A lush green hedge is one of the most useful things you can plant. It marks the garden boundary without screaming about it. It cools the air on hot days. It creates a backdrop for everything else you plant. And when it's right, it makes the whole garden feel finished.
Five Hedge Plants That Deliver
The Ficus Hillii is the standard for a fast, dense green hedge that clips clean. Plant 80cm-1m apart for a useable screen in two summers.
The Waterhousea floribunda gives a native alternative with a soft weeping habit, ideal for relaxed gardens.
The Murraya paniculata is the right pick for lower hedges (2-3m), with the bonus of fragrant white flowers.
The Bay Tree is the slow but tidy option. Less work over time and a refined finish.
The Syzygium australe 'Resilience' is the native standard for warmer climates, with fine glossy foliage and pink new growth.
How to Plant a Hedge That Lasts
Four rules for a long-lived hedge:
-
Prepare the whole trench, not individual holes. A continuous trench gives roots room to spread and the hedge fills in evenly.
-
Improve the soil before planting. Compost, well-rotted manure, and a slow-release native or general fertiliser at planting.
-
Mulch the whole hedge line. Don't leave bare soil between plants.
-
Water deeply, not frequently. Twice a week in the first summer.
How to Get a Dense Hedge
The big mistake is letting hedges grow to height before encouraging width. Do the opposite. Trim the top lightly from the second season to slow vertical growth and force lower branches to thicken. A dense hedge is built from the bottom up.
Trimming Schedule
Most green hedges want two trims a year:
-
Spring trim: after the first growth flush, late spring.
-
Autumn trim: mid-autumn, before cooler weather.
Bay needs only one trim a year. Murraya benefits from a light trim after each flowering flush.
FAQ
How tall can my hedge get?
Most reach 3-5m comfortably. Ficus and Waterhousea can go taller.
Can I plant a hedge in clay?
Most of these will adapt, but Ficus and Bay don't like waterlogged ground. Lift planting heights and improve drainage.
How wide should the hedge be?
Plan for the mature width: 1m for Murraya, 1.5-2m for most others. Always slightly wider at the base than the top for healthy growth.
Final Word
A lush green hedge takes patience for the first 18 months and almost nothing after that. Pick the right species, plant it well, and the hedge becomes the most reliable feature in the garden.
