Creating a New Lawn From Seed

Growing a lawn from seed is an affordable and rewarding way to achieve a lush, healthy garden. The key to success lies in timing, preparation, and ongoing care.

Grass seed can be bought at any time of the year and stored until required, where-as turf has a short shelf life and should be laid as quickly as possible.

When to Sow Your Lawn

The best times to sow a new lawn are mid-spring and early autumn. Soil temperatures are moderate, and moisture levels are stable — perfect for germination.
  • Seeds typically germinate within 7–10 days under ideal conditions.
  • Avoid frost, extreme heat, or drought when sowing.

Choosing the Right Seed Mixture

Different lawns have different needs. Choose a blend based on how your lawn will be used:
Use Case Recommended Blend Notes
High-traffic / family use Perennial ryegrass, tall fescue Durable and fast-growing
Ornamental / low use Chewings fescue, slender fescue Fine texture, elegant appearance
Shaded areas Shade-tolerant fescue blends Thrives under low light

Preparing the Seed Bed

  1. Clear the area of all weeds and debris.
  2. Loosen soil to 15–20 cm deep using a fork or rotovator.
  3. Add compost or manure and mix well.
  4. Allow the soil to settle, then remove any new weeds.
  5. Rake, level, and firm the surface evenly.
  6. Apply a general-purpose fertiliser before sowing.

Sowing & Watering

For even growth and coverage, sow at approximately 35–50 g/m².

  • Sow in two directions — lengthways, then widthways.
  • Lightly rake to cover most of the seeds with soil.
  • Keep soil consistently moist but avoid overwatering.

Aftercare & First Mowing

  • Compact gently once seedlings reach about 3 inches tall.
  • First mow when grass reaches 7–8 cm, trimming only one-third of its height.
  • Avoid heavy use during the first season.
  • Protect from birds using netting or reflective deterrents.

Frequently Asked Questions

  • How long until I can walk on my new lawn?

    • Wait until the grass has been mown several times and feels firm underfoot — usually 6–8 weeks after germination.
  • What if my lawn is patchy?

    • Reseed thin areas, water consistently, and protect from birds for even regrowth.
