Nothing should be done about the earthworms themselves, as earthworms are very helpful and improve the soil by bringing air into the soil.
However, the piles of earthworms are usually very annoying and can turn the lawn into a large muddy field.
Here are a few tips on how to deal with and combat earthworm piles:
1. manual removal or distribution of the piles:
Walk on the lawn as little as possible when it is wet and spread the piles with a rake or broom as soon as the lawn and the earthworm piles are dry.
2. Mowing the lawn:
Regular mowing of the lawn tends to disperse the heaps and make them less conspicuous. However, the lawn should also be dry here, otherwise it will be a very muddy affair.
3. effective counteraction:
Earthworms prefer moist, compacted, loamy soils.
If you aerate 1-3 times a week with Tinyspoons, you will definitely ensure a loose, air-permeable surface in the top 5 cm, which will significantly reduce the infestation of earthworm piles.
Aerification with hollow spoon and subsequent sanding also helps enormously! However, you should only do this 1-2 times a year because this measure also means a lot of stress for the grass.
