Aeration is one of the most effective ways to break up compacted soil, improve drainage, and encourage deep root growth. Whether you're using a manual core aerator or a powered machine, this guide walks you through each method so you can choose the right one for your lawn and get the best results.
What You’ll Need
For all methods:
- Coring aerator (manual or powered)
- Rake or dethatcher (optional)
- Water source (for pre- and post-watering)
- Powered only: PPE (as per operator guidelines)
Optional products for post-aeration care:
- LAWNZ Amplify – to support root development
- LAWNZ Soil Boost – to increase microbial activity and boost recovery
Step-by-Step Instructions
1. Read the Label & Instructions
If you’re using a powered aerator, always read the operator manual or hire shop instructions before getting started. Familiarise yourself with the safety requirements and machine controls.
2. Prepare the Lawn
- Moisten the soil: Water the lawn a day or two before aerating if the soil is dry. Aim for moist (not soggy) ground to allow the tines to penetrate cleanly.
- Clear debris: Remove sticks, stones, or anything else that could obstruct the aerator or cause damage.
- Mark obstacles: Flag any underground utilities, sprinkler heads, or cables to avoid accidental damage.
3. Aerate the Lawn
Manual Aeration
- Press the tines into the lawn to remove small plugs of soil.
- Use overlapping rows or a crisscross pattern to ensure consistent coverage.
- Apply firm, even pressure to create uniform holes.
- Take regular breaks — it’s hard work and pacing yourself ensures better coverage.
Powered Aeration
- Ensure your machine is in good working order, fuelled (petrol) or charged (battery), and properly set up according to the instructions.
- Start in one corner of the lawn and move in a methodical pattern (e.g. up and down).
- Engage the tines and allow the machine to pull cores from the soil.
- Keep a steady walking pace for consistent tine depth and spacing.
- If you’re not used to physical work, take short breaks as needed — it’s still demanding, even with a motor.
4. After Aeration
- Leave or remove plugs: You can leave the soil plugs on the surface to break down naturally or rake/mow them up once dry.
- Water thoroughly: Give the lawn a deep soak (10–25mm) to help roots recover and nutrients absorb more effectively.
- Fertilise: Apply a product like LAWNZ Amplify to promote healthy root development.
- Add biology: Use LAWNZ Soil Boost to enhance microbial activity and speed up post-aeration recovery.
- Monitor progress: Keep an eye on the lawn for signs of new growth and improved thickness over the coming weeks.
Additional Tips
-
Choose the right method for your lawn:
- Manual aerators are ideal for small to medium lawns or spot treatment.
- Powered aerators are faster and more effective for large areas or heavy compaction.
-
Stay safe:
- Always wear PPE with powered aerators.
- Follow operator safety instructions closely.
-
Make it routine:
- Aerate at least once a year (spring or autumn).
- Lawns with heavy clay or high foot traffic may benefit from twice-yearly aeration.
-
Avoid soggy lawns:
- Never aerate waterlogged or very dry lawns — you won’t get good results and may damage the lawn or tools.
