Laying new sod is one of the best ways to reset your lawn

For many homeowners, the state of their current lawns isn’t going too well. Whether there’s an abundance of weeds, or the lawn needs fertilizing and watering, the thought of doing extensive work to the lawn to get it looking green again is just too much to bear. Fortunately, laying new sod is one of the best ways to reset your lawn, creating a beautiful green surface relatively quickly. But there also needs to be extensive preparations made before the new sod is laid out – you can’t simply just lay sod over existing grass and call it a day. Here’s why.

Sod Needs a Solid Foundation

By solid, we don’t mean material consistency – the foundation needs to be free of all external elements in order for the sod to grow well. The best sod base is about two or three inches of loose topsoil free of all debris. This includes old grass, weeds, rocks, trash, roots, and more. This helps the sod establish roots and get the nutrients it needs to grow healthily. With old grass in place, the sod wouldn’t be able to touch the soil and thus roots wouldn’t grow – eventually leading to the death of the sod itself.

Sod Needs Nutrients

In the same vein, sod needs to be able to get the nutrients it needs to survive. If your lawn is in bad shape already, it needs to be revamped to be able to give these nutrients to the sod. Soil needs to have the right pH balance and firmness for the specific type of sod you’re looking to lay down. When a sod expert examines your lawn, they can come up with a thorough gameplan to ensure the ground has the properties it needs to support the new sod.

Sod Needs Water

Freshly cut sod needs to be laid out quickly after delivery because it can dry out really fast. And once it’s laid out, it needs to be watered thoroughly to avoid dehydration and so the roots begin to grow and establish itself within the soil. When sod is laid out on top of existing grass, the water that’s meant to go to the sod will seep through to the grass below away from the new roots. Air then becomes trapped between the two layers, and this can lead to further damage – not just to your new sod, but also to the ground below it.

Long story short, if your lawn needs a fresh start, you’ll need to do more than just cosmetics. A complete revamp of your lawn is possible with sod, but adequate preparation ensures that the sod will be in the best possible situation to grow.
