They have received an OPALS* allergy scale rating of three or lower: The following cultivars are entirely female, and have a low potential for causing allergies. They have received an OPALS* allergy scale rating of eight or higher: The following cultivars are entirely male, and considered highly allergenic. The allergenic potential of red maple varies widely based on the selection of cultivar. Red maple is sensitive to fire injury large trees can be killed by a fire of moderate intensity. Common leaf feeding moths include gypsy moth, linden looper, elm spanworm, and red maple spanworm. Scale insects that are attracted to red maple include the cottony maple scale, the maple leaf scale, and the oystershell scale. Borers that feed on red maple include the gallmaking maple borer, maple callus borer, and the Columbian timber beetle. It may also hasten the decline of weakened trees. Prolonged infestation can reduce vigor and growth, increasing the tree’s susceptibility to fungal infections. Increment boring can cause discoloration, which often results in decay. Many different insects feed on red maple, though none have the capacity to decimate a healthy tree.
Red maple is also vulnerable to many leaf diseases, particularly anthracnose, and leaf spot. Heart rot is a common affliction of red maple Phellinus igniarius is one of the leading causes. The fungi Inonotus glomeratus and Oxyporous populinus infect branch stubs, and wounds on the stem. Red maple is susceptible to rot fungi and stem diseases. Red maple develops best on moderately well-drained, moist sites at low to intermediate elevations. On some individuals, chlorosis can occur on very alkaline soils. It develops in soils derived from granite, gneiss, schist, sandstone, shale, slate, conglomerate, quartzite, and limestone. It can withstand soils of various textures, moisture, pH, and elevation.
Red maple can thrive in a wide range of soil types, more than any other tree in eastern North America. Red maples maintain this characteristic root system adaptability as they mature. Mature trees have woody roots up to eighty feet long. On dry sites, seedlings develop long taproots, with significantly shorter lateral roots. In wet locations, red maple seedlings produce short taproots, with large, well-developed lateral roots. Roots are primarily horizontal, forming in the upper ten inches of the soil. The roots of red maple are capable of adapting to different environments, enabling seedlings to survive in a myriad of settings. In forests across much of the eastern United States, red maple has been displacing deciduous trees like oaks, as well as pines and hickories. Red maple can be considered weedy or invasive. Due to its striking features, and adaptability, it is often used as a shade tree for landscapes. Red maple flourishes in a wide range of site and soil conditions more so than any other tree in eastern North America. Its most distinguishing characteristic is its brilliant deep scarlet foliage in autumn. Red maple’s flowers, petioles, twigs, and seeds are appealing shades of red. This is especially noticeable on the many red maple cultivars available for selection. Many of its features are variable in form. Forest Service recognizes it as the most common species of tree in the United States.
Red maple ( Acer rubrum), also known as swamp maple, water maple, Drummond red maple, Carolina red maple, or soft maple, is one of the most widespread deciduous trees of eastern and central North America. The following examines the tree’s root development, soil and topography, damaging agents and pests, allergenic potential, and additional uses.
