It's important to fertilize a newly installed grass sod at the right time to promote healthy growth and root establishment. The timing of the first fertilizer application will depend on the type of grass you have installed and the specific recommendations of the sod supplier or your local extension office. However, as a general guideline, you should wait at least 4 to 6 weeks after installation before applying fertilizer.
During the first few weeks after installation, the sod will be using its energy and nutrients to establish roots in the soil, so applying fertilizer too soon can actually stress the sod and slow down root establishment. Waiting a few weeks will allow the roots to establish and the sod to settle in before applying fertilizer.
When it is time to fertilize, it's important to use a high-quality, slow-release fertilizer with a balanced blend of nitrogen, phosphorus, and potassium. This will help to promote healthy growth and root development without overstimulating the sod or leading to excessive growth that can weaken the grass.
Be sure to follow the manufacturer's instructions for application rates and timing, and apply the fertilizer evenly across the entire lawn. Water the lawn thoroughly after applying fertilizer to help the nutrients to penetrate the soil and prevent them from burning the grass.
After the first fertilizer application, you can continue to fertilize your lawn according to a regular schedule based on the specific needs of your grass and local weather conditions. Be sure to monitor the soil moisture levels and adjust your fertilization practices as needed to promote healthy growth and root development.
