PART3 - EXECUTION

3.00 SOIL PREPARATION

  1. Prior to planting sod, remove all rocks and debris, eradicate and physically remove all vegetation and weeds, dead or alive, from the site.
  2. Rototill or spade the area to a depth of 4 to 6 inches. Eliminate drainage problems by having soil slope away from foundations, etc.
  3. Incorporate organic matter (humus, redwood, sand, etc.), gypsum, lime and fertilizer as recommended by an approved soils report to a depth of 3 to 4 inches. In the Desert Southwest, incorporate soil amendments into the top 2 to 4 inches of the soil profile.
  4. Rake and smooth the soil, removing rocks, roots, and large clods. Roll the area lightly with a lawn roller 1/3 full of water, leaving the grade 1 inch below finish grade.
  5. Water the prepared area to a depth of 6 inches to settle soil and provide a moist base for turf.

3.01 SODDING

  1. Prior to planting, the irrigation system shall be tested and fully functional.
  2. Sod shall be harvested within 24 hours prior to delivery and planted within three days after harvest.
  3. Install sod immediately upon delivery. In hot weather, protect unlaid sod by placing stacks in shade, covering with moist burlap sacking and sprinkling.
  4. Begin installing sod along the longest straight line, such as a driveway or sidewalk. Butt and push edges and ends against each other tightly, without stretching. Avoid gaps or overlaps. Stagger the joints in each row in a brick-like fashion, using a large sharp knife to trim corners, etc. Avoid leaving small strips at outer edges as they will not retain moisture. On slopes, lay the turf pieces horizontally across the slope. On 2:1 slopes or greater, stake sod to hold in place with 1/2" x 1" x 12" pegs at two-foot spacings. To avoid causing indentations or air pockets, avoid walking or kneeling on the turf while it is being installed or just after watering. Do not lay whole lawn before watering. When a conveniently large area has been sodded, water lightly to prevent drying.
  5. After installing the turf, roll the entire area to improve turf-to-soil contact and remove air pockets.
  6. Begin watering within 30 minutes of installation.

3.02 STOLONIZING

Stolons shall be harvested within 24 hours prior to delivery and planted within three days after harvest.

Install stolons immediately upon delivery. In hot weather, protect unplanted stolons by placing them in shade, covering with moist burlap sacking and sprinkling.

A satisfactory method of spreading stolons shall be employed using a mechanical or power-drawn stolon planter or other approved equipment.

The rate of application of stolons shall be as specified on the plans. Thoroughly water the completed installation immediately after stolon application.

Maintain water saturation of the soil for the duration of the germination period to ensure proper establishment.

Reapply stolon application to all areas where the turf is thin or bare after the germination period.
