How Far Apart to Plant Box Hedges in Australia
Correct spacing is the foundation of a dense, even Box Hedge. Planting too far apart leaves gaps, while planting too close forces plants to compete for water and nutrients. The ideal spacing depends on the hedge style, the Box variety (English, Japanese, Korean), and how quickly you want the hedge to fill in.
General Spacing Guidelines
- Formal low borders (20โ40 cm high): 20โ25 cm apart for tight edges.
- Standard hedges (60 cm โ 1 m high): 30โ40 cm apart for even density.
- Taller hedges (1 m+): 40โ50 cm apart for strong long-term growth.
For quick results, plant closer together. For long-term low-maintenance hedges, allow more space so roots and foliage donโt overcrowd.


How to Plant Box Hedges
Spacing is only one part of successful planting. To establish a Box Hedge that grows evenly and stays healthy, preparation is key.
- Mark a straight line with string before planting for accuracy.
- Dig holes twice the width of the root ball but not deeper.
- Set plants at the same soil depth they were growing in the pot.
- Backfill with improved soil, firm gently, and water thoroughly.
- Mulch lightly around the base to retain moisture but keep stems clear.
English Box is slower growing, so planting slightly closer gives quicker hedge density. Japanese Box is faster and can be spaced wider if patience allows.


Fertiliser for Quick Establishment
Box Hedges need extra nutrients during the first 1โ2 years to close gaps and establish evenly. A balanced liquid fertiliser like Complete Grow All Purpose Liquid NPK 20-20-20 is ideal for this stage. It delivers nitrogen for leafy growth, phosphorus for strong roots, and potassium for foliage health.
- Apply fertiliser at planting to reduce stress and boost root development.
- Feed every 4โ6 weeks during spring and summer until the hedge is fully established.
- Continue fertilising after each trim to encourage dense regrowth.
