Best Fertiliser for Murraya Paniculata (Orange Jasmine)

Murraya paniculata, also known as orange jasmine, mock orange, or simply the Murraya hedge, is one of Australia’s most popular evergreen hedging plants. It is valued for its dense glossy leaves, fragrant white flowers, and fast growth, making it a go-to choice for creating privacy screens and decorative garden borders.

To maintain lush foliage and heavy flowering, Murraya requires consistent feeding. The plant responds best to a balanced NPK fertiliser that delivers:

Nitrogen (N): Fuels strong green leaf growth for dense hedges.
Phosphorus (P): Promotes robust root systems and flower production.
Potassium (K): Supports continual blooming and disease resistance.

Common problems if under-fertilised:

Yellow leaves → usually nitrogen or iron deficiency.
Thin, sparse growth → lack of pruning and poor feeding.
Reduced flowering → imbalance in phosphorus and potassium supply.

Quick Care Snapshot:

Soil: Free-draining, enriched with organic matter.
Sunlight: Full sun to part shade.
Watering: Consistent during establishment, drought-tolerant once mature.
Fertiliser: Balanced NPK liquid or soluble powder applied every 6–8 weeks during the growing season.

How to Fertilise Murraya Paniculata

A structured fertiliser routine is essential to keep Murraya hedges dense and flowering year-round. Here’s the recommended schedule:

Seasonal Feeding

Spring: Heavy feed to encourage vigorous new growth and buds.
Summer: Balanced fertiliser every 6–8 weeks to support repeat flowering.
Autumn: Moderate feeding to strengthen before winter.
Winter: Minimal or no fertiliser as growth slows.

Best Fertiliser Types

Liquid NPK fertilisers: Fast-acting, ideal for flowering boosts.
Powder soluble NPK fertilisers: Cost-effective for large hedges, easy to mix in water.
Calcium & Magnesium supplements: Prevent yellow leaves and improve resilience.

Application Tips

Use 1–2ml liquid fertiliser per litre of water.
Apply evenly at the hedge base, soaking into roots.
Water well after feeding to avoid fertiliser burn.
For large hedges, use a sprayer for efficiency.

Mistakes to Avoid

Over-fertilising, which scorches roots.
Using lawn fertiliser (imbalanced nutrients for shrubs).
Applying in extreme heat, which stresses plants.

Murraya Fertiliser Problems & FAQs

Common Issues

Yellow leaves: Iron or nitrogen deficiency. Fix with balanced NPK + trace elements.
Sparse base growth: Prune regularly and fertilise after cutting.
Few flowers: Use higher phosphorus and potassium before flowering season.
