Acer japonicum, or Japanese maple, is a non-native species originating from Northern Japan. It is considered an emerging invasive in the Mid-Atlantic states, and there are some indications the rootstock has the potential to become an issue in Ontario. It prefers a moist, well-drained soil between the pH range of 6.0-7.5. 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. It is commonly found in the nursery trade, known for its striking foliage colour.
