To start off you will need to clear the existing area before laying down your new soil. Then lightly turn over approximately the top 5 inches of the existing soil, this will loosen the ground and help make sure you get the best from your new topsoil.
A rototiller also does a good job of loosening the soil but you still need to level it. If you are adding topsoil, while it may cost a bit more, it is worth it to have the landscaper loosen the soil first, then apply the topsoil, and then have the landscaper return to mix the 2 soils together.
Early spring is an excellent time to lay topsoil for both your lawn and garden. The soil is typically thawed, and temperatures are beginning to rise. This period is ideal because: The soil is often moist and workable after the winter season, making it easier to spread and level topsoil.
A: Ideally, you should till the soil that's already in your garden (especially if it's compacted) and add a 3-inch layer of blended topsoil, tilling it all together again to create a 6-inch-deep surface layer; this will best mimic real topsoil.
Avoid tilling in wet soil as soil compaction can occur and lead to poor root penetration in the growing season. If it rains, it's best to wait a few days to allow soil to become semi-dry.
It is better to water the topsoil deeply and less frequently rather than more frequent shallow waterings. Most plants with their roots in the topsoil will benefit from this soil management approach and it will help the roots grow stronger and healthier.
It can take 500 to 1,000 years for one inch of topsoil (the upper layer of soil containing the most organic matter and microorganisms) to form through the interaction of bedrock, climate, topography, and living organisms.
Topdressing the lawn should be done right after aeration as it's not nearly so useful to do it without the holes already there. As mentioned, the idea is for the topdressing to mix in with the existing clay soil.
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.
However, if you'd like to use topsoil as gardening soil for cultivating vegetable gardens, you can create a 50-50 soil mix with native soil for improved aeration and drainage. But why shouldn't you use it by itself as a growing medium?
You certainly can use topsoil for potted plants, but that doesn't mean you should. If you do, your plant probably won't get the nutrients it needs, won't grow at the rate you expect and will be likely to die sooner. The best topsoil for vegetable gardens may not be topsoil at all.
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.
Usually, 8 inches of topsoil is needed to fill a new garden bed or raised bed. If you intend to add topsoil to your lawn, you will need approximately 4-6 inches of topsoil to give you the healthy lawn you desire.
Other than just soil, topsoil is also made up of a mix of rocks, water, contaminants and other organic materials like plant roots, sticks and weeds. In it's raw state like this it isn't very useful, because these rocks, sticks etc will hold back the roots of new plants from sprouting and can restrict water flow.
Any time you stir up soil and water it, you'll get weeds – even if added soil was "clean." Weed seeds are typically throughout topsoil, and it's when they're brought close to the surface and watered that they germinate.
After aerating, it's time for top dressing: spread either pulverized top soil or a good quality humus compost across the lawn. You don't need much—about a quarter inch or so is adequate. Then, go ahead and reseed. Be sure to invest some money in the seed and get good quality, weed-free seed.
You should apply a 2-3cm layer of topsoil before laying down grass seed as the new grass shoots won't be able to push through the topsoil.
For best results, aerate the lawn first, then spread seed and fertilizer afterwards. Going in this order - aeration, seeding, then fertilizing - allows the seed and fertilizer to fall into the aeration holes and make full contact with the soil.
Most types of grass can grow through 2 inches of topsoil placed on top of it if the existing established plants are healthy. Grass often grows through topsoil when a thinner layer of topsoil is placed on top of an old lawn.
Degraded soil makes growing food more difficult and expensive. Without healthy soil, farmers won't be able to grow nutrient-dense food to feed our growing population. The calculated loss in the region is part of a critical issue; some experts suspect that Earth will run out of usable topsoil within 60 years.
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 Myth 4: Rich Soil Never Needs Fertilizer
Those nutrients usually need to be replenished every so often for the healthiest growth, no matter which type of soil you have. This is especially true for the soil where you grow annual flowers and vegetables, which suck up a lot of nutrients to fuel their rapid growth.
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. Please note that before applying topsoil over existing grass, you will need to mow the turf first.
