The Good, The Bad & The Ugly – Why Fall Is the Best Time to Deal With It

If your lawn feels bouncy, patchy, or like it’s just not thriving—it might be time to take a closer look beneath the blades. The culprit? Lawn thatch.

A little thatch is normal—but too much can suffocate your turf. This fall, give your grass a fresh start by understanding the good, the bad, and the ugly of thatch buildup—and learn why EarthSmart’s Thatch Digester is the gentle, natural way to handle it.

✅ The Good Side of Thatch

Believe it or not, thatch isn’t all bad. A thin layer (½ inch or less) can actually:

• Insulate the soil from temperature swings
• Reduce water loss
• Provide cushioning from foot traffic

In healthy, well-maintained lawns, natural soil microbes help keep thatch in check by breaking it down gradually.

❌ The Bad (When Thatch Gets Too Thick)

When thatch builds up beyond ½ inch, it begins to cause trouble:

• Blocks water and fertilizer from reaching roots
• Harbours pests and disease
• Encourages shallow root growth
• Creates uneven, spongy surfaces

😬 The Ugly (If You Ignore It)

Heavy thatch (1” or more) can quickly take over:

• Grass becomes thin and weak
• Brown patches appear
• Water pools on the surface
• Weed invasion becomes more likely
• Spring green-up is delayed or patchy

🍁 Why Fall Is the Best Time to Dethatch

While many people think spring is the season for lawn projects, fall dethatching is more effective—especially for cool-season grasses common in Alberta and much of Canada.

Here’s why fall wins:

1. Cooler temperatures reduce stress on the lawn
2. Grass roots stay active, so your lawn can recover quickly
3. Natural fall moisture supports microbial breakdown
4. Perfect timing for overseeding or fall fertilizing
5. No interference with spring green-up
