The Best Time to Plant Grass in Northern Indiana

Zone 5

• Northern Indiana is in USDA Plant Hardiness Zone 5, which is typical of the Midwest. The winters are a little colder and the summers a little milder than the southern half of the state.

Best Season

• Spring planting is acceptable, but late summer into early fall planting is better. The grass lays down roots through two growing seasons before the harshness of summer heat can dry it out.

Dates

• August 15 through September 15 is the best time for grass seed planting, according to Indiana's Purdue University Turfgrass Program.

Early Planting

• The earlier the seed is planted during the recommended dates, the better. The weather rapidly turns cooler and the sunlight hours shorter.
