According to the text, garden soil is a type of soil that is mixed with organic matter like compost, peat, bark shreddings or fertilizer and is used in outdoor gardening. It is less variable than potting soil, which is used alone for container plants. Potting soil is specifically designed for potted houseplants and is lightweight and sterile. Both garden soil and raised bed soil are important for providing a suitable growing environment for plants, but they have different compositions. Raised bed soil contains a higher percentage of organic material and nutrients compared to garden soil. Therefore, it is important to understand the difference between garden soil and potting soil. Overall, garden soil is composed of ground rock and organic material, while potting soil is created with added substances to be used alone.
