How to Grow Your Own Lawn for $20: Easy, Budget-Friendly DIY for Small Gardens

Spring is here, and there’s no better time to start growing your own lawn! Early spring is ideal (before the weather gets too hot) so your grass has time to establish strong roots and grow lush and green. I recently transformed my ~20m² patch into a thriving lawn for just $20, and I’m sharing how you can do it too.

Why Growing Your Own Lawn is Perfect for Urban Gardens

Creating a lawn in a small urban space is easier – and FAR cheaper – than you might think. Beyond looking beautiful, a lawn provides:

  • A soft, pet or child friendly play area (Odie approves!).
  • A natural cooling effect for hot Aussie days.
  • A sense of calm and green space in the city.

With the right approach, even a compact courtyard or balcony garden can be transformed into a vibrant green patch.

🌱Seeds vs Turf: Why Starting from Seed is Surprisingly Easy

Laying turf offers instant results, but it’s expensive and heavy. I once tried this for the exact same patch, and it was horrible, back breaking and wallet destroying work (~$800). Never again.

For a small space, growing from seed is easier, cheaper, and incredibly satisfying. I used the Garden Basics 1kg Tough & Hardy Lawn Seed ($10) from Bunnings, which is designed for fast establishment and resilience in urban conditions.

Starting from seed gives you control over the grass type and allows it to adapt naturally to your microclimate. With a little patience, you’ll have a soft, durable lawn without breaking the bank.

The Products That Made It Easy

To give my seeds the best start, I also used Munns Professional 2.5kg Instant Turf and Seed Starter Fertiliser ($12). It combines fertiliser and a wetting agent to promote germination and healthy root development – essential for a thriving lawn.

🌿Step-by-Step Guide to Growing Your Lawn

  1. Prepare the Soil – Remove weeds, stones and other debris. Loosen soil with a rake or fork.
  2. Sow the Seeds – Spread evenly. Some instructions say to use a seed spreader but I say use the seed spreaders God gave you – aka your hands.
  3. Add Fertiliser – Mix Munns Starter Fertiliser with the seeds for even growth (don’t overthink this. I literally just grabbed a handful of each for every sprinkle).
  4. Water Regularly – Keep soil moist until seeds germinate. Water early in the morning for best results – if it’s a hot day, another drink before evening falls.
  5. Keep the faith! – Remain patient. It might grow all wispy like and in clumps and look horrible to begin with, but trust me – it will come good. Keep scrolling for the photos if you don’t believe me…
  6. Mow Carefully – Once established, mow regularly, but never cut more than a third of the grass height at a time. Mow at a different angle each time to encourage the blades to grow strong.

Why Early Spring is the Perfect Time

Starting your lawn now gives it a full growing season before the summer heat sets in. Grass establishes better in mild temperatures, and watering is easier than in the peak of summer. By the time December rolls around, you’ll have a lush, green oasis ready for relaxing, Christmas hosting, and Odie-approved zoomies.

Final Thoughts

Growing your own lawn in an urban garden is easier, cheaper, and more rewarding than many people think. With the right seed, a good starter fertiliser, and a little patience, you can create a soft, green space in just a few weeks. For ~20m², I spent around $20 – and the joy of stepping onto fresh, self-grown grass is priceless. And it being Odie’s new favourite napping spot is the cherry on top!

Pretty stoked with how this grass turned out – lush but soft underfoot, and a lovely green. Looks like we have Odie’s paw of approval too!
