Why Grass Seed Is Worth Considering
Laying turf is the fastest way to a new lawn, but it costs $8–15 per square metre — for a 200m² lawn, that is $1,600–3,000 just in turf. Grass seed costs a fraction of that: $30–80 will cover the same area. The trade-off is time — seed takes 3–6 weeks to establish versus instant results with turf. For overseeding thin patches, repairing damage, or establishing a new lawn on a budget, seed is the practical choice. The key is choosing the right variety for Brisbane's subtropical climate.
Best Grass Seed Varieties for Brisbane
| Variety | Sun Needs | Drought Tolerance | Wear Tolerance | Best Use |
|---|---|---|---|---|
| Couch (Wintergreen) | Full sun (8+ hours) | Excellent | Excellent | Full-sun lawns, sports areas, budget option |
| Kikuyu (Whittet) | Full sun to light shade | Very good | Excellent | Large blocks, quick coverage, slopes |
| Tall Fescue (blend) | Part shade to full sun | Good | Good | Shaded lawns, cool-season oversowing |
| Perennial Ryegrass | Full sun to part shade | Low | Good | Winter oversowing for colour |
Warning
You cannot buy Buffalo grass as seed — it must be laid as turf or planted from runners. If you want a Buffalo lawn (Sir Walter, Sapphire, Palmetto), turf is your only option. This is because Buffalo varieties are sterile hybrids propagated vegetatively.
How to Sow Grass Seed in Brisbane
- 1
Choose the right time
Sow warm-season grasses (Couch, Kikuyu) from mid-October to January when soil temperatures are consistently above 18°C. Sow cool-season grasses (Tall Fescue, Ryegrass) from March to May.
- 2
Prepare the soil
Remove weeds, rake the surface to a fine tilth, and level any bumps. For new lawns, add a 25–50mm layer of turf underlay or sandy loam. Lightly compact with a roller or by walking over the area.
- 3
Spread seed evenly
Use a broadcast spreader for large areas or hand-spread for small patches. Apply at the rate specified on the packet (usually 30–50g per m² for new lawns, 15–25g for overseeding). Spread half the seed walking north-south and the other half walking east-west for even coverage.
- 4
Lightly cover and firm
Rake seed in lightly (no more than 5mm deep — grass seed needs light to germinate). Roll or firm the surface gently so seeds have good soil contact.
- 5
Water consistently
This is the critical step. Keep the soil consistently moist (not waterlogged) until germination — that means light watering 2–3 times per day for the first 2–3 weeks. A single day of drying out can kill germinating seeds. Reduce to daily then every-other-day as grass establishes.
- 6
First mow at 50mm
Wait until grass reaches about 50–60mm before the first mow. Set your mower high and remove no more than one-third. Gradually lower mowing height over subsequent mows.
Pro Tip
For patching bare spots in an existing lawn, rough up the soil surface with a rake, scatter seed, top with a thin layer of lawn seed raising mix (not regular soil), and keep moist. The seed raising mix holds moisture better than bare soil and dramatically improves germination rates.
