Quick Reference
- Most formal/dense evergreen hedges: 30–60 cm between plants
- Wider-canopy shrubs (Photinia, Viburnum, Leyland Cypress): 60–120 cm
- Fast growers close spacing = faster fill but more frequent pruning
- Always add 10–15 cm buffer from walls/fences beyond the plant's mature width
- Rule of thumb: spacing ≈ 1/2 to 2/3 of the plant's expected mature width

| Goal | Recommended Spacing Ratio | Notes |
|---|---|---|
| Fast privacy screen | Tighter end of range | More plants, faster fill, more pruning |
| Formal clipped hedge | Consistent mid-range spacing | Uniformity matters more than speed |
| Low-maintenance informal hedge | Wider end of range | Fewer plants, less pruning, natural gaps |
| Near structures/walls | Mature width ÷ 2, +15 cm buffer | Prevents foundation/wall damage |
| Pot/container hedging | Reduce spacing by ~20% | Root space is already constrained by pot |
| Symptom | Likely Cause | Fix |
|---|---|---|
| Bare/leggy lower branches | Overcrowding, low light penetration | Thin selectively, increase spacing on replant |
| Uneven hedge line | Inconsistent spacing at planting | Transplant outliers, re-measure with string line |
| Slow to fill in | Spacing too wide for growth rate | Fine for informal hedges; interplant if formal look needed |
| Fungal spotting / disease | Poor air circulation from tight spacing | Increase spacing, prune interior for airflow |
| Frequent pest issues | Overcrowded roots competing for nutrients | Thin plants, feed and mulch remaining hedge |
| Hedge dying from the inside out | Long-term overcrowding, sunlight starvation | Renovation-prune or replace inner-shaded plants |
Q: Is spacing the same for all evergreen hedges? No — it scales with mature width and growth rate. A slow, narrow grower like boxwood needs half the spacing of a wide, fast grower like Leyland Cypress.
Q: Should I space tighter than recommended for a "fuller" hedge sooner? You can go 10–15% tighter for faster fill, but expect more frequent pruning and higher disease risk from reduced airflow.
Q: How much closer can container/pot hedges be planted? Roughly 20% closer than in-ground spacing, since pots already restrict root spread — but expect more frequent feeding and watering.
Q: Does climate change these numbers? Yes — colder, drier, or windier regions generally favor the wider end of any spacing range to reduce stress and improve frost/wind resilience.
