Organic blend

Contains composted organic materials as well as slow release fertiliser

Does not contain any animal waste or by-products

Iron for greening

Includes a quick release iron that helps green lawns up rapidly

Controlled feeding

Slow release of nutrients eliminates waste through run-off and leaching and prevents burning

Wetting agent

Assists moisture to soak into the soil and improves nutrient uptake through roots

No surge growth after application

Traditional lawn foods release or 'dump' most of their nutrients within a couple of weeks of application, causing a rapid surge in growth that quickly drops off again as the food supply diminishes. Scotts Lawn Builder™ uses patented time-release technology to ensure nutrients are released slowly and continuously over a three month period

Australia Standard

Topdressing existing lawns and mixing into existing soil when preparing areas for sowing lawn seed or laying instant turf

Not suitable for

Scotts Lawn Builder™ Topdress is not recommended for use on garden beds

Do not use on lawns less than 8 weeks old - from germination of seed or installation of instant turf

How it works

  • Topdress Mix adds organic matter to impoverished soils to improve soil texture, moisture holding and overall soil health
  • When applied as a topdressing, it can be used to remove hollows that may have developed
  • Provides a healthy soil environment for sowing lawn patching and repair products
  • Its nutrients are released at about the same rate that grass roots can take up the fertiliser so there is no wastage, run-off to waterways or damaging surge growth

How to use

  1. Topdress Mix may be spread thinly over an existing lawn alone or in combination with over-seeding to boost lawn density
  2. Spread evenly over the grass and rake to level the area. If over-seeding, use quality seed and follow package directions.
  3. For lawns that have a build up of dead grass under the green top growth ("thatch"), raking with a steel tine garden rake followed by aeration with a sturdy fork is recommended before topdressing
  4. To prepare an area for a new seeded or turfed lawn, spray the area with a non-selective herbicide such as Roundup according to label directions at least 10 days before planting, to eradicate all existing weeds and grasses
  5. Dig out dead weeds and grass then loosen the soil. Spread a 2.5cm layer of Topdress Mix and mix into top 2.5cm of existing soil
  6. Spread seed or lay turf and water frequently. After 8-10 weeks, feed with Scotts Lawn Builder™ All Purpose Slow Release Lawn Food

When to use

  • Topdressing an existing lawn is best done in Autumn, after the heat of Summer has passed and before Winter rainfall
  • It can be done at other times of the year but avoid topdressing in mid Summer
  • Sowing new lawns and patching existing grass are best done in mid Spring, allowing time for the seeds to germinate and grass to establish before Summer
  • New turf is best laid in Spring or Autumn - avoid Summer's heat and Winter's cold
