To build a garden, you first need an area of nutrient-rich soil that can be easily dug and modified. Most plants prefer a soft, black soil type.

Garden soil mostly consists of dead plant parts. For example, it can contain small, partially decomposed parts of dead leaves. In addition, the soil should contain small grains of sand. Many garden stores also sell peat, which is a type of soil that is produced in bogs.

Earthworms live in garden soil. They are good friends of the gardener, as they help to soften the soil by digging their tunnels.

The garden should be fertilized every year. By doing so, you make sure that the garden soil contains enough nutrients. Nutrients are substances that plants need in order to grow and reproduce. 

There are many types of garden fertilizers. They are sold in garden stores.
