Proper Tree Planting: Finding the Root Flare

Landscapers often plant balled-and-burlapped trees with one-third of the root ball above grade. This isn't new science — it's a technique to ensure the root flare (where trunk transitions to roots) sits at the correct soil level.

Why It Matters

Nursery digging often buries the flare under excess soil. Planting at the original growth depth prevents trunk rot, girdling roots, and long-term decline. Homeowners should gently excavate the top of the root ball before planting to locate the flare and position it slightly above surrounding soil.

Key Steps

1. Remove excess soil from top of root ball to expose flare.
2. Dig hole no deeper than the root ball height.
3. Set tree so flare is visible just above grade.
4. Backfill with native soil, water thoroughly.

Correct planting depth is critical for tree longevity.
