What can I plant instead of ash?

The best tree to plant to replace an ash tree depends on climate (i.e. where you live), the location the tree will be planted in, and other considerations like spacing (how big a tree will fit) and aesthetics.

The plant hardiness zone and annual rainfall will determine the range of tree species that will be suitable for you to plant. It is important to pick the right tree for the specific location that you will be planting it. A well chosen tree is more likely to survive and thrive, and will require less maintenance. Have a look at the location you want to plant the tree:

  • Does the soil drain well or does it tend to be wet?
  • Is the soil very sandy, more clay-like or somewhere in between?
  • How much direct light will it receive - full sun, partial sun or full shade?

A list of suitable tree species for your local area, and their preferred growing conditions, may be available from your municipality, or look through the resources listed below. Local tree nurseries or tree care companies are also resources for suitable replacement trees.

Do not plant any species of ash (Fraxinus) at this time. Some tree species, such as Norway maple, white poplar and Siberian elm, are considered invasive (i.e. they may invade new ground, negatively impacting other species). Though they may be available at tree nurseries, it is best not to plant these tree species either.
