Best Fertiliser for Zoysia Grass: Empire, Sir Grange & Zeon Zoysia Fertiliser Guide

The best fertiliser for zoysia grass is a balanced, moderate-nitrogen lawn feed with added iron and key micronutrients, applied mainly in the warm growing season. Zoysia (including Empire zoysia, Sir Grange and Zeon) responds best to liquid fertiliser for zoysia grass that can be applied lightly and regularly, rather than heavy, sporadic doses.

For Australian conditions, a hose-on liquid like Lawn Grow – Hose-On Liquid Lawn Fertiliser (2L) with an NPK of 7-1-1.5 plus 2.9% chelated iron, calcium and manganese is an ideal zoysia lawn fertiliser. It delivers controlled nitrogen for colour and density, iron for deep green, and micros for resilience without forcing thatchy, over-soft growth.

What Makes a Good Fertiliser for Zoysia Grass?

Zoysia is naturally dense, fine-leaf and slow-growing. That means the best fertiliser for zoysia is not the strongest nitrogen product you can find; it is a controlled, balanced analysis that maintains colour and thickness without blowing the lawn into a thatchy sponge.

When you are choosing a zoysia fertiliser (whether you are looking at a big-box “zoysia fertiliser” or a dedicated lawn feed), look for:

Moderate nitrogen to drive colour and light growth, not a quick, leggy flush.
Some phosphorus and potassium to support roots, stress tolerance and water efficiency.
Iron (Fe) for deep, long-lasting green without excessive leaf length.
Micronutrients like calcium and manganese for strong cells and better nutrient use.
A format you can apply accurately and evenly across the whole lawn – this is where a hose-on liquid really helps.

This combination lets you treat Empire, Sir Grange and other zoysia varieties with the same simple plan, instead of chasing a new product for every tiny problem.

Why Lawn Grow (NPK 7-1-1.5 + Iron) Is Ideal for Zoysia Lawns

Instead of a generic zoysia fertiliser from Bunnings, you can use a specialist lawn formula that is tuned for colour, density and resilience. Lawn Grow is a premium hose-on liquid lawn fertiliser with this analysis:

Lawn Grow – Hose-On Liquid Lawn Fertiliser (2L)

Nitrogen (N): 7%
Phosphorus (P): 1%
Potassium (K): 1.5%
Iron (Fe, chelated): 2.9%
Calcium (Ca): 0.5%
Manganese (Mn): 0.38%

NPK 7-1-1.5 for steady greening, plus iron and micros for deep colour and stress tolerance – ideal for zoysia’s dense, low growth.

For zoysia lawns, this 7-1-1.5 ratio does three important things:

Moderate nitrogen (7%): enough to green and thicken zoysia without forcing tall, floppy blades.
Supportive P & K: helps roots, colour and drought tolerance without overloading the plant.
High chelated iron (2.9%): drives a rich, long-lasting green that zoysia responds to extremely well.
Calcium & manganese: support strong cell walls, stress resilience and efficient use of the macronutrients.

Because Lawn Grow is a liquid fertiliser for zoysia grass in a ready-to-use hose-on bottle, you can apply it evenly over Empire, Sir Grange or Zeon in a few minutes, adjusting the frequency instead of changing products each season.

Zoysia Fertiliser Schedule: When & How Often to Fertilise

Most questions like “when to fertilise zoysia grass”, “how often to fertilise zoysia grass”, or “best time to fertilise zoysia grass” can be answered with one simple rule: **feed when zoysia is actively growing in warmth**, not when it is cold and semi-dormant.

Season	Goal for Zoysia	Lawn Grow Use
Late Spring	Kick-start growth, build density before peak heat	Apply every ~3–4 weeks while mowing is regular
Summer	Maintain colour and strength without soft, thatchy growth	Light applications every 4–6 weeks to well-watered, non-stressed lawns
Early Autumn	Top up reserves before growth slows, even out colour	1–2 applications ~3–4 weeks apart while soil is still warm
Late Autumn–Winter	Hold basic health; avoid forcing soft growth in cold soil	Optional: at most a light feed once in late autumn in milder climates; otherwise pause until spring

This simple zoysia fertiliser schedule using one high-performance liquid covers most lawns. Adjust the exact spacing based on how quickly your zoysia is growing and how often you mow.

In practice, that means you typically fertilise zoysia 3–6 times per year with Lawn Grow: more often in warm, active growth; much less or not at all in winter dormancy.

