Overseeding is highly beneficial for your lawn, as it involves spreading seeds across it to fill in bare, patchy areas, increasing its overall density. The best season for overseeding your turf in Iowa is the fall. That's because the soil temperatures are ideal for seed germination, and they'll have enough time to establish and grow into new grass before winter sets in. Additionally, a denser lawn in the fall means fewer winter weeds since there's less room for them to pop up! On the other hand, you shouldn't overseed in the spring because many weeds germinate during this time, and you can't use pre-emergent weed control treatments because they'll also prevent your grass seeds from growing. They also won't be well-established enough by summer to withstand the heat.

Overseeding in the fall provides ideal conditions for seed germination and establishment.

The fall season is best for overseeding your lawn in Iowa because the cooler temperatures provide ideal conditions for seed germination and establishment! After all, cool-season seeds are used, and the soil temperatures during this time are perfect for them, meaning they'll have an easier time developing and yield more successful results.

Additionally, overseeding in the fall will give the seeds enough time to grow into new grass before the winter season sets in. That's because the temperatures remain cool, speeding up their establishment in the soil and increasing your turf's density in time for dormancy.

It's best to pair overseeding with fall aeration to set up the seeds for success and get the most out of this service!

Overseeding Your Lawn in the Fall Means Fewer Winter Weeds

Another reason overseeding your lawn in Iowa in the fall is the best time is because it means fewer winter weeds. Since overseeding fills in bare and patchy areas, it increases its overall density, leaving less room for pesky weeds to pop up and cause problems. As a result, your turf will crowd them out, helping it transition into the winter season free of these nutrient thieves.

Why shouldn't you overseed your lawn in Iowa in the spring?

If you try overseeding your lawn in Iowa in the spring, it'll prove ineffective and a waste of money. For one, many weeds are germinating during this time, and you can't utilize pre-emergent weed control treatments because they'll also prevent your grass seeds from growing! Without these applications, your lawn can become overrun with weeds that steal vital nutrients and resources from them, hindering their development. Another reason you shouldn't overseed in the spring is that the seeds won’t have enough time to become well-established before the hot summer months arrive, stunting their progress and likely causing them to die. Then, you'll still be left with a patchy lawn.
