For new gardeners, all soil probably seems the same. However, the potted cactus you keep in your living room won’t thrive in the same soil the marigolds in your garden do, so you can’t use all soil interchangeably.
Potting soil and garden soil are the two most common soil types, so understanding the difference between them is vital if you want your plants and flowers to grow.
If you mainly grow your plants in containers, potting soil is the best option. If you’re looking for soil specifically for your garden beds, though, garden soil is the better option. Keep reading to learn all you need to know about each type, so you always make the right choice for your gardening projects.

Despite its name, potting soil doesn’t contain soil. Instead, the mixture, sometimes called potting mix, features a blend of peat moss, perlite, bark, compost and other rocks and minerals.
Because it’s soil-free, you don’t have to worry about potting soil containing any fungus or other microorganisms that might be harmful to your plants. It is a safe option for plants grown in pots and features a loose texture that allows it to drain more effectively, so you don’t have to worry about the roots getting too wet.
You can find some potting soils that contain added fertilizers or crystals to help the plants retain water. Special potting soil blends are also sold for specific plants like roses, orchids and succulents. There are even custom blends for starting seeds.
Potting soils are available in bags in various sizes. It usually costs between $0.30 to $2 per pound.

Garden soil contains topsoil that’s fortified with compost, sand, clay, loam and other organic materials to provide plenty of nutrients for plants. It’s heavier than potting soil and retains water more effectively.
Because it’s nutrient-rich and holds water well, garden soil is ideal for in-ground plants and garden beds. From time to time, though, it usually requires amendments to give it the proper consistency and restore lost nutrients.
Like potting soil, garden soil is available in bags in a range of sizes. You’ll typically pay between $0.20 to $1 per pound.

This garden soil features an organic formula with earthworm casings and peat moss to provide plenty of nutrients for in-ground plants. It doesn’t contain any insects either and works particularly well for plants grown in shady areas. The soil is somewhat heavy, though, so it isn’t the best option for all plants.

Miracle-Gro All Purpose Garden Soil
We love this garden soil for annuals, perennials, vegetables, fruits and other in-ground garden plants. It’s fortified with continuous-release plant food to help promote healthy growth for up to three months. Some buyers complain about quality control issues, though, with some bags containing many twigs.
It all depends on where and how you’re planting. If you’re growing plants in pots and other containers, potting soil is the way to go. For in-ground plants, you’re better off with garden soil.
