Gardeners may poke fun at the grass lover's passion because they know that the same amount of effort is needed to grow their reward crops as it is to tend to those boring yet lush greens. In fact, just as great topsoil allows a flowerbed its head start, there are certain characteristics needed for a luscious lawn.
Loam is considered to be a good mix of sand, silt, and clay. These types of soils, when mixed in the right amounts can lead to topsoil with great aeration, drainage, and moisture retention. You need something that will allow the grass to breath well, spread its roots vertically, and proliferate horizontally.
If you plan on mixing your topsoil with your existing backyard soil, a soil test is necessary. This is to ensure that you have the right amounts of nutrients necessary in order for your grass to grow healthy and strong. Grass is a nitrogen hog so make sure you're starting out with something that is rich in the minerals that your lawn will need. The proper nutrition will also guarantee your grass will root itself firmly and exceed any waylaying weeds.
Another consideration, especially with mixed soil, is the amount of large stones and gravel in your topsoil. Avoid these as they are not really good for anything much except for occupying space and bringing up your purchase's weight. These fillers are not only useless to your plants but also a mowing accident waiting to happen.
Now that you've decided on the right kind for your lawn, it's time to talk about how much you need. A couple of inches may be enough for grass to grow, but the deer you can get their roots, the more verdant and long-reflecting your grass can get. Topsoil that is 20 inches deep matched with infrequent yet thorough sprinkling during the first cycle of your grass will ensure that your grass elongates its roots further down for moisture. This will result in a lawn that does not cost you much in water.
Once you've gotten the soil and grass to work harmoniously, remember that topsoil maintenance is plant maintenance. The two are interlinked and one can be telling of the other. Bald spots in your lawn could signify patches of nitrogen-poor or saline-rich spots. The growth of particular weeds is also telling of what nutrients are missing or in abundance in your soil. So, make sure your topsoil is just as healthy as your grass.
