Planting a Privacy Hedge Near a Large Douglas Fir

A homeowner in the Pacific Northwest wants to replace a dying cedar hedge with a 5-foot yew (Taxus) hedge planted at 2-foot intervals along a property line. A massive 150-foot Douglas fir sits just 3 feet from the sidewalk, with large roots lifting the pavement. The planting trench reveals limited rooting space. They ask if yew or any hedge can survive there, or if a fence is the only option.

Expert Advice

The space is too constrained for most trees; the fir’s roots will outcompete any hedge for water and nutrients, and overhanging branches will create sidewalk clearance issues. A fence is the most practical solution.

Alternative: Privet Hedge

If greenery is preferred, a privet hedge (Ligustrum) can tolerate partial shade and tight spaces, provided it receives regular pruning and consistent moisture. Privet forms a dense, impenetrable screen within a few years.

Planting Steps for Privet

1. Prepare site in full sun to partial shade; soil should be moist but well-drained (avoid pure sand).
2. Space plants 12 inches apart, at least 18 inches from sidewalks or walls.
3. Dig holes, add a shovelful of compost to each, and mix with native soil.
4. Plant at same depth as in container; backfill halfway, firm soil, water, then finish backfilling.
5. Create a soil berm around each plant to hold water; water thoroughly twice.
6. Water every other day for two weeks, then provide 1 inch of water weekly.
