Why You Shouldn’t Lay Sod Over Existing Grass

When it comes to laying new sod, it is essential to avoid the common mistake of placing it directly over an existing lawn. Laying sod on top of old grass can have detrimental effects on the health and establishment of the new turf. Here’s why:

• Root Penetration: The roots of the new sod face difficulty in reaching the soil bed when laid over existing grass. This is because they need to penetrate through the old lawn’s root system first. Such limited access to the soil can strain the new sod, impeding its ability to develop strong, healthy roots.
• Inadequate Nutrient Availability: As time passes, the underlying layer of sod does not decompose but instead transforms into a slimy, nutrient-deprived mess. This slimy layer prevents the new sod from receiving the necessary nutrients for its growth and survival.
• Incomplete Establishment: To ensure the successful establishment of new grass, it becomes necessary to remove two layers of sod. This process is required to create a suitable environment for the new sod’s root system. Laying sod on top of old grass does not effectively address this critical step, hindering the establishment of your new lawn.

Avoiding the temptation to lay sod over existing grass is vital for a lush and thriving lawn. By following best practices for sodding and properly preparing the soil, you can create an optimal environment for your new sod to grow, develop strong roots, and provide you with a beautiful outdoor space.
