When you are planting sod, it is important to get the right soil mixture. This balance of ingredients will help your new sod thrive and grow and keep weeds from taking over.
What Is Topsoil anyway? To understand why sod needs Topsoil (or not), we first have to understand what exactly Topsoil is.
Topsoil is usually defined as the layer of soil directly above the subsoil in which most of the nutrients and organic matter reside.
Another question is: does sod need Topsoil?
The good thing is that whether or not your sod has Topsoil underneath it, there’s a way to get what you need.
However, if you are using sod to replace an old lawn or simply add some greenery to your yard, sod is a great option.
But before you plant them, there are a few things you must know about sod and Topsoil.
Read on to find out more.
What Is The Best Soil To Put Under New Sod?
The best soil to put under new sod is loamy soil, moist and filled with organic matter. If you want to use Topsoil, the soil must be well-drained.
Topsoil should not be allowed to get too wet or dry out before planting your sod. Some topsoil will work better than others.
The best Topsoil for laying sod will have a pH of 6.5-7.5, be slightly acidic, and consist of sand and clay.
If you must your soil, ensure it has the proper moisture content (about 60% is ideal).
You can choose to add some sand if you want more depth in your yard.
Remember: the amount of sand is not as important as its physical properties, so don’t worry about getting too much or not enough!
However, if you’re using Topsoil from a bag, ensure it’s not too acidic or alkaline.
If you don’t have access to a professional fertilizer, then use a basic formula of 10-10-10 for the first application (1 pound per 1000 square feet).
You can also add some compost and bone meal for extra nutrients.
Finally, make sure that your yard is free of debris and weeds before laying the sod.
You can use a broom to clean up any leaves or twigs and then spray the area with water, so it’s moist but not too wet.

What Should I Put Down Before Laying Sod?
Before you lay sod, you’ll need to construct a base for it. You can use any material that is level and sturdy and will hold the weight of your sod.
If you are using good quality garden soil (not heavy clay), it would be effective if you lay sod on top of it.
You must know that any debris on top of your soil will prevent the roots from growing properly and possibly damage them if they grow too deep into the soil.
If you want to ensure that your new lawn looks as good as possible with no weeds or other issues later down the road, then make sure that there are no rocks in your yard when laying down new sod!
They can obstruct water from draining away from where you want it to go and cause erosion.
Rocks can also cause problems if they come into contact with either side of an established turfgrass plant.
This includes paths between plants (which can lead straight back into one another) and around trees where leaves fall onto the bare ground during their lifespan.
You should take this seriously especially if they are in areas where they could cause damage like summer months when temperatures rise above 25 degrees Celsius (77 Fahrenheit).
The best idea is to use a full-depth planting.
This method involves planting your sod deep enough to accommodate the roots, but not so deep that it becomes root bound.
If you do not have Topsoil, then lay down some mulch as an alternative.
If you don’t have a lawn mower or rotary tiller, you may want to consider renting one from your local hardware store.

If you have an existing lawn and want to upgrade it with some new grass growth, consider adding some fertilizer as part of this process.
Can You Put Sod On Top Of Topsoil?
Topsoil is a beneficial addition to your lawn, but it’s also important to know if you need to put sod on top of Topsoil.
You should plant sod on top of good quality topsoil if you have a lot of clay, rocks, or stones on the Topsoil.
It will help improve drainage and keep your lawn healthy and growing.
The best time to install Topsoil is after the first year when new grass grows out of its roots.
You can also add Topsoil around the perimeter of your lawn if you want to grow new grass into an established one.
If you have rich Topsoil, putting sod on top of Topsoil is not necessary.
The rich matter will help improve drainage and allow water to move through the ground more easily.
How Deep Should Topsoil Be For Sod?
The depth of the Topsoil you use for sod depends on the type of sod you use and how deep you want to go.
If you’re using a lawn-like product, such as Kentucky Bluegrass or Zoysia (a hybrid grass), it’s easy: just dig about 6 inches for general use.
It will give your new lawn time to adjust before it gets too high and matted down by weeds.
Moreso, you might have a goal to plant a dense carpet over the entire area with something like St Augustine’s blades or Bermuda grasses.
These are both popular choices among homeowners.
To achieve this, consider digging at least 8 inches into the ground so that each blade has room for growth without being crowded out by other blades nearby (and causing them all together).
Furthermore, planting a lawn that you will use for sports or other high-traffic areas needs to stand up to wear and tear.
You must consider digging at least 12 inches deep to achieve this.
This will enable your new sod time to get settled before it has to endure all the stress of being trampled on by hundreds of feet daily.
5 Steps To Test And Add Topsoil
People often ask whether or not it’s okay to walk on new sod.
The answer is yes, but there are a few things you should know first.
When you walk on newly laid sod, your weight compacts the soil and breaks up air pockets between each piece of grass.
This will reduce water retention in your yard and make it more difficult for roots to grow into the ground.
Here are five practical steps to test and add Topsoil:
1. Test the soil and ensure it is a good one before adding Topsoil.
2. If you have to add Topsoil, you must add it in layers gradually until it is about 1 inch deep.
3. Mix each layer thoroughly with existing soil as you go along!
4. Spread 2–4 inches of new Topsoil; this will create a good environment for any plant to thrive.
5. You should water the newly planted area after you add your new sod and let it stay for some days before walking on it again (this will help prevent puddling)
If you’re planting sod directly on the ground, such as in a garden or natural backyard, then yes, you will need Topsoil.
Topsoil is also known as subsoil or dirt and is a mixture of decomposed organic material like compost, decaying leaves, and other debris.
It helps with water retention, aids in drainage, and provides nutrients that help plants grow quickly.
Your sod depends on where you live.
If your area tends to have sandy soil that drains very quickly, it may not have enough organic matter underneath it to support new sod without some help from Topsoil.
It avoids any problems with drainage and irrigation.
However, if you want to go even further than this and make sure your garden looks even more beautiful, consider adding some mulch around your plants.
Both practices will help keep them looking great all year round!
