Grass maintenance involves regular practices to keep lawns healthy and attractive. Key activities include mowing, which helps control grass height and promotes even growth, and watering, ensuring the grass receives adequate moisture, especially during dry periods. Fertilization is another important aspect, providing essential nutrients to support growth and color. Additionally, aeration can improve soil health by allowing air, water, and nutrients to penetrate deeper. Regularly removing weeds and debris also contributes to a thriving lawn, making it more resilient against pests and diseases.
