![]() ![]() They are considered somewhat shallowrooted, and roots may interfere with sidewalks and other landscape plants. Norway maple is probably the most commonly planted maple in the Intermountain West. Norway maple (Acer platanoides): This group of maples is well adapted to the Intermountain West and is typically tolerant of alkaline soil and arid climate. For specific cultivar recommendations, see Table 1.įigure 2. 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. ![]() Of the beginning of tissue necrosis from a chronic Interveinal chlorosis characterized by the yellow leavesĪnd green veins. 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. ∜elzam outgrew all other cultivars despite soil treatments and ∛owhall was unaffected by compaction, but did not produce aesthetically pleasing specimens.Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes. Generally, all cultivars growing in the un-compacted plots had a significantly larger mean caliper and higher values for leaf biomass measures than trees growing in the compacted plots. Genetics is the primary factor controlling plant response to compaction for all biomass measures. We compacted field plots to bulk densities considered restrictive to tree growth and left the control plots at the pre-existing bulk densities.Īlong with measuring tree growth factors, we also measured various soil attributes. Red and Freeman maple ( Acer rubrum and Acer × freemanii) cultivars were chosen for the study because they are commonly planted for their attractive fall color and overall versatility.įreeman maple is a naturally occurring hybrid of red and silver maples, and is often touted as being more tolerant of difficult urban sites than either parent. The objectives of this study were to assess the effects of compaction on tree establishment and growth and to characterize soil factors that contribute to lack of vigor. ![]() Compaction is often indicated as a widespread problem in urban and suburban landscapes.Ĭonstruction activities, foot and vehicular traffic and limited mulching all may contribute to compaction.
