Bossier endures 93 extreme heat days, the highest in this group and well above the state average of 84. While the 52.1 inches of annual precipitation is nearly ideal, the high GDD of 6,337 means your lawn will require frequent watering to survive the 83.8°F July averages.

A Balanced Soil for Healthy Grass

Fighting Severe Drought in the North
