The Ultimate Guide to Top Dressing Your Lawn
Want a lush, level lawn? Topdressing helps fix uneven spots, enriches your soil, and supports grass growth
What is Topdress?
Top dressing is the adding of a specially blended mix of materials to the surface of a lawn. It will help to produce a thicker, lusher sword across the whole lawn, as well as provides an opportunity to repair lawn patches and damaged areas.
Top dressing helps even out your lawn surface, making other maintenance tasks easier. By leveling out hollows with top dressing, the lawn mower can cut blades of grass to a regular length, so it looks consistent and tidy.
What Are the Benefits of Top Dressing Your Lawn?
If your lawn is really uneven, top dressing can also help to prevent skimming of the surface, where some areas of grass are cut as far down as the soil, creating bare patches. Filling in the gaps, over the course of several treatments if they are deep, gives the treated areas a chance to put on new grass growth before being top dressed again.
Applying top dressing, like Scotts Lawn Builder™ Topdress Mix and Underlay Organic Lawn Soil, to a lawn also means providing fresh nutrients to the roots of the grass. Doing so increases organic activity around the roots of the grass, naturally reducing compaction and increasing air flow. This leads to a healthier lawn which can better withstand typical garden stresses, such as heavy use and extreme weather.

Depending on the type of grass you are growing, you would generally top dress warm season grasses during Spring and Summer. These include Kikuyu, Buffalo and Couch grass. And top dress cool season grasses like Fescues, Ryegrass, Bluegrass and Bentgrass during Autumn months.
What You’ll Need for Top Dressing Your Lawn
Make sure you have the following key tools and equipment:
- Rake
- Lawn aerator
- Lawn mower
- Sprinkler
- Pair of gloves
- Scotts Lawn Builder™ Topdress Mix and Underlay Organic Lawn Soil
- Verticutter (optional)
- Turf groomer (optional)
- Grass seed (optional)
How To Prepare Your Lawn for Top Dressing
Step 1
Start the top dressing process in early Spring, by first aerating and then cutting the lawn. Gently rake the lawn to remove any leaves and other debris, and loosen any heavily thatched or bare patches, so that the top dressing can penetrate the soil.
Step 2
If you have access to a Verticutter, often found in professional settings, this can also be used to cut stolons and break up thatch. Similarly, a turf groomer can be used prior to top dressing to clip horizontally growing blades of grass which a mower would not normally reach. Both of these actions aim to open up the area just above the soil surface, and improve the action of the top dressing.
How To Top Dress Your Lawn
Step 1
Start in one corner of the lawn and work on a small section at a time, walking backwards to avoid stepping on the freshly topdressed areas. Wear protective gloves and apply the top dressing gradually — it’s easier to add more than to remove excess. Use both sides of a garden rake to gently spread and smooth the mix, working it into any dips or hollows as you go.
Step 2
Aim for no more than 1cm or 1/2 an inch of top dressing in the deepest hollows — the grass tips should still be visible so they can keep growing through. If you have any leftover mix, seal the bag and store it for future touch-ups.
Step 3
Once the whole lawn has been top dressed, water with a soft sprinkler to encourage new growth. After a few days, gently rake over the surface again to identify and smooth any errant bumps and hollows.
Perfecting Your Top Dressing
It may take a few shallow applications of top dressing over the course of several months to achieve a perfect surface. Using a proprietary top dressing, like Scotts Lawn Builder™ Topdress Mix and Underlay Organic Lawn Soil, each time will ensure that the lawn receives a steady supply of essential nutrients.
Top dressed lawns can be reseeded afterwards if growth was sparse before. This works well for Kikuyu grass, although Buffalo grass will grow more reliably by allowing existing turf to spread.
That’s the hard work done! Carry on mowing, weeding and feeding throughout the year to keep your rejuvenated lawn looking great.
