If planted too closely, perennials will have to compete with each other for water and essential nutrients in the soil. This kind of stress on a plant can also make it more vulnerable to disease and even winter loss. Recommended spacing makes weeding and care such as deadheading much easier. It is a common mistake to plant perennials too closely. Follow the plant spacing guideline provided on the label, and your perennials will be healthier and more attractive.
