Best Fertiliser for Lilly Pilly Hedges

Lilly Pilly (Syzygium species) is one of Australia’s favourite hedge plants, known for its glossy leaves, colourful new growth, and fast-growing, dense form. To keep hedges healthy and vibrant, the right fertiliser makes all the difference. Whether planted in the ground or grown in pots, Lilly Pilly benefits from regular feeding with a balanced CompleteGrow fertiliser.

In-Ground Lilly Pilly Hedges

Use CompleteGrow All Purpose NPK 20-20-20 for dense foliage, strong roots, and colourful new growth. Apply every 6–8 weeks from spring through autumn. Water in well after feeding to help nutrients reach the root zone and prevent fertiliser burn.

Potted Lilly Pilly

Feed with CompleteGrow All Purpose NPK 20-20-20 Liquid every 2–4 weeks. Potted plants deplete nutrients quickly and respond best to liquid feeding, which delivers fast uptake and visible improvement in leaf colour and growth.

How to Fertilise Lilly Pilly Hedges

A consistent feeding schedule keeps Lilly Pilly hedges thick, colourful, and pest-resistant. Follow these seasonal guidelines:

Seasonal Feeding

Spring: Apply a full feed to drive new growth after winter dormancy.
Summer: Fertilise every 6–8 weeks to maintain vibrant red flushes and dense foliage.
Autumn: Apply a lighter feed to strengthen roots before cooler weather.
Winter: Minimal fertiliser is needed as growth slows, but evergreen foliage will hold colour with light feeding.

Application Tips

Always water deeply after fertilising to carry nutrients to the roots.
Feed immediately after pruning to encourage quick regrowth and hedge thickening.
Mulch around the base of in-ground plants to conserve moisture and stabilise nutrients.
Halve the dosage for potted Lilly Pilly to avoid root burn.
