Acer rubrum, or red maple, is native to Ontario and ranges throughout eastern North America, thriving on a wide range of soil types and tolerating wet, flooded soils for prolonged periods of time. They are commonly found in the nursery industry and are ideal to plant in urban environments. Not recommended for urban areas with alkaline, and fine textured soils (chlorosis generally occurs). The species can be easily transplanted. It is advisable to prune in the late spring (June), as cutting may cause sap to leak from the wounds. While this can impact the tree's appearance, it does not harm the tree.
Can develop chlorosis in alkaline soils Surface roots may heave pavement Thin bark is sensitive to injury
