When to Trim Box Hedges in Australia
Box Hedges (Buxus, English Box, Japanese Box) are formal evergreen plants that require regular trimming to maintain shape and density. In Australia, the best time to trim Box Hedges is during their active growing season โ spring through early autumn. Cutting at the right time keeps hedges compact and encourages fresh flushes of new growth.
Seasonal Trimming Guide
- Spring: First major trim of the year, shaping hedges as growth resumes after winter.
- Summer: Light trims every 6โ8 weeks maintain density and keep hedges neat.
- Autumn: Final tidy-up before cooler weather slows growth.
Avoid heavy pruning in winter, especially in frost-prone areas, as recovery is slow and exposed cuts may be damaged.


Fertiliser for Box Hedge Recovery
Every trim forces Box Hedges to produce new leaves, which increases nutrient demand. Fertiliser after trimming is essential for quick recovery, dense foliage, and even regrowth.
The best choice is Complete Grow All Purpose Liquid NPK 20-20-20, a balanced liquid fertiliser that provides:
- Nitrogen: Fuels fresh green leaf growth after each cut.
- Phosphorus: Strengthens roots to support ongoing trimming cycles.
- Potassium: Improves leaf thickness and colour for a healthy, glossy hedge.
Apply fertiliser within a week of trimming, then continue feeding every 4โ6 weeks through spring and summer. This keeps Box Hedges lush, resilient, and able to handle repeated shaping.


Trimming Mistakes to Avoid
- Cutting too hard: Deep cuts into old wood take months to recover and may leave gaps.
- Pruning at the wrong time: Heavy cuts in winter or extreme summer heat stress plants.
- Not fertilising after trimming: Hedges often remain sparse and slow to regrow.
A light, consistent trimming schedule supported by fertiliser is always better than infrequent heavy cuts. Pair each trim with Complete Grow 20-20-20 to keep Box Hedges strong and vibrant.
