Instant Turf vs Seed: How to Give Your Lawn Its Best Start

Believe it or not, there are many ways to establish a new lawn. When you’re dreaming of a thriving, green patch of grass, the first major decision you’ll face is the method: do you take the long road of sowing lawn seeds from scratch, or opt for the safer route of installing instant turf?

While the quickest and easiest way is to install solid turf, some people choose to grow a lawn from seed due to budget restrictions. Both methods have their place, but the decision between an instant turf vs seed comes down to a trade-off between upfront cost, time, effort and the certainty of your desired results. This guide breaks down the key differences to help you decide which path will give your new lawn its best start.

The Case for Growing a Lawn from Seed

For many, the primary appeal of a seeded lawn is the price tag. It’s generally seen as a more affordable option. But before you bank on how much you can potentially save, make sure you’re comparing ‘apples with apples’ and take into account the extra inputs required to get a good result from seeding.

A Cost-Effective Option for a Tight Budget?

There's no doubt that lawn seed is cheaper at the checkout compared to buying enough instant turf rolls or slabs to cover the same area. But keep in mind that there are hidden costs that can run higher than with professionally pre-grown turf:

• Water costs (utility bills): You’ll generally need to irrigate more and for longer to ensure healthy root system establishment.
• Labour costs: Laying from seed requires significant time and effort, preparing the site and maintaining it for the first few months. Even if you DIY, keep in mind the demands on your time.
• Fertiliser: You’ll want to use a starter fertiliser and give follow-up feeds with a nitrogen-based product every 6-10 weeks. Conversely, instant lawn generally needs only one application of starter fertiliser upon installation, and doesn’t require as frequent top-ups.

The Downsides of a Seeded Lawn vs Instant Turf

The process of growing a lawn from seed demands patience and hard work, and there’s always a significant risk of failure.

The Long Wait for a Lush Lawn

This is the biggest drawback. Seeding a new lawn can be an exercise in patience. After sowing seeds, you must wait for the germinating seed to sprout. It can take six to eight weeks (or even longer) before you see full, even coverage. A mature, usable lawn can be many months away.

It’s a Labour-Intensive Process

Achieving an acceptable result with seed requires meticulous preparation. You need to prepare the soil, ensuring it’s a fine consistency free of lumps, sow the seed, and then often rake for a second time. The seed must be spread evenly across the site to avoid a lumpy, uneven surface.

It’s important to factor in the time and potential labour costs involved in seeding a new lawn, especially for larger sites.

Vulnerability to Weeds and Weather

With a seeded lawn, the bare soil is exposed, and with high moisture and nutrient levels, weed germination is inevitable. These weeds compete with your new grass for resources. The young seedlings are also extremely vulnerable. A few days of extreme heat, unexpected heavy rain, or hungry birds can ruin the entire project, forcing you to start over.

On the other hand, pre-grown grass (instant turf) – if purchased from a reputable supplier – should generally be weed-free and weed-resistant, especially if the topsoil is prepared properly. If installed correctly and adequately watered and cared for during the vital first few weeks, herbicide applications will likely not be required.

Patchy Areas are Common

Even with perfect preparation, achieving even coverage with seed is notoriously difficult. It’s common to end up with a mix of thick clumps and bare or thinning areas that require repeat applications and a lot of ongoing effort to fill in.

The Advantages of Choosing Instant Turf

For homeowners who value certainty, speed, and a high-quality finish, the grass seed vs turf question is an easy one. Laying new turf slabs eliminates the risks and delays of seeding and gives you every chance of a lawn that will thrive for decades to come.

A Green Lawn in a Day

Instant turf is known as instant turf for a reason! It’s quick to lay down and has an immediate visual impact, transforming your yard from bare soil to a lush green lawn in a matter of hours. The turf arrives ready to lay, and there's no long wait for it to grow.

Guaranteed Even Coverage and a Weed-Free Start

Instant turf is grown by professionals on dedicated farms. It arrives as a dense, mature, and generally weed-free product. When laid correctly, you get a perfectly uniform lawn with no patchy areas from day one.

More Durable and Resilient

Because instant turf is already a mature plant with an established root system, it is far more resilient than delicate seedlings. It can handle a wider range of weather conditions during its establishment period and is less susceptible to pests and diseases. It will be able to establish deeper, stronger roots more quickly, making it more wear and drought tolerant.

Usable Sooner

While you need to avoid heavy foot traffic for the first few weeks, an instant lawn is generally robust enough for light use much sooner than a seeded lawn. The greatest benefit of instant turf is how quickly it will establish, making it ready for family life faster.

Laying Turf vs Seed: A Note on Available Varieties

It’s a common misconception that choosing lawn seed gives you more options. While the seed market has many blends, this apparent variety comes with a major catch: many of Australia’s best and most popular premium lawn types simply cannot be grown from seed. Elite varieties like Sir Walter DNA Certified Buffalo and TifTuf Bermuda are ‘male sterile’, meaning their seeds are infertile.

These advanced grass types are professionally propagated from cuttings to create the instant turf you buy. This process guarantees you receive an exact genetic clone of the parent plant, locking in all the desirable traits, like superior drought and shade tolerance that you’re paying for.

Furthermore, the choice of grass type can have a big impact on family health. Grasses that rely on producing viable seed also produce large amounts of pollen, a major trigger for hay fever and allergies. In contrast, sterile varieties like Sir Walter produce very few seed heads, making them a fantastic low-allergenic choice for family backyards.

Getting the Best Results

Regardless of your chosen method, a successful lawn requires proper preparation, correct technique and essential lawn care during the first few weeks.

Tips for Laying Turf

1. Prepare the Soil: Ensure you have at least 100mm of quality turf underlay on your prepared soil.
2. Lay on the Day: Aim to lay your turf the same day it arrives.
3. Install in a Brickwork Fashion: Stagger the joints of the turf slabs like bricks to create a seamless finish.
4. Water Immediately: As soon as you lay a section, water it. A deep soaking is critical for the newly laid turf to avoid the grass drying out.

The Verdict: Which is the Better Option for You?

Choose Lawn Seed if: You have a very tight budget and have more spare time than spare money. You enjoy the process of nurturing growth from scratch. You understand the risks and accept that when you seed a project, there is no guarantee that you will get the desired results.

Choose Instant Turf if: You value your time and want a guaranteed, high-quality result. You want a usable, healthy lawn quickly, for kids, pets, or entertaining. An instant lawn landscape solution will guarantee you get a result from your time and cost investment. In the long run, the certainty and superior finish of instant lawn often make it the more valuable choice.
