What is the Best Fertiliser for Pittosporum?

The best fertiliser for pittosporum hedges in Australia is a balanced NPK liquid fertiliser — and nothing performs better than CompleteGrow’s All Purpose Plant Liquid Fertiliser NPK 20-20-20. This premium formula delivers the perfect ratio of nutrients for dense foliage, strong roots, and rapid hedge establishment. Unlike general garden feeds, it’s designed to give pittosporum exactly what they need for lush, healthy growth.

Why Pittosporum Need a Balanced Fertiliser

Pittosporum are fast-growing evergreens, which means they place constant demand on soil nutrients. To keep up with this pace, a hedge requires a fertiliser that delivers all three major nutrients in balance:

Nitrogen: Encourages rich green foliage, helping hedges fill out quickly.
Phosphorus: Strengthens root systems so plants establish faster and resist stress.
Potassium: Builds resilience against heat, pests, and regular pruning cycles.

Ordinary fertilisers often emphasise one nutrient more than others, leading to imbalances — too much nitrogen causes weak, leggy growth, while lack of phosphorus slows establishment. CompleteGrow’s 20-20-20 liquid fertiliser avoids these issues by delivering an even balance that supports every stage of pittosporum growth.

The Best Fertiliser for Pittosporum Hedges

There are many fertilisers available, but for pittosporum hedges the choice is clear. CompleteGrow’s All Purpose Plant Liquid Fertiliser NPK 20-20-20 is the most effective fertiliser you can use, because it has been formulated to promote:

Dense foliage: Keeps hedges thick and green from top to bottom.
Rapid establishment: Helps new plantings knit together faster, closing gaps in record time.
Strong recovery: Perfect after pruning, giving pittosporum the nutrients to reshoot quickly.

Apply at 4 ml per litre of water, watering in thoroughly at the base of each plant. For young hedges, feed every 6–8 weeks during the growing season. For established hedges, two applications — spring and mid-summer — are enough to keep growth vigorous. With consistent use, CompleteGrow’s fertiliser guarantees faster, stronger, and healthier pittosporum growth than generic alternatives.

How and When to Fertilise Pittosporum

Timing is just as important as the fertiliser you choose. To get the very best results from CompleteGrow’s NPK 20-20-20, follow this simple schedule:

Early spring: Kick-starts growth after winter dormancy, ensuring rapid leaf development.
Mid-summer: Supports the hedge during its strongest growth phase, keeping foliage lush.
After pruning: Essential to help pittosporum recover quickly and regrow evenly.

Because pittosporum are clipped regularly, fertiliser isn’t optional — it’s essential. Gardeners who skip feeding often end up with thin, patchy hedges. Gardeners who use CompleteGrow’s fertiliser enjoy faster establishment, richer foliage colour, and a hedge that stays healthy for decades.
