Live Oak Spacing and Power Line Conflicts in Houston

Second Opinion: Same Live Oak Question, Clearer Answer

Same Katy, TX homeowner: 6 live oaks, 65-gallon, 8-ft spacing, 20-ft power lines, screening a water motor.

Direct Answer

No. Do not plant live oaks under power lines.

• Mature height: 60–90 ft
• Deciduous in practice (heavy fall leaf drop)
• Bottom branches rise with age—no low screening
• Short-lived for oaks (20–25 years typical for Bradford types)

Better Strategy

• Plant conifers (pines, spruces, firs) for year-round evergreen screening
• If space allows, mix oaks + evergreens for diversity
• Choose 45-gallon over 65-gallon – easier to handle, establishes faster

Screening Tree Reality

For a 9-ft motor unit viewed from second floor, you need a 15–20 ft evergreen hedge/tree line—not canopy trees that shade out their own lower branches.
