When to Prune Viburnum in Australia
Pruning Viburnum at the right time keeps hedges dense, colourful, and healthy. In Australia, Viburnum grows actively through spring and summer, which makes these the best seasons for pruning. Cutting at the wrong time can slow growth or reduce flowering, while pruning correctly combined with fertiliser creates strong flushes of new foliage.
Seasonal Pruning Guide
- Spring: Light pruning encourages new shoots and sets the shape for the season.
- Summer: Trim after each growth flush to maintain hedge density and prevent legginess.
- Autumn: Final trim before cooler weather keeps the hedge neat going into winter.
Avoid heavy pruning in winter, as growth slows and new shoots may be damaged by frost in colder regions.
Why Fertiliser Is Essential After Trimming
Every pruning cut forces the plant to produce fresh leaves, which places a higher demand on nutrients. Without fertiliser support, new shoots appear weak, pale, or sparse. Feeding directly after pruning ensures Viburnum grows back quickly and evenly.
The best option is Complete Grow All Purpose Liquid NPK 20-20-20. This fertiliser provides nitrogen for rapid leaf growth, phosphorus for root strength, and potassium for healthy, disease-resistant foliage. Because it is liquid and fast-absorbing, it supports new shoots within days of application.
- Apply fertiliser within a week of pruning.
- Repeat every 4โ6 weeks through spring and summer.
- Water well after feeding to help nutrients move into the root zone.
Pruning Mistakes to Avoid
The most common errors with Viburnum pruning are cutting too hard or failing to fertilise afterwards. Harsh cuts into old wood take months to recover and often leave gaps. Light, regular trims combined with balanced fertiliser produce far better results than one heavy cut per year.
For reliable results, pair each prune with Complete Grow All Purpose Liquid NPK 20-20-20. This feeding routine keeps hedges vigorous, colourful, and resistant to stress.
