The answer to 'sod installation not growing' is that there are several common causes, including improper soil preparation, inadequate watering, and pest or disease issues. Symptoms may include patchy or uneven growth, yellowing or browning of the grass, and slow or stunted growth.
To troubleshoot and fix sod that is not growing well, first check the soil moisture and ensure the sod is getting enough water, especially during the first few weeks after installation. You should water the sod deeply and consistently, applying about 1-2 inches of water per week. Next, inspect the soil for any compaction or drainage issues that could be preventing proper root establishment. Aerate the soil if needed. Finally, monitor for any signs of pests or disease and treat accordingly. If the issues persist, it's best to consult a professional landscaper who can diagnose and address the underlying problems.
