What is Topsoil?
True to its name, topsoil refers to the surface layer of your garden's soil. This may cover a depth of up to 2 to 8 inches. It is considered the most crucial section of your yard soil. Applying topsoil for grass seed (or top dressing) refers to putting a layer of rich organic topsoil mixes on your lawn.
Benefits of Topdressing a Lawn
So, when do you need topsoil for grass seed? This is usually required when the soil starts to be plagued with issues, so pulling all the grass away isn't a practical solution.

What Topdressing Material to Use
When determining the best topsoil for grass, you must select the suitable topdressing material for your lawn. Experts recommend using a topdressing material that has a similar texture and composition to your lawn's underlying soil.
Meanwhile, choosing an unsuitable material may lead to severe problems. It may lead to having a distinct layer that may hinder air and water movement, which affects your turfgrass development. Commonly, the most popular topdressing material options include high-quality compost and a custom-blended mix.
Important Note: The above materials can be bought from your local nurseries or garden centers. If you're looking for topsoil or sand, you may drop by your nearest landscape or construction company.

Frequently Asked Questions (FAQs)
Should I fertilize the lawn before topdressing?
Yes, you can fertilize a lawn before applying a topdressing, but it's optional. If you choose to aerate, the fertilizer should be used after and before topdressing. The growth and health of the lawn will be improved with this additional fertilizer boost.
Does topsoil differ from garden or potting soil?
Yes, given that topsoil weighs more than potting soil. Vermiculite (also known as peat moss) is commonly introduced to solid soils to achieve a light, fluffy texture. This helps plants thrive in pots and can also be added to clay soils to lighten the texture. Many garden soils are added with extra organic matter to provide sufficient nutrients. Since potting soils are considered too light to hold in moisture, they may not hold together in a garden bed setting.
Do I need to water the lawn after topdressing?
Once you've completed topdressing your lawn, it is best practice to water it thoroughly. Keep in mind that plants often get stressed when dealing with new changes. Irrigating your yard helps the grass cope with the transition.
When can I mow the lawn after topdressing?
Experts advise against mowing the lawn immediately after topdressing. Instead, wait for at least a week or up to 10 days before trimming the grass.
