Construction Specification SD-484 Dormant Wood Plantings (Cuttings, Stakes, and Posts)
Scope The work shall consist of furnishing all labor, equipment, and material for site preparation and planting the designated species of trees and shrubs in the designated areas as specified. The work includes following specified plant establishment procedures for specified dormant woody cuttings, stakes, and/or posts.
Materials Materials will be as indicated on the drawings.
Plant materials must be healthy, native species, or other species adaptable to the planting site. Plant material diameter and length shall be as follows:
| a. | Dormant cuttings must be 1/2 to 1 inch in diameter and 12 to 24 inches in length. |
| b. | Dormant stakes must be 1 to 3 inches in top diameter and 18 to 36 inches in length. |
| c. | Dormant posts must be at least three inches in top diameter and long enough to reach saturated soil. Minimum length is seven feet. |
Material preparation Material preparation must follow proper procedures to assure survival. Except as specified on the drawings, materials must be selected from young, vigorous, healthy stock located within 50 miles of the planting site. Make clean cuts and avoid split ends. Trim side branches to leave the bark ridge and branch collar intact. Butt ends shall be tapered to facilitate driving and proper planting orientation. Top ends must be cut flat to allow driving and to distinguish tops from butts.
Material storage and protection Collected and prepared plant materials must not be allowed to dry out. For best results, plant materials the same day they are cut and prepared. Materials must be kept moist during storage, transport, and all other times prior to planting. The butt end of plant materials (one foot length minimum) must be kept submerged in water until planting.
Material certification Prior to planting, the contractor shall furnish the Natural Resources Conservation Service inspector a written certification (signed and dated) that the plant materials meet requirements of this specification. The certification must include the following as appropriate:
| a. | For commercial plants - species and/or varieties and the number of plants, condition, size, age, source of production, and date supplied to the contractor (signed and dated by the supplier). |
| b. | For native harvested materials - the species and location of origin (section, township, and county,) the date the material was cut (supplier signed and dated). |
| d. | Dates and locations plant materials were stored. |
| e. | The name of the project where the plant material is to be planted. |
Planting Site Preparation Prior to planting, the site must be prepared as shown on the drawings.
Planting Dormant plant material must be planted in unfrozen ground between October 15 and May 15 - spring planting must occur before the plant buds have broken dormancy.
Plant materials must be planted with the butt end down. Set the butt end of the plant material at least 12 inches into a moist soil layer. Plant Material must be planted as deep as possible (at least 40 percent of total length below ground,) but at least 2 lateral buds and or terminal bud scar must be above ground.
To avoid plant damage in most soils, holes should be created before insertion or driving of materials.
Good contact must be established between the soil and plant material (tamp if necessary,) but avoid excessive damage to the bark, especially stripping. When driving dormant stakes or posts, care must be taken to avoid splitting. Cut four to six inches from the tops of stakes and posts damaged by driving.
Stakes and posts located in water must extend at least 12 inches above normal water level.
