Gardening is a tough job especially if you don’t know what you are doing. Sometimes the things that seem like the problem are actually the only thing that’s keeping the plants growing. For instance, earthworms may look disgusting but they are important for the plants growth. The earthworms dig through the soil, aerating it for optimum plant growth.

In addition, it also secretes the digested material, which becomes part of the soil and enriches it. All of these different ways are just some of the reasons why earthworms are useful for the soil and help the plants to grow.
