How to Prune Lilly Pilly
Lilly Pilly (Syzygium species) is a fast-growing hedge plant, but without pruning it can become tall, leggy, or uneven. Pruning not only controls height and shape, it also encourages dense foliage from the base, resulting in a fuller, more attractive hedge. Done correctly, Lilly Pilly responds quickly with lush regrowth.
Benefits of Regular Pruning
- Keeps the hedge dense and uniform.
- Encourages fresh flushes of colourful new growth.
- Prevents hedges from becoming woody or sparse at the base.
- Helps maintain the hedge at your preferred height and width.
Step-by-Step Guide to Pruning Lilly Pilly
Pruning is simple but timing and technique matter. Here’s how to prune for best results:
1. Choose the Right Time
- Spring: Major prune after the first flush of growth to encourage branching.
- Summer: Light trims every 6–8 weeks to maintain shape and density.
- Autumn: A tidy-up before winter to strengthen plants.
- Winter: Only minimal trimming, as growth slows.
2. Pruning Technique
- Use clean, sharp hedge shears or trimmers for even cuts.
- Trim hedge sides slightly narrower at the top to allow sunlight to reach lower foliage.
- Never remove more than one-third of growth at once, except in a hard rejuvenation prune.
3. Aftercare
- Water deeply after pruning to reduce stress.
- Feed with CompleteGrow NPK 20-20-20 immediately after trimming to encourage fast regrowth.
- Mulch around the base to retain moisture and improve soil health.
