September is the Time to Seed Tall Fescue

by Carl J Boxberger, EMGV

September 1 to 15 is the correct time of year to seed tall fescue in the Piedmont Region of North Carolina. Here are seven important steps to follow:

1) Soil Test:  Have your soil tested to determine lime and fertilizer requirements for your lawn area. Soil test kits are available at the Cooperative Extension Office.

2) Site Preparation:  Break up the soil in the area to  be seeded with a rake for small areas or use a lawn coring machine for larger areas.

3) Fertilization: Apply the recommended fertilizer to your lawn. If you have not completed a soil test  then apply a complete N-P-K (Nitrogen-Phosphorus-Potassium) turf grade fertilizer with a 3-1-2 or 4-1-2 ratio (12-4-8 or 16-4-8) at a rate of one pound of nitrogen per 1,000 square feet.

4) Seeding:  Seed with a quality tall fescue blend for sun/shade depending on how much sun and shade your lawn receives. Seed at a rate of six pounds per 1,000 square feet. Stay away from Kentucky 31 tall fescue as there are much better tall fescue blends available. Things to look for are a high percentage of seed germination and a low percentage of weed seeds in the mixture.

When buying grass seed, also make sure the weight of the bag is equal or close to the actual amount of seed in the bag. Some companies add a coating to the seed which is unnecessary and can be misleading. Look closely at the label on the bag to learn what you are buying.

Do not hesitate to ask the personnel at a nursery or other quality garden center for help in choosing the proper seed for your yard’s conditions. The single most important investment in ensuring high quality turf is the purchase of high quality seed.

5) Mulching: Spread straw (without weed seeds) over the seeded area at a rate of one to two bales per 1,000 square foot area.

6) Irrigation:  Keep the top half-inch of the soil moist after seeding. Water the newly seeded lawn lightly two to three times a day for 15 to 20 days as the seed germinates. As the seedlings grow and root, water less often but for longer periods of time which will encourage stronger root growth.

7) Mowing:  Once the newly seeded grass reaches a height of four-and-one-half inches tall, mow the tall fescue back to the proper mowing height of three inches

Suggested Maintenance Fertilization Schedule for Tall Fescue:
September: One pound of nitrogen per 1,000 square feet
November:  One pound of nitrogen per 1,000 square feet
February:  Half to one pound of nitrogen per 1,000 square feet
