Root Spread of Large Lime (Linden) Tree: 2–3× Dripline Radius

How Far Do Roots of a 100-Foot Lime Tree Extend?

A question about root span of a 100-foot lime (linden) tree.

Root Zone Geometry

• Roots concentrate in top 18 inches (oxygen zone).
• Horizontal spread = 2–3× distance from trunk to dripline.
• Dripline = outer edge of canopy.

Example

If canopy radius = 30 ft, roots extend 60–90 ft from trunk. Not a uniform circle—roots follow moisture, soil pores, and avoid obstacles.

Practical Implication

Construction, grading, or trenching within this zone risks tree stability and health. Protect a radius of at least 1.5× canopy radius for critical root zone.
