New Sod Installation Guide: When and How to Mow Your Fresh Lawn

After laying new sod, you should wait until the grass has established a strong enough root system before mowing it. Typically, you should wait about 2 to 3 weeks before mowing newly sodded grass. Here’s a general timeline for mowing after sod installation:

  1. Initial Watering: Immediately after laying the sod, water it thoroughly to ensure good soil-to-sod contact and to help the roots settle.
  2. Root Establishment: Allow the newly laid sod about 2 to 3 weeks to establish its root system. During this time, the roots will penetrate the soil, and the grass will become more stable.
  3. First Mowing: After the waiting period, inspect the grass to ensure that it has taken root and is firm when gently pulled. When the grass reaches a height of approximately 3 to 4 inches, you can mow it for the first time.

When you do mow for the first time, follow these guidelines:

  • Set your mower blade at a higher setting, typically around 3 inches or slightly higher. Avoid cutting more than one-third of the grass blade’s height in a single mowing.
  • Use a sharp mower blade to prevent tearing or damaging the newly established grass.
  • Mow when the grass is dry to achieve a cleaner cut.

Remember that the timing for mowing after sod installation can vary depending on factors such as the type of sod, local climate conditions, and the rate of root establishment. It’s crucial to observe the grass’s growth and development before mowing and to be gentle during the first few mowings to avoid stressing the newly laid sod.
