HGT Sod is an improved bluegrass sod developed by Barenbrug International. HGT stands for Healthy Grass Technology, and lives up to that name by demonstrating unmatched toughness and disease resistance. HGT was developed in harsh climatic conditions, specifically to withstand diseases, pests, and traffic. HGT is especially unique because of its ability to thrive into the warmer transition zone where other bluegrass varieties struggle. When using HGT sod, your project will receive the most advanced bluegrass sod from one of the highest quality sod farms in the nation. HGT thrives from the transition zone of the United States north.