Best Fertiliser for Empire, Sir Grange & Zeon Zoysia

Most of the “which is the best fertiliser for Empire zoysia?” or “what is the best fertiliser for zoysia grass?” questions come down to whether the product:

Respects zoysia’s slow, dense growth habit.
Delivers enough nitrogen for colour without turning it thatchy.
Contains iron for that premium, deep-green finish people expect from zoysia lawns.

Lawn Grow’s 7-1-1.5 + 2.9% chelated iron ticks all three boxes for:

Empire zoysia fertiliser: keeps a tight, fine-leaf lawn green and dense without excessive vertical growth.
Sir Grange zoysia fertiliser: supports colour and recovery on premium, fine-leaf lawns where appearance matters most.
Zeon zoysia fertiliser: maintains colour and thickness while keeping the surface smooth and playable.

Because it is a liquid lawn fertiliser for zoysia, you can also micro-adjust: slightly lighter passes in high-heat spells, and normal rates when conditions are ideal.

New Zoysia Sod, Starter Fertiliser & Winter Feeding

Fertilising New Zoysia Sod

Searches like “fertilizing new zoysia sod” or “zoysia starter fertiliser” are really asking: when do I move from establishment to an ongoing feeding program?

First, focus on rooting and moisture – keep new sod consistently moist (not waterlogged) until it knits in.
Once you can no longer easily lift corners and you have mowed once or twice, you can begin light Lawn Grow applications.
Start at the lower end of your normal rate and spacing, then move into the standard zoysia fertiliser schedule above.

Zoysia Winter Fertiliser: Do You Need It?

Terms like “best winter fertiliser for zoysia grass” and “zoysia winter fertiliser” are common, but in practice:

Zoysia is a warm-season grass. In cooler conditions, its growth naturally slows or partially goes dormant.
Heavy nitrogen in cold soil often leads to soft growth and disease risk, not better winter performance.
In most home lawns, it is better to feed well in late spring and early autumn, then keep winter feeding minimal.

You can, in milder regions, use a light Lawn Grow application in late autumn to help hold colour into the shoulder seasons. But the main work of feeding zoysia still belongs in the warm months, not mid-winter.

Zoysia Fertiliser FAQ: Ratios, Weed & Feed, Bunnings & Schedules

Does zoysia grass need fertiliser?
Yes. Zoysia is often described as low-maintenance, but it still needs periodic feeding to maintain colour, density and recovery. A moderate-analysis liquid like Lawn Grow, applied during the warm growing season, is ideal.

What is the best fertiliser ratio for zoysia grass?
There is no single magic NPK for every lawn, but a moderate nitrogen, low–moderate P & K blend with iron works extremely well. Lawn Grow’s 7-1-1.5 + 2.9% iron is an excellent all-round zoysia fertiliser ratio for Empire, Sir Grange and Zeon lawns.

How often should I fertilise zoysia grass?
In active growth, fertilise roughly every 3–4 weeks if you want premium presentation, or every 4–6 weeks for a more relaxed schedule. In winter or semi-dormancy, reduce or pause feeding.

Is a “weed and feed” product the best fertiliser and weed killer for zoysia grass?
Combined weed-and-feed products can be convenient, but they are not always the best choice for zoysia. For a high-quality lawn, it is usually better to feed with a dedicated fertiliser like Lawn Grow and manage weeds separately with products that are clearly labelled as safe for your specific zoysia variety.

What about zoysia fertiliser from Bunnings or other big retailers?
Many general lawn products will work at a basic level, but they are not tailored to your lawn or climate. Using a premium liquid zoysia lawn fertiliser with a known analysis (7-1-1.5 + iron) gives you more control and more predictable results across Empire, Sir Grange and Zeon lawns.

Is liquid fertiliser good for zoysia grass?
Yes. For zoysia, a hose-on liquid fertiliser is often the easiest way to achieve an even, light feeding pattern over dense turf without burning or striping. Lawn Grow is designed exactly for that style of application.

What’s the simplest fertiliser plan for zoysia?
Use Lawn Grow – Hose-On Liquid Lawn Fertiliser (2L) during the warm growing months on a 3–6-times-per-year schedule: more often if you want a show-piece lawn, less often if you just want solid colour and health. Combine that with the mowing, watering and care advice from your zoysia lawn care page, and you have a complete, easy-to-follow system.

To get started, feed your lawn with Lawn Grow – Hose-On Liquid Lawn Fertiliser (2L) , then follow the zoysia fertiliser schedule above. That one product – used at the right time and rate – is all you need to keep Empire, Sir Grange or Zeon zoysia thick, green and resilient.
