To all of our customers and followers here is some helpful advice for Fescue Aeration & Overseeding Care Instructions. If you found this helpful feel free to share it with others!
Proper care during the next several weeks is critical to getting good seed germination and establishing a thick, healthy fescue lawn, but remember these are general rules not a “one size fits all” plan as each lawn can be different.
1. WATERING — MOST IMPORTANT
New seed needs consistent moisture while it is germinating. The goal is to keep the seedbed cool and damp, but never saturated, muddy, or standing in water.
First 2 Weeks
* Water approximately 30 minutes, 2 times per day.
* Ideally, water once in the morning and once later in the day.
* If your irrigation system puts out a large amount of water, you may need to shorten the watering time.
* The soil should remain damp without becoming muddy or developing standing water.
Weeks 3–4
* Reduce to approximately 30 minutes once per day, preferably in the morning.
* Continue monitoring the lawn. Weather and irrigation output may require adjustments.
Weeks 5–6
* Water approximately 30 minutes every other day.
* As the grass becomes established, begin transitioning toward deeper, less-frequent watering.
After Week 6
* If we are not receiving adequate natural rainfall, water approximately 30 minutes every 2–3 days, adjusting as necessary for weather and your irrigation system.
* Once the lawn is established, the general target is approximately 1 inch of total water per week, including rainfall. During hot or dry periods, supplemental irrigation may be necessary.
Important: These watering times are general guidelines. Your irrigation system, soil type, temperature, rainfall, and slope can all affect how much water your lawn actually receives. Slow, consistent soaking is better than flooding the lawn all at once.
Never allow the lawn to remain saturated or muddy.

2. LIMIT TRAFFIC
Keep foot and vehicle traffic to a minimum while the new grass is germinating and becoming established.
* Avoid unnecessary walking on newly seeded areas.
* Keep pets and other activity off the lawn as much as practical.
* Avoid parking or driving on newly seeded areas.
* Heavy traffic can disturb seed, compact the soil, and damage young seedlings.

3. MOWING
Do not mow immediately after overseeding.
Wait until the new grass has reached a relatively uniform height of approximately 4 inches before making the first cut.
When mowing:
* Never remove more than 1/3 of the grass blade at one time.
* Keep the lawn around 4 inches during the growing season.
* During cooler months, the lawn can generally be maintained as low as approximately 3.5 inches.
* During warm weather, 4–4.5 inches is preferred. Taller grass generally develops a deeper root system and can better tolerate heat and drought.
* Keep mower blades sharp to avoid tearing the young grass.
If the lawn is growing unevenly, allow the shorter areas time to catch up rather than cutting the entire lawn too short.

4. LEAVES & DEBRIS
Keep leaves and other debris from sitting on the lawn for extended periods.
This is especially important while the new fescue is becoming established.
* Remove heavy leaf accumulation regularly.
* Avoid allowing leaves to form a thick, wet layer over the new grass.
* Existing turf also benefits from having leaves removed rather than allowing them to remain for prolonged periods.
When removing leaves, use care so you don’t disturb newly established seedlings.

5. W**D CONTROL
Some weeds may appear during the establishment period. Do not apply pre-emergent immediately after overseeding, because pre-emergent products can also prevent desirable grass seed from germinating.
Once the new fescue has become established, typical pre-emergent application windows are:
* Late February–early March
* Late April–early May
Exact timing can vary depending on weather and soil temperatures.
If you are unsure whether a product is safe to use on your newly established lawn, contact us before applying it.

6. LONG-TERM WATERING
Once the new fescue is established, move away from frequent light watering and toward deeper, less-frequent watering.
A healthy established lawn generally needs approximately 1 inch of water per week on average, including rainfall.
During periods of hot, dry weather, you may need to supplement rainfall.
The goal is to encourage the roots to grow deeper rather than keeping the surface constantly wet.

7. WINTERIZING IRRIGATION
Before the first hard freeze or extended period of below-freezing temperatures:
* Drain irrigation lines where applicable.
* Disconnect and drain hoses.
* Remove watering timers.
* Bring timers and other removable irrigation equipment inside a house, garage, or other protected area.
* Do not leave water-filled equipment exposed to freezing temperatures.

THE BIG THREE
If you remember nothing else, remember these three things:
1. Keep new seed consistently damp — not soaked.
2. Don’t mow until the new grass reaches approximately 4 inches.
3. Keep traffic, leaves, and other disturbances off the new grass while it establishes.
