Acer negundo, or Manitoba/ boxelder maple, is not recommended to plant as it spreads and dominates forest stands easily (weedy), despite being native to Canada. As a result, it is not commonly available in the nursery. Manitoba maple is a hardy and fast-growing tree, but is prone to storm damage which gives it a short life span. It prefers a well-drained loamy soil, and can tolerate a range of soil types, however, it performs best in nutrient-rich, slightly acidic to neutral soil. 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. The Auditor General of Ontario has specifically flagged this tree species as a concern in the nursery trades ("Value-for-Money Audit � Management of Invasive Species," 2022) and as such should not be recommended for planting. For an alternative native tree species, consider Amelanchier spp., or Acer rubrum.
