Overseeding Existing Lawns

 

When To Plant

Centi-Seed can be planted almost any time of the year (even winter) however, warm soil temperatures (70 degrees F.) are necessary for satisfactory germination. Winter seedings will not germinate until spring soil temperatures warm. It is important that seeding be done early enough in the year to get the planting established well enough to endure the first winter.

How Much Seed To Plant

To calculate the area to be planted, multiply the length of the lot in feet by the width in feet to arrive at the number of square feet. Deduct a reasonable amount for buildings, paved drives and walks.

Plant not less than one-fourth (1/4) pound per 1,000 square. One pound per 2,000 square feet often produces a good lawn in two to three months of summer growth. Using plenty of seed is the least expensive part of establishing a good lawn. "Saving" on the cost of seed results in spending more on watering and cutting weeds.

Seedbed Preparation: Till and level the lawn area, removing sticks, stones and debris. If this is not practical, many lawns have been successfully established using the following approach:

  • Apply RoundUp to eliminate or reduce the vigor of the existing lawn grass and weeds and/or scalp the lawn by setting your lawn mower to its' lowest cutting height and mowing. Bag clippings and remove any debris on the surface.
  • Rake or scratch (aerify, scarify) the surface of the lawn to bring some soil to the surface.
  • Distribute seed over the area and lightly rake to insure good seed/soil contact. Use a Cyclone type seeder. Divide seed in half and go over the area twice, sowing from east to west and then north to south to insure uniformity.
  • Mulch lightly with wheat straw if on a slope or to insure adequate soil moisture during seed establishment.
  • Begin irrigation and keep moist for the next three weeks or until seedlings are established.

Fertility at planting - Centipede thrives on and acid soil with a pH range of 5.0 to 6.0 (DO NOT APPLY LIME TO YOUR SEED BED UNLESS SOIL TESTS FOR A CENTIPEDE LAWN INDICATES A NEED.) Do apply 15 lbs. per 1,000-sq. ft. of a complete fertilizer such as 5-10-15 Plus Iron, 10-10-10 or 8-8-8.

 After Planting

Water well immediately after planting, and continue to water as often as necessary to keep soil constantly moist below 1/2 inch. After seedlings emerge, water less frequently until watering only as needed - once the stand is established.

Weeds

Control weeds by mowing frequently until centipede is established.

CAUTION: Do not use a weed and feed fertilizer or any other weed control chemical except Roundup before seeding Centipede because such chemicals will inhibit germination or kill the Centipede seedlings as they sprout!
