When you look at the ground, you might think soil is just dirt. But healthy garden soil is actually made of many different things working together. Soil is like a home for plant roots, and healthy soil helps plants grow strong and productive.

Soil contains tiny pieces of rock that have broken down over time. It also contains water, air, and organic matter. Organic matter is made from things that were once living, such as leaves, plants, and other natural materials that have decomposed.

Healthy soil holds water for plants without becoming too soggy. It also allows air to move around the roots. When soil is too hard and packed together, roots can have trouble growing. When soil is too sandy, water may drain away too quickly.

Many living creatures call soil home. Earthworms, insects, fungi, and tiny organisms all help improve the soil. Some break down organic matter, while others help move nutrients through the soil. Even though many of these helpers are too small to see, they play an important role in a healthy garden.

Gardeners often spend as much time caring for their soil as they do caring for their plants. Healthy soil gives plants a strong foundation and helps gardens thrive throughout the growing season.

Try It!

Gather a small sample of soil from your garden or yard and place it on a piece of paper.

Look closely at what you see. Can you spot tiny rocks, roots, pieces of leaves, or insects? Use a magnifying glass if you have one.

Next, gently squeeze a handful of soil. Does it feel crumbly, sticky, sandy, or smooth? Different soils feel different because they contain different materials.

Draw a picture of your soil sample and label everything you can identify. You might discover that soil is much more interesting than it first appears!
