Why Tree Roots Are Often Misunderstood
Why this topic matters
Tree roots are responsible for most of a tree’s health and stability, yet they’re also the least visible part of the system — and the most misunderstood.
Misunderstanding roots often leads to incorrect assumptions about risk and tree behavior.
What homeowners don’t realize
Most tree roots:
- grow outward, not downward
- search for water and nutrients
- exist primarily in the top 30–45 cm of soil
Fibrous (absorbing) roots can extend 1.5× or more beyond the canopy width.
Buttress and structural roots grow downward and outward to anchor the tree.
Trade-offs & realities
Because roots are hidden:
- damage often goes unnoticed
- symptoms appear years later
- cause-and-effect is hard to connect
Once root systems are compromised, recovery options can be limited.
How we approach this at Driftwood
We consider:
- soil condition and compaction
- root zone disturbance
- available rooting space
- long-term site changes
This helps us explain why a tree is behaving the way it is — even when the canopy looks fine.
Bottom line
Roots are rarely doing what people imagine — but when they’re stressed or damaged, the effects matter.
