The summer may be over. However, if you have a fescue lawn, it’s time to core aerate and overseed it.


If you have a fescue lawn, a cool season grass, you need to rejuvenate it with core aeration every September.

There are two types of grasses that grow on Oklahoma City lawns: cool season and warm season turfgrasses.

Cool season grasses grow best in cooler conditions. Conversely, warm season grasses grow best in hot conditions.

Oklahoma City homeowners have a mix of cool and warm season grasses on their properties. If the shady parts of your lawn have fescue, then it’s time to core aerate and overseed it.

When your organic lawn care company core aerates your lawn, your technician will use an aerator to pull plugs of soil from the ground. Aeration allows carbon dioxide to be released from the soil, and oxygen to enter it.

Here are five benefits of core aeration:

1.    It loosens up soil compaction 

2.    It allows water and sunlight to penetrate the soil 

3.    It removes excess thatch 

4.    It prepares the soil for fertilization and conditioning 

5.    It prepares the soil for overseeding.

It’s best to aerate your OK lawn between mid-September through mid-October while the soil is still warm enough to encourage seed growth.

After your organic lawn service finishes aerating your lawn, your technician will apply fertilizer directly on top of the open soil.

Fall fertilization contains beneficial phosphorous and potassium—two nutrients that will help develop a strong root system as well as help the turf survive drought, heat and other stressors.

Here are other benefits to fall fertilization:

· Turfgrass grows faster 

· Turfgrass develops hardier crowns, stems and roots 

· Turf seed will germinate faster even as temperatures drop in the fall 

· Turf will be hardier based on the types of nutrition applied to your lawn.

If you plan not to overseed your lawn this fall, your fall fertilizer will contain pre-emergent weed control to protect your turf from winter grassy weeds.

However, if you want your Oklahoma City lawn overseeded, your lawn care technician will not add pre-emergent because it’ll kill your turfgrass seedlings as well as weeds.

So, what’s the big deal about a power seeder?

Well, growing and tending a home lawn is similar to a farmer tilling his fields. A power seeder provides the following overseeding benefits:

· It gives an extra dose of aeration: It further relieves soil compaction and allows the soil to breathe.

· It provides better seed to soil contact: In other words, the seeds are put directly and deeply into the soil. The power seeder allows for more seed to survive germination. It also helps new turf to develop deeper root systems right away compared to broadcast seeding where the seed lands on top of the ground until rain or irrigation helps it to absorb into the soil.

· It partially covers the rows with soil: If you’re familiar with gardening, you know that after a seed is planted, you need to cover it with dirt. A power seeder partially covers the seeds to help them germinate. 

· It provides a more uniform result: When your lawn technician power seeds your lawn, you’ll notice even growth when seedlings pop up through the soil.
