WHEN IS THE BEST TIME TO SCARIFY TO REMOVE THATCH FOR THE BEST LAWN

Scarifying a lawn, also known as lawn dethatching, is the process of removing thatch—a layer of dead grass, roots, and organic matter that can accumulate on the soil surface. Here are several reasons why scarifying is beneficial for your lawn:

1. Improves Airflow : Removing thatch allows better air circulation to the grass roots, promoting healthier growth.

2. Enhances Water Penetration : Scarifying helps water reach the root zone more effectively, reducing runoff and improving moisture retention.

3. Nutrient Absorption : By removing the thatch layer, scarifying enables fertilizers and nutrients to penetrate the soil more easily.

4. Promotes Healthy Growth : It stimulates new grass growth by encouraging the development of new shoots and roots.

5. Prevents Pests and Diseases : Excessive thatch can attract pests and disease, so scarifying can help minimize these risks.

6. Improves Overall Lawn Health : Regular scarifying contributes to a thicker, healthier lawn that can better withstand drought and foot traffic.

The Petrol Scarifiers will need a trailer or large SUV for transport - we have trailers for hire @ $5 per hour if needed.

Suggested preparation for Scarifier:

• Mow the lawn 2-3 days prior
• Mark out any irrigation heads.
• Scarifier at least twice in different directions

Post Scarifier 

• Collect up the thatch (rake or mow)
• Spread topdressing mix (ours is a blend of Composted Sawdust and Sand)
• Add seed if required
• NZLA Tonics and Fertilisers (See below)
• Water in

• Aim to dethatch just enough to remove excess thatch.
• If you're cutting into the soil profile, you're going too deep.
• A properly dethatched lawn should only take a week to recover.
