Selecting a Planting Site for a Large Tree

  • Choose a location with at least 40 feet of open space.
  • Leave at least 15 feet between the tree, sidewalks and hardscapes.
  • Do not plant beneath utility lines or near streetlights, signs, etc.

If you cannot plant your tree in the ground within 24 hours, plant it in a pot with potting soil temporarily so it will survive until you find the right spot.
