You’ve just laid down fresh sod, expecting a lush, green lawn. But instead, you're seeing brown patches that make your yard look worse than before.
This is a common issue, especially in hot, dry climates like Utah.
Based on insights from experienced lawn care professionals, here's how to identify and address the problem.
1. Watering Issues: Too Little or Too Much
Brown patches often result from improper watering. New sod requires consistent moisture to establish roots. If the soil dries out, the grass can turn brown and die. Conversely, overwatering can lead to fungal diseases.
Action Steps:
Water your sod daily for the first two weeks, ensuring the soil remains moist but not soggy.
Adjust your sprinkler system to provide even coverage across all areas.
Monitor the soil moisture by checking if it's damp about an inch below the surface.

2. Heat Stress and Soil Compaction
High temperatures can cause heat stress, leading to brown patches. Compacted soil prevents water and nutrients from reaching the roots.
Action Steps:
Water early in the morning to reduce evaporation and allow the grass to absorb moisture.
Aerate your lawn to alleviate soil compaction and improve water penetration.
Apply a wetting agent to help water infiltrate hydrophobic (water-repellent) soils.

3. Fungal Diseases and Over-Fertilization
Over-fertilizing or using the wrong type of fertilizer can burn your grass, while certain fungi thrive in moist, warm conditions, causing brown patches.
Action Steps:
Use a slow-release nitrogen fertilizer to provide steady nutrients without overwhelming the grass.
Apply fungicides if you suspect a fungal infection, following the manufacturer's instructions.
Avoid fertilizing during extreme heat to prevent additional stress on the grass.

4. Environmental Factors: Reflections and Soil Composition
Reflections from windows can create hot spots that scorch the grass. Additionally, areas with poor soil composition, such as sandy or gravelly spots, may not retain moisture well.
Action Steps:
Install window films or shades to reduce reflective heat.
Amend poor soil areas with organic matter to improve water retention.
Consider re-sodding or reseeding areas with persistent issues, ensuring proper soil preparation.
5. Pest Infestations
Grubs and other pests can damage the roots of your sod, leading to brown patches.
Action Steps:
Inspect the affected areas by lifting the sod to check for white, C-shaped grubs.
Apply appropriate insecticides if pests are present, following safety guidelines.
Maintain a healthy lawn through proper watering and fertilization to deter pests.
