Thatch your lawn: Thatching your lawn will help to remove dead grass and other debris that can provide a food source for earthworms. This can help to reduce the earthworm population and lead to a decrease in castings.

Don’t over-water your lawn

Don’t over-water your lawn: Over-watering your lawn can make the soil more conducive to earthworm activity and lead to an increase in castings.

Earthworms need moisture to survive, but too much water can create an environment that is too wet and conducive to earthworm activity. When the soil is too wet, earthworms are more likely to come to the surface and deposit their castings. Over-watering can also lead to soil compaction, which can make it difficult for water and air to reach the roots of your grass. This can lead to a number of problems, including poor growth, yellowing leaves, and increased susceptibility to pests and diseases.

To avoid over-watering your lawn, water deeply and infrequently, rather than shallowly and frequently. Deep watering encourages the roots of your grass to grow deep into the soil, which makes them more drought-tolerant. It also helps to reduce soil compaction. When you water your lawn, water it until the water penetrates to a depth of 6 to 8 inches. You can check the depth of the water penetration by inserting a screwdriver into the soil. If the screwdriver goes in easily to a depth of 6 to 8 inches, the soil is sufficiently moist. If the screwdriver meets resistance, the soil is too dry and needs more water.

Choose earthworm-resistant grass varieties

Choose earthworm-resistant grass varieties: There are some grass varieties that are more resistant to earthworms than others. Choosing one of these varieties can help to reduce the number of castings on your lawn.

Earthworms are attracted to lawns that have a lot of organic matter in the soil. This includes grass clippings, leaves, and other plant debris. When earthworms eat this organic matter, they produce castings. Some grass varieties produce more organic matter than others. These grass varieties are more likely to attract earthworms and have more castings on the lawn.

If you are concerned about earthworm castings, you can choose a grass variety that is more resistant to earthworms. Earthworm-resistant grass varieties have a thick, dense root system that makes it difficult for earthworms to burrow through the soil. This reduces the number of earthworms in the lawn and leads to a decrease in castings.

Some earthworm-resistant grass varieties include:

Perennial ryegrass
Tall fescue
Fine-leaf fescues
Zoysiagrass
Bermudagrass

When choosing a grass variety for your lawn, be sure to consider your climate and soil conditions. Not all grass varieties are well-suited to all climates and soil types. You can consult with a local lawn care professional to help you choose the best grass variety for your lawn.

Use a mulching mower

Use a mulching mower: Using a mulching mower will help to chop up earthworm castings and distribute them throughout the lawn, making them less noticeable.

A mulching mower is a type of lawn mower that chops up grass clippings and other debris and returns them to the lawn as mulch. Mulching mowers are becoming increasingly popular because they offer a number of benefits, including:

Reduced need for fertilizer: Mulch contains nutrients that are beneficial to your lawn. When you mulch your lawn, you are essentially returning these nutrients to the soil, which can reduce your need for fertilizer.
Improved soil structure: Mulch helps to improve soil structure by adding organic matter to the soil. Organic matter helps to improve soil drainage and aeration, which can benefit your lawn in a number of ways.
Reduced weed growth: Mulch can help to reduce weed growth by blocking sunlight from reaching the soil. This makes it more difficult for weeds to germinate and grow.
Less noticeable earthworm castings: Mulching your lawn will help to chop up earthworm castings and distribute them throughout the lawn. This will make the castings less noticeable and less likely to cause problems.

If you are concerned about earthworm castings, using a mulching mower is a great way to reduce their visibility and improve the overall health of your lawn.
