Question of the Day: When Should I Overseed My Lawn?


If you haven’t over-seeded your lawn this September, today is better than tomorrow and tomorrow is better than next week. As fall approaches, days get shorter and night time temperatures drop. Crabgrass, foxtail, and annual grassy weeds turn yellow and shrivel leaving room for turf seed to germinate in cooling soils. September over-seeding helps thicken existing turf eliminating bare spots. Next spring, if no bare spots, there will be no weeds.

Mother Nature has it figured out, after 2 millions years of over-seeding the prairies; we follow her recipe. In their natural growth cycle, grass plants form seed heads and re-seed themselves. Regular mowing eliminates the seed head. Mimic Mother Nature by re-seeding in fall. Over-seeding will introduce youthful vigor and genetic diversity in existing turf. The strongest plants survive and carry on the integrity of the stand. Over-seeding with improved varieties of grass seed will create better quality turf for the future.
