Morning watering: Water your lawn in the early morning to minimize evaporation and reduce the risk of disease.

Avoid overwatering: Overwatering can lead to thatch buildup and fungal diseases. Ensure proper drainage to prevent waterlogged soil. In modern lawn care, smart irrigation controllers have become increasingly popular. These controllers use advanced technology to monitor weather conditions, soil moisture levels, and water usage, allowing for precise and efficient irrigation. Smart irrigation systems can help Bent Grass homeowners optimize their watering routines, ensuring the grass receives the right amount of moisture while conserving water resources and minimizing the risk of overwatering.

Fertilization

Develop a comprehensive fertilization schedule based on soil testing. Use balanced fertilizers to provide the necessary nutrients for healthy growth. Consider slow-release fertilizers to ensure a consistent nutrient supply.

Dethatching

Bentgrass lawns can be susceptible to thatch buildup if not properly managed. Perform dethatching as needed to remove the layer of dead grass and organic matter that accumulates on the soil's surface.

Pest and disease management

Integrated pest management (IPM): Adopt IPM practices to minimize the use of pesticides. Monitor your lawn for signs of pests and diseases and address issues promptly.

Aeration: Ensure proper soil aeration to improve soil oxygen levels and water penetration. Aeration helps prevent thatch buildup and promotes healthy root development.

Climate protection

Protect your bentgrass lawn from extreme weather conditions, such as excessive heat, cold, or humidity. Implement measures like providing shade during scorching summers and protecting against frost during cold spells.

Additional tips

Topdress your lawn with a thin layer of sand in the spring to help improve drainage and reduce thatch buildup. Avoid using weed killers on your bentgrass lawn, as they can damage the grass.
