Understanding these species’ general characteristics will help you determine if a cultivar may be a good fit for your landscape. There are several parent species from which maple hybrids and cultivars are derived. When selecting a tree for your landscape, choose a cultivar that is well adapted to your soil and conditions. If left untreated, branch death or even tree death can occur. This nutrient deficiency causes yellowing leaves (chlorosis) with green veins, and in extreme conditions, can cause death of leaf edges. A common problem associated with maples in the Intermountain West is iron chlorosis (Figure 1). In Utah, high pH is common and may cause some micronutrients, particularly iron, to be less available, making it difficult for certain trees to take up needed nutrients. Soil chemistry and characteristics are important considerations when choosing maple trees. There are many factors to consider when selecting a maple for your landscape, including tree size, leaf color, fall foliage color, leaf shape, and disease resistance.

Fall colors typically range from yellow to bright red, adding a burst of color to the landscape late in the season.įigure 1.
Maples can create a focal point and ornamental interest in the landscape, providing interesting textures and colors, and of course, shade. Because trees come in a range of shapes and sizes, there is almost always a spot in a landscape that can be enhanced by the addition of a maple. Tree shape can vary greatly, ranging from upright, columnar, rounded, pyramidal to spreading. Trees vary in size and shape, from small, almost prostrate forms like certain Japanese maples (Acer palmatum) and shrubby bigtooth maples (Acer grandidentatum) to large and stately shade trees like the Norway maple (Acer platanoides). There are over one hundred species, each with numerous cultivars (cultivated varieties) that are native to both North America and much of Northern Europe. Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes.
