Just laid new turf? Here's how to get it established properly.

The first 6 weeks after laying new turf decide whether you end up with a dense, healthy lawn or a patchy, struggling one. Most people do the hard work of laying it correctly and then underestimate what comes next. The turf looks green, it feels solid, and it is easy to assume the job is done. It is not. The root system is sitting on top of the soil with almost no depth. Until those roots push down and anchor into the ground below, your new lawn is fragile and the decisions you make in this window matter more than anything else you will do for it.

What is actually happening under the surface

When turf arrives on a pallet it has been cut from a growing field. The root system is short, the soil layer is thin, and the grass is under stress from being lifted, rolled, and transported. Your job in the first weeks is not to push growth it is to create the conditions that allow the roots to reach down into your soil base and establish contact.

Until that happens, the turf is entirely dependent on what you give it from the surface. It cannot draw water or nutrients from depth because it has no roots there yet. This is why new turf fails not because of poor quality grass, but because the establishment window is mismanaged.

Watering: the only job that matters in week 1 and 2

Water daily for the first 2 weeks, without fail. In cooler months like June and July, once a day is sufficient. In warmer months, twice a day may be needed. The goal is to keep the soil beneath the turf consistently moist not waterlogged, but never dry.

Pay close attention to the edges and corners of each slab. These dry out first and will turn yellow before the centre of the roll shows any signs of stress. Yellow edges are a warning that the turf is not getting enough water. Act on it immediately.

From week 3, move to watering every second day. From week 4 onwards, reduce to 2 to 3 times per week. You are training the roots to chase water down into the soil profile deep, less frequent watering encourages deeper root growth. Shallow daily watering after the first fortnight does the opposite.

When to mow for the first time

Do not mow until the turf has rooted into the soil below. Test it by trying to lift a corner of a roll if it lifts easily, it is not ready. If it holds firm, you can mow. This is usually around week 4, depending on the time of year and how well the establishment has progressed. Set the mower high on the first cut remove only the top of the leaf. Never take more than one third of the leaf height in a single mow.

Keep foot traffic to a minimum for the first 4 to 5 weeks. Every time someone walks across unestablished turf it compresses the soil contact and slows root development.

The product that makes the biggest difference at establishment

Most people wait until the lawn looks established before applying any products. This is the wrong approach. The establishment phase is exactly when the root zone needs support before stress sets in, not after.

Vital is a root stimulator containing natural auxins and Vitamin B1. Applied at 100ml per 100m2 to the soil layer and watered in immediately, it stimulates the root development that drives successful establishment. This is the single most important product for new turf in the first weeks.

Soak is equally important if your base soil has any hydrophobic tendency and in many Australian backyards, particularly in sandy or clay-heavy soils, it does. Hydrophobic soil repels water at the surface, meaning your daily watering runs off rather than penetrating to where the roots are trying to grow. Soak at 200ml per 100m2 breaks that barrier and ensures water reaches the root zone. Apply to the soil layer and water in immediately.

Base conditions the soil biology using Tasmanian Bull Kelp. Applied at 120ml per 100m2 and watered in immediately, it builds the soil environment that new roots are growing into. A biologically active soil establishes turf faster and more evenly than a depleted one.

These 3 products work together as the soil layer of the Turf & Surf program. For new turf, apply them together in the first week, water in immediately, and repeat monthly through the establishment period.

When to start fertilising

Hold off on fertiliser for the first 6 weeks. New turf does not need a feed push it needs root establishment first. Applying a nitrogen-heavy fertiliser too early can stress the plant and burn the shallow root system. Once the turf has rooted firmly and you have completed your first mow, introduce Surge at 200ml per 100m2 as a foliar spray, allowing 2 hours dwell time before watering in.

Vivid at 200ml per 100m2 can be introduced at the same time to bring colour into the leaf layer. Apply to the leaf surface and water in after 2 hours.

Complete the program

Once your new turf is established, the Turf & Surf 5-step program gives you the full monthly routine to keep it performing year round. Every product, every layer, every month.

Frequently asked questions

My new turf is turning yellow at the edges. What do I do?
Yellow edges are the first sign of insufficient watering. The edges and corners of each slab dry out before the centre. Increase watering frequency immediately and make sure the edges are getting as much water as the rest of the lawn.

Can I apply Turf & Surf products straight after laying?
Yes — the soil layer products (Soak, Vital, Base) can be applied in the first week and are beneficial for establishment. Hold off on Surge and Vivid until after the first mow at around week 6.

How long does new turf take to fully establish?
Surface rooting happens in 3 to 4 weeks. Full deep establishment — where roots have grown well into the soil profile — takes closer to 3 months. Treat it carefully for the first 6 weeks and it will reward you for years.

Should I fertilise before laying turf?
A light application of Base to the prepared soil bed before laying is beneficial — it conditions the soil biology that the new roots will grow into. Avoid heavy nitrogen fertilisers in the base preparation as they can burn new roots on contact.

Can I lay turf in winter in Australia?
Yes, though establishment is slower in cooler months because warm-season grasses like couch, kikuyu, and buffalo are not actively growing. The soil layer program (Soak, Vital, Base) is especially important in winter establishment as it supports root development during a period when the plant's natural growth drive is reduced. Be patient — the turf will establish, it just takes longer.
