Issues with Laying Sod Over an Existing Lawn

Jan 7

It's understandable that you'd want to know how to lay sod over an existing lawn. After all, why bother tearing up your old lawn when you can simply lay down a new one? This approach, however, has several serious flaws. Here, Fort Worth Landscapers will go over those issues and provide helpful hints for properly laying sod.


The Roots Do Not Make Contact

While it may not be the answer you want to hear, the answer to "Can I lay sod over existing grass?" is always no if you want good results per Fort Worth Landscapers. One of the most important reasons why you should not lay sod over an existing lawn is that the roots of the sod will not make contact with the soil beneath. This means that the sod will have a more difficult time taking root and may eventually die. To avoid this issue, make sure that the sod's roots are in contact with the soil. This can be accomplished by removing the old lawn before laying down the sod. This will help guarantee that your new sod gets off to a good start.


Sod Likely to Die

Another issue with laying sod over existing grass is that it greatly increases the likelihood of the sod dying. If the sod cannot reach the soil, it will not be able to obtain enough water to survive. Lawn Care Fort Worth pros insists this is especially problematic if your old lawn has a thick layer of thatch. The thatch will obstruct the new sod's ability to absorb nutrients. To avoid this issue, make sure that the sod is in direct contact with the soil below.


Drainage Problems

New sod has different drainage requirements than established lawns. Landscapers in Fort Worth know if you lay sod without first preparing the soil, the new sod will compete for water with the existing turf. This can cause drainage issues and eventually kill the new sod. To avoid this issue, make sure the soil is properly prepared before laying down new sod. This includes clearing away any obstructions to drainage, such as rocks or roots.


Uneven Appearance

The final major issue with laying sod over an existing lawn is that it can create an uneven appearance as suggested by Fort Worth Landscapers. This is because when new sod is laid on top of old grass, there are visible height differences. If your new sod survives, you'll probably end up with a bumpy surface that's difficult to walk on, let alone mow. To avoid unsightly high or low spots, prepare the soil by removing existing grass and then laying the sod as level as possible with the ground. The end result will be a green, even lawn that is both visually appealing and safe for regular use.


Best Time to Lay Sod

The good news is that you have some leeway when it comes to laying sod. Sod can be laid as long as the weather is warm (ideally spring, summer, and in some locations fall). The key to ensuring that your sod takes root and grows into a healthy lawn is to use freshly cut sod (within the past 24 hours). Although you have some leeway in terms of timing, Lawn Care Fort Worth experts recommends you don't want to waste time laying your freshly cut sod. Water your sod within 30 minutes of installing it. Water your sod enough to keep the soil beneath it moist. This will give it a good start by assisting the roots in taking root & helping them grow.


With so many potential pitfalls, it's easy to see why laying sod over existing grass is a bad idea. Instead, it's best to remove your old lawn to give your new sod the best chance of growing green and healthy.
