tilize the Sod – Once the sod is installed, you need to fertilize it. That provides the sod the nutrients it needs to grow and spread its roots. For the best results, you need to apply the fertilizer approximately 2 weeks after the sod is installed. Make sure you use natural fertilizer rather than a chemical one. Such fertilizers can cause harm and compromise the lawn’s health. You should also fertilize the lawn once a month. That will ensure your sod receives as much nutrition as it needs to thrive and grow.
