Fall Seeding of Lawn

September is the best time to plant cool-season grasses in Kansas, but homeowners should take note of an important fact before choosing which variety to plant. There are several varieties to choose from and they all have their benefits and detriments.

It is important to read the label, you should look for seed that lists weed seed at less than 0.01%, but 0% is best. Another point is to check the listing for ‘Other Crop’ on the label, as well, and choose a grass seed with a low percentage. ‘Other Crop’ includes any species grown intentionally such as turf and pasture grasses.

Some species of grassy weeds qualify as ‘Other Crop’ and legally do not have to be named if they constitute less than 5% of the contents. ‘Other Crop’ can also include more desirable species that won’t impact the lawn.

Here are some other tips for seeding fall lawns:

Seeding new lawns

• Use recommended seeding rates and distribute well.
• Good seed to soil contact is critical. Topdressing and raking to cover seed are other good methods.
• Light, frequent irrigation is necessary the first few weeks after planting, soil should remain moist, but not waterlogged.
• Minimize traffic on the area until seedlings are ready to be mowed.

Overseeding an existing lawn

• Prior to planting, mow the area low (1 to 1 ½ inches) to reduce competition with seedlings and help improve seed contact with soil.
• Water light, but often, keeping soil moist but not waterlogged.

Fertilize cool-season grasses

• Use a quick-release source of nitrogen.
• Apply 1 to 1 ½ pounds of actual nitrogen per 1,000 square feet.
