What is Topsoil?

Did you know soil isn't dirt? People use the words interchangeably, but soil is a rich mix that can sustain plant life, while dirt is what you sweep off the floor. Just as important: knowing which kind of soil your garden needs.

Search "sifted topsoil near me" and it's easy to get confused. So let's break down topsoil, garden soil, potting soil and compost, and when to choose each.

What Is Topsoil?

Topsoil is the top layer of soil. During construction, about 12 inches are often scraped off the top of the land, and that's usable topsoil. Its makeup varies by location, but it generally contains silt, clay, sand and organic matter. Sifted (screened) topsoil has been run through a screen to remove clumps and debris.

Why topsoil is so popular

It's affordable and versatile. Use it as a base and mix in amendments like compost to make it even better.

What Is Garden Soil?

Garden soil is topsoil that's been mixed with amendments, fertilizers and organic material for a specific purpose. It comes in different formulas for different plants.

What Is Potting Soil?

Potting soil is fluffy, lightweight and drains fast. It blends organic materials like peat moss with inorganic ones like perlite, plus fertilizers and other additives.

Clean potting soil for cultivation.

Potting soil is light and airy, perfect for containers.

What Is Compost?

Compost isn't soil at all. It's the nutrient-rich organic material left when plant matter breaks down. Since it has no mineral soil, it can't stand alone, but mixed into soil it adds nutrients and moisture and improves drainage and airflow. We sell compost by the yard.

Which One Should You Use?

Topsoil

• Raised beds (enriched with compost)
• General landscaping and grading
• New lawns
• Most cost-effective option

Potting & garden soil

• Containers and hanging baskets
• Specialty plants like succulents
• Vegetable and flower beds
• Formulated for specific needs

💡  Pro tip: Filling a hole or changing your yard's grade? Use cheaper fill dirt for the bulk of it, then top it with a few inches of topsoil or garden soil if you plan to plant.

Bags or Bulk?

Bulk is the easiest way to get a lot of soil, while bags make it easier to move around the yard. Mr. Good Stuff Growing Soil comes in 1.5 cu ft bags, and we deliver topsoil, garden soil and compost in bulk anywhere in Greater Sacramento.
