Gardening Basics: Is Garden Soil the Same as Topsoil? While they have their similarities, garden soil is not the same as topsoil. Topsoil, as the name implies, is the very top layer of soil. Topsoil is dense with minerals and organic matter, which gives it a much darker color than other gardening soils.
But why shouldn't you use it by itself as a growing medium? Due to its poor soil structure, topsoil isn't a good medium for plant roots or even flower beds.
For example, topsoil will be a better choice if you are filling a large land area. This is because it is relatively cheaper and will offer better coverage than lawn soil. In a smaller land area, lawn soil may be better because it is specifically designed to provide necessary nutrients to plants.
Do not use topsoil alone in containers. It can become compacted and saturated with water limiting air space that is important for healthy plant growth. Topsoil is occasionally added to potting mixes in large containers for increased moisture-holding and added weight needed to support large plants.
After all, plants rely on topsoil—the uppermost layer of the earth's surface—for water and necessary nutrients. The more organic matter it has, the darker the soil will look (like what you may see sold in bags or bulk as "black dirt"). This type of soil is very easy to dig in and supports healthy plant growth.
Soil Depth is Crucial
Topsoil is typically thought of as the top 6 inches of soil. We recommend adding at least 2 to 3+ inches of topsoil and rototilling it 2 to 3+ inches into the existing dirt to get the recommended 6 inches depth.
Topsoil Can Help Care for Flower and Garden Beds
One of the best ways to replenish the nutrients that your plants crave is through a fresh layer of topsoil. As mentioned before, topsoil features decomposed plant matter (or organic matter) which helps to nourish your plants.
While the basic peat moss, pine bark and perlite type potting mixes will work fine for almost all annual flowers and mixed potted plants, there are some crops for which specialty mixes might be helpful. The most common is potting mix for orchids.
Garden soil is best for outdoor, in-ground applications.
The ideal soil for most plants is loam, which has a balance of sand, silt, and clay.
There are three main types of soil: sand, silt, and clay. The best soil for most plants to ensure optimum growth is a rich, sandy loam. This soil is an even mixture of all three main types of soil. In most cases, you'll need to amend the soil with compost.
The main disadvantages of topsoil are that it can be difficult to predict its quality, it may contain pollutants and weed seeds, and it can be expensive. The quality of topsoil can vary greatly depending on the region and the supplier.
Topsoil, on the other hand, contains natural organic matter from leaves, grasses, weeds and tree bark that can help sustain plant life. However, topsoil is not enriched or amended at all, which limits its use as a growing medium.
If you're looking for a short answer, then yes, you can put topsoil over grass and existing garden lawns. Although it's possible for grass to grow through the topsoil, this can only be successful depending on the thickness of topsoil applied as a top dressing.
Over time, mulch will break down and effectively become topsoil but it shouldn't be used in lieu of topsoil. That said, while you could leave your topsoil uncovered, it is wise to cover it with mulch to avoid erosion from the rain and overheating from our hot sun.
Top soil provides the nutrients and minerals your plants, vegetables and shrubs needs to flourish and grow into healthy, happy plants. There are many different uses for topsoil including using it to build gardens, fix lawns and make drainage better.
The seller is providing soil, not fertilizer. Topsoil may provide tiny amounts of nutrients, but don't avoid soil testing because you think nutrient problems have been resolved.

A basic autoflower soil could be inexpensively made simply by blending 80% supermarket soil with 10% coco and 10% perlite. That can be mixed simply by hand in a bucket. Combine that soil with a (preferably large) airpot or fabric grow sack and you have a solid foundation for your autoflower seed grow.
Garden soil can be used as the base of a homemade potting mix, but it should never be used straight in outdoor pots. Using any soil in a potting mix is not ideal, though. You are much better off using potting mix to make sure that you have the right balance of aeration, drainage, moisture retention and nutrition.
Potting soil can be mixed with garden soil for particular cases such as raised beds, but it's not a good mix for containers.
Good quality topsoil contains a rich mix of nutrients necessary for healthy plants. It appears darker than subsoil because of the organic matter it contains. The right type of topsoil retains water as well as nutrients, promoting healthy plant growth. A rich layer of quality topsoil ensures healthy lawns and gardens.
On an average, it takes about 100 years to produce ONE INCH of topsoil; like any other resource soils must be managed, protected, conserved, and maintained if they are to continue feeding the ever hungry peoples of the world.
