Planting Trees Correctly: Wide Hole, No Amendments, Find the Flare

Fall is ideal for tree planting. Follow these research-backed steps:

Dig a Wide Area, Not a Deep Hole

Loosen soil in a 6-ft diameter spiral. Only the center needs a hole twice the root ball width. Wide, pulverized soil encourages lateral root growth.

Skip Organic Amendments in the Hole

Research shows amendments don't help (except in sand). In clay, roots may stay in the rich hole and never explore native soil. Oxygen-rich, loose soil is what roots need.

Add Lime & Phosphorus While Digging

Scatter 4 lbs lime + ¼ cup 0-46-0 (or starter fertilizer) over the loosened area. Mix in as you dig. Roots access nutrients immediately.

Choose a Healthy B&B Tree

Fall-dug balled-and-burlapped trees have better root systems than spring container trees that sat all summer.

Find the Root Flare

Excavate at the trunk base until the flare (where trunk widens to roots) is visible. Set flare level with surrounding soil.

Remove Burlap, String & Wire Cage Top

Remove all burlap and string from the trunk. Wire cage can stay. Water thoroughly, mulch, and enjoy for generations.
