What can you do about earthworm castings on the lawn?

Earthworms are very useful and should never be controlled. They improve soil structure, loosen the soil, and promote better aeration.
However, earthworm castings can be a problem because they make the lawn look messy, make mowing more difficult, and can quickly turn the lawn into a muddy mess when it's wet.

Here's How to Properly Handle Earthworm Castings

1. Manually remove or spread out the piles

• Do not walk on the lawn while it is wet

• Only after the grass and droppings have dried:

  • Spread carefully with a broom or rake
    This prevents the lawn from getting smudged and keeps the grass intact.

2. Mow regularly

• Mowing regularly helps break up the clumps

• Be sure to mow only when the lawn is dry
  Otherwise, it quickly turns into a muddy mess when it's wet.

3. Targeted Reduction of Causes

Earthworms prefer:

• wet ground

• compacted soils

• clay-rich soils

What helps:

• Aeration with Tinyspoons (1–3 times a week)
  → Loosens the top 5 cm of soil
  → The surface becomes more porous and dries faster
  → The number of earthworm castings is decreasing significantly

• Aeration with Hollow Spoons + Followed by Sanding
  → Very effective against compaction and waterlogging
  → However, limit this practice to 1–2 times a year, as it puts more stress on the lawn
