Why are earthworms good for plants?
Earthworms are a common sight in gardens, backyards, and parks everywhere moving about through dirt and grass. It’s no wonder why these slimy crawlies are gardener’s best friend. They act as little plow especially around Springtime when plants need better soil to grow. As they move through the soil, earthworms like to feed on organic matter and squeeze itself creating networks of tunnels lined with the undigested waste they leave behind. They break up the soil to allow air and water to get to the plants. This activity is beneficial to the soil ecosystem, as it aerates and adds nutrients to the soil. Better soil means better plants. And better plants mean better food for humans. On the other hand, without air and water, plants would not grow well. That is why sometimes, plants don't survive if the soil is too dry and compacted.

Just as important, their burrowing helps to aerate the soil, which allows for better air and water penetration to feed plant roots and creates room for healthy root growth. Their activity also neutralizes the acidity and alkalinity of soil and stimulates the activity of soil microbes.
