Before we break into dethatching basics, let’s break down what thatch is, how to deal with it, and introduce a new, easier way to reduce it—Thatchzyme.
What Is Thatch?
Thatch is a layer of dead and living organic matter—like roots, stems, and grass clippings—that builds up between the green grass and the soil. A thin layer (under 1 cm) is normal and even beneficial, helping retain moisture and protect the soil. But when it gets too thick, it blocks water, nutrients, and air from reaching the roots, leading to weak, disease-prone lawns.
How to Dethatch
Traditional dethatching involves physically removing the layer using:
- A dethatching rake – great for small areas but hard work.
- A powered dethatcher (scarifier) – ideal for larger lawns, but can be aggressive and leave your lawn looking rough for a few weeks.
- A hollow corer, pulling plugs of thatch and soil out from your lawn.
After dethatching, it’s important to fertilise and water well to help your lawn recover.
How to Dilute Thatch
If your thatch layer isn’t too thick, you can dilute it by:
- Aerating – punching holes in the soil to improve microbial activity.
- Topdressing – applying a thin layer of sand to encourage decomposition.
When to Dethatch
The best time to dethatch is during your lawn’s active growing season:
- Warm-season grasses (like couch or kikuyu) – late spring to early summer.
- Cool-season grasses (like fescue or rye) – early autumn or spring.
Avoid dethatching during extreme heat or drought—it stresses the lawn and slows recovery.
A New Way to Reduce Thatch: Thatchzyme
Mechanical dethatching isn’t for everyone. That’s why we have Thatchzyme—an enzyme solution that helps break down thatch naturally. Used in combination with mechanical methods you can get on top of your thatch problems with ease.
How Thatchzyme Works
Thatchzyme contains a blend of enzymes that digest the organic matter in the thatch layer. Simply apply it with a backpack sprayer, and let nature take over.
- No damage to your lawn
- No downtime or recovery period
- Safe for pets and kids
- Works over time with regular use
