What Should You Do to Your Lawn Before Spring Growth Starts?

To prepare your lawn for spring in Sydney, start by cleaning up dead material, mowing, checking for compaction, improving low spots and applying the right lawn supplies if needed. Many lawns look tired after winter, but a careful spring preparation routine can help them recover as the weather warms up.

Depending on the lawn condition, you may need premium top dressing, washed sand, turf underlay or soil improvement products. The right choice depends on whether you are improving an existing lawn, levelling uneven areas or preparing for new turf.

Turtle Nursery supplies premium top dressing, turf underlay, sand, soils and landscape supplies for Sydney homeowners, landscapers and trades, with pickup and delivery options available.

Why Sydney Lawns Look Tired After Winter

During winter, many lawns grow more slowly. Some areas can become thin, compacted, patchy or uneven. Shade, cold weather, foot traffic and wet conditions can also affect lawn health.

By early spring, common lawn issues include:

• Thin grass
• Dead leaf material
• Uneven levels
• Compacted soil
• Poor drainage
• Weed growth
• Bare patches
• Low spots

Spring preparation helps the lawn recover before heavier warm-season growth begins.

Step 1: Clean Up the Lawn

Start by removing loose leaves, sticks, dead grass and debris.

This helps you see the real condition of the lawn. It also prevents old material from blocking light, air and water from reaching the soil surface.

Use a rake or blower and remove any large build-up before applying lawn supplies.

Step 2: Mow Before Lawn Preparation

Mow the lawn before top dressing or sanding, but do not scalp it harshly.

The aim is to reduce excess leaf height so material can work down into the lawn surface. Grass should still be healthy enough to recover.

Remove clippings after mowing if they are heavy.

Step 3: Check for Compaction

Compacted soil can stop water, air and nutrients moving properly through the lawn area.

Signs of compaction can include:

• Water pooling
• Hard ground
• Thin grass
• Poor growth
• Heavy foot traffic areas
• Soil that is difficult to push into

Aerating compacted lawn areas before top dressing can help the lawn recover more effectively.

Step 4: Decide Whether You Need Top Dressing

Premium top dressing is useful when an existing lawn needs light levelling, surface improvement or support after aeration.

Top dressing can help:

• Smooth minor bumps
• Fill shallow low areas
• Improve soil contact
• Support lawn recovery
• Improve the lawn surface

For many lawns, a light layer of around 5–10 mm is a practical guide. Do not bury the grass.

Step 5: Calculate How Much Top Dressing You Need

Use this simple formula:

Length × width × depth = cubic metres required

For example, a 50 m² lawn top dressed at 10 mm would need:

50 × 0.01 = 0.5 cubic metres

If the depth is 5 mm:

50 × 0.005 = 0.25 cubic metres

Step 6: Use Washed Sand for the Right Jobs

Washed sand can be useful for some lawn levelling and drainage support work, especially when applied thinly and evenly.

However, sand is not always the right choice for tired or nutrient-poor lawns. If the lawn needs growth support, a lawn dressing product may be more suitable.

Step 7: Know When Turf Underlay Is Needed

Turf underlay is used before laying new turf. It is not usually the same thing as top dressing an existing lawn.

Use turf underlay when:

• Preparing a new lawn area
• Replacing old turf
• Building up a growing layer
• Levelling before turf installation
• Improving poor existing soil before new turf

For many new lawn projects, around 75–100 mm of turf underlay is a practical guide.

Step 8: Avoid Smothering the Grass

One of the biggest mistakes is applying too much material at once.

Whether using top dressing or sand, grass tips should still be visible after spreading. If the lawn disappears under the material, it may struggle to recover.

Apply lightly and evenly. Low spots can be corrected gradually rather than burying the whole lawn in one heavy layer.

Step 9: Water and Let the Lawn Recover

After top dressing or sanding, water lightly if conditions are dry.

Avoid heavy traffic while the lawn settles. Wait until the grass has started growing through the material before mowing again.

Depending on weather and lawn growth, this may take one to two weeks.

Common Spring Lawn Mistakes

Avoid:

• Top dressing when the lawn is dormant
• Applying too much material
• Using poor-quality soil
• Sanding a lawn that needs soil improvement
• Ignoring compaction
• Forgetting to mow first
• Burying grass blades
• Treating top dressing as a quick fix for drainage problems

Spring lawn preparation works best when each product is matched to the actual problem.
