Acer pseudoplatanus, or sycamore maple, is not recommended to plant, due to invasive tendencies and the large quantities of seeds it can produce. This species is non-native to Ontario with a natural range in continental Europe and western Asia. They are not overly particular to one type of soil, but do best in well-drained soil, rich in organic matter. Sycamore maple trees are tolerant of salt and many pollutants, making them tolerant to urban settings and can be transplanted with some ease. 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. For an alternative, consider planting Acer rubrum, Acer miyabei, sugar maple, and silver maple.
