How Tall Do Lilly Pillies Grow?
Lilly Pilly (Syzygium species) is an adaptable Australian hedge plant that comes in many different varieties. Depending on the cultivar, Lilly Pilly can grow anywhere from 1 metre to over 10 metres tall. This makes it suitable for both compact hedges and tall privacy screens.
Typical Heights by Variety
- Dwarf Lilly Pilly: 1โ2m, ideal for low borders and small hedges.
- Medium varieties: 3โ5m, common in suburban gardens for privacy screening.
- Tall screening types: 6โ10m, fast-growing for large hedges and boundary planting.
Most commonly planted varieties used for hedging in Australia grow to 3โ5m if left unpruned, but with regular trimming, they can easily be maintained at your desired height.
Controlling the Height of Lilly Pilly Hedges
Lilly Pilly grows quickly, but you can control its ultimate height with pruning and care. Hereโs how:
Pruning
- Trim lightly 3โ4 times per year to maintain a set hedge height.
- Hard prune in early spring if hedges become too tall or woody.
- Pruning encourages thicker growth at the base, preventing tall, leggy plants.
Spacing & Variety Choice
- Choose a dwarf variety if you want a low-maintenance hedge under 2m.
- For privacy screens, select fast-growing medium or tall types that can reach 5โ10m.
- Proper spacing (50โ100cm) ensures plants grow evenly and donโt outcompete each other for light.
Feeding for Controlled Growth
Feeding Lilly Pilly with CompleteGrow All Purpose NPK 20-20-20 keeps growth strong but manageable. Fertilise every 6โ8 weeks in-ground, or every 2โ4 weeks for potted plants, to maintain healthy height without stressing the plant.
