Article 1 — Description
Prepare the surface and provide and distribute temporary or permanent seeding for erosion control as shown on the plans or as directed.
Article 2 — Materials
2.1 Seed . Provide seed from the previous season’s crop meeting the requirements of the Texas Seed Law,
including the testing and labeling for pure live seed (PLS = Purity × Germination). Furnish seed of the designated species in labeled unopened bags or containers to the Engineer before planting. Use within 12 mo. from the date of the analysis. When Buffalograss is specified, use seed that is treated with potassium nitrate (KNO 3) to overcome dormancy. Use Tables 1–5 to determine the appropriate seeding mix and rates as shown on the plans. Include flower seeding mix in accordance with Table 5 with seeding mix shown in Table 1 and Table 2. If a grass plant species is not available by the producers, the other grass plant species in the se eding mix will be increased proportionally by the percentage of the missing plant grass species . If a flower plant species is not available by the producers, the other flower species in the seeding mix will be increased proportionally by the percentage of the missing flower species. Substitute species and rates require approval of the Engineer before being incorporated into the seeding mx. The rates listed in the tables are for drill seeding. All other methods of placing seed will require a 25% increase in rate. Table 1 Permanent Rural Seed ing Mix District Clay Soils Species, Percent, and Rate (lb.

2.5.2 Hydro Mulch . Use mulches that are on the Approved Products List . Submit one full set of manufacturer’s
literature for the selected material. Keep mulch dry until applied. Do not use molded or rotted material.
2.6 Tacking Methods . Use a tacking agent applied in conformance with the manufacturer’s recommendations or
by a crimping method on all straw or hay mulch operations. Use tacking agents as approved or as shown on the plans.
Article 3 — Construction
Scarify the area to a depth of 4 in. before placing the seed, unless otherwise directed. Use approved equipment to vertically track the seedbed as shown on the plans or as directed. Scarify the seedbed to a depth of 4 in. or mow the area before placement of the permanent seed mix when performing permanent seeding after an established temporary seeding. Plant the seed mix specified and mulch, if required, after t he area has been completed to lines and grades as shown on the plans. Apply fertilizer in accordance with Article 166.3., “Construction.” Grass seed, flower seed, and fertilizer may be distributed simultaneously during dry seeding operations, provided each component is applied at the specified rate. Do not combine fertilizer and seed in the same slurry during hydro mulch seeding operations. Apply half of the required fertilizer during the temporary seeding operation and the other half during the permanent seeding operation when temporary and permanent seeding are both specified for the same area. Water the seeded areas at the rates and frequencies as shown on the plans or as directed. Distribute the seed or seed mixture uniformly over the areas shown on the plans. Provide equipment with an agitator or method to maintain a uniform seed mixture during distribution. 2024 Specif ications 164 137 3.1. Planting Season .
3.1.1 Temporary Seed . Plant cool seeding mix September 1– January 31. Plant warm seeding mix
February 1–August 30.
3.1.2 Permanent Seed . End planting season for all Districts by May 15. Begin planting season for each District
based on the following. January 15. 1 (Paris), 10 (Tyler), 11 (Lufkin), 12 (Houston), 13 (Yoakum), 15 (San Antonio), 16 (Corpus Christi), 17 (Brya n), 19 (Atlanta), 20 (Beaumont), 21 (Pharr), and 22 (Laredo).

February 15. 4 (Amarillo) and 5 (Lubbock).
3.2 Broadcast Seeding . Use hand or mechanical distribution or hydro -seeding on top of the soil unless
otherwise directed. Apply the mixture to the area to be seeded within 30 min. of placement of components in the equipment when seed and water are to be distributed as a slurry during hydro-seeding. Roll the planted area using a light roller or other suitable equipment. Roll sloped areas along the contour of the slopes.
3.3 Straw or Hay Mulch Seeding . Plant seed in accordance with Section 164.3. 2., “Broadcast Seeding.” Apply
straw or hay mulch uniformly over the seeded area immediately after planting the seed or seed mixture. Apply straw or hay mulch in accordance with Section 164.3.6., “Straw or Hay Mulching.” Apply tack in accordance with Section 164.2.6., “Tacking Methods.”
3.4 Hydro Mulch Seeding . Plant seed in accordance with Section 164.3. 2, “Broadcast Seeding,” before placing
mulch. Apply mulch uniformly over the seeded area immediately after planting the seed or seed mixture at the following rates. Sandy Soils with Slopes of 3:1 or Less. 2,500 lb. per acre. Sandy Soils with Slopes Greater than 3:1. 3,000 lb. per acre. Clay Soils with Slopes of 3:1 or Less. 2,000 lb. per acre. Clay Soils with Slopes Greater than 3:1. 2,300 lb. per acre. Mulch rates are based on dry weight of mulch per acre. Mix mulch and water to make a slurry and apply uniformly over the seeded area using suitable equipment.
3.5 Drill Seeding . Plant at a depth of 1/4–1/3 in. using a pasture- or rangeland- type drill unless otherwise
directed. Plant seed along the contour of the slopes.
3.6 Straw or Hay Mulching . Apply straw or hay mulch uniformly over the area as shown on the plans. Apply
straw mulch at 2– 2.5 ton per acre. Apply hay mulch at 1.5– 2 ton per acre. Use a tacking method over the mulched area in accordance with Section 164.2.6 ., “Tacking Methods.”
