What do you call the depth of the soil when planting trees?

The depth of the soil when planting trees is commonly referred to as "planting depth." It is crucial to plant a tree at the appropriate depth to ensure proper root development and to avoid issues such as girdling roots or waterlogging. Generally, the planting depth should allow the root flare (where the roots meet the trunk) to be at or slightly above the soil surface. Proper planting depth is essential for the tree's long-term health and stability.
