Excess plants delivered, but not planted, shall be turned over to the Project Manager at the end of the planting phase.

Planting requirements:

• Plant in weed-free prepared planting beds.

• Over-excavate each planting hole by at least 1.5 times the width of the plant and 3 inches deeper than the depth of the plant to be planted.

• Assure planting holes accommodate the full depth of the root mass, no “J-root” planting or twisting of the root mass to accommodate small holes is allowed.

• Pre-water hole to pack and moisten soil before planting plant (per the Quality

Standards below).

• Backfill holes after planting. Pack soils around plants to minimize air pockets.

• Within 6 hours or less after planting, apply water to each plant to provide moisture and to ensure no macro or micro air pockets exist in the planting hole. Watering should be done with three gallons of water per plant, spaced over several time intervals to allow water to penetrate and fill in around the newly planted plant.

• Park provided water may be obtained on site.

• Create a “shelf” at each plant so that the downhill and uphill edges of the plant are equally covered with soil.

• All empty planting containers shall be returned to Presidio Nursery.

• No additional soil can be brought into the park.

• After nursery grown plants have been install, a 2-3-inch layer of mulch wood-chips will be evenly distributed over the entire planting area to aid with moisture retention and wind damage to plants.

The species of nursery grown plants, with abbreviations used in Figure 1:

• Each plant must be watered using enough water to reach the lowest roots.

• Water shall be applied in short intervals to allow water to move through the soil column and prevent washing topsoil away from root crown.

• Each plant must be individually using hose or bucket. Flood and broadcast irrigation or use of a lawn-type sprinkler is not permitted.

Water will be provided by the government at a location near the planting site, $65/1,000 gallons. The contractor shall use clean equipment free from herbicides, pesticide residue, and soils/ invasive plants seeds.

5. Temporary Storage: The Contractor shall ensure that plants are stored in areas protected from wind and full sun and that container soil is thoroughly moistened. Plants should not be delivered to site prior to day of planting. Plants cannot be returned to nursery once removed.

CONTAINER PLANT INSTALLATION

1. Weed Prevention Protocol: Ensure all vehicles, gear, tools, equipment, personnel (e.g., clothing, boots, laces) Personal Protective Equipment, etc.

2. Planting Specifications: All container plants shall be planted in accordance with the following specifications:

• Immediately prior to planting plants shall have thoroughly moistened soil.

• All planting holes shall have vertical sides with roughened surfaces and be a minimum of one and one-half (1.5) times the diameter and a minimum of 3 inches deeper than the depth of the plant’s container.

• Damage to surrounding native plants shall be minimized.

Excessive digging, trampling and piling soil removed from planting holes is not allowed.

• Any roots wrapped around the sides of the containers shall be pulled loose from the root balls. Plants shall be planted with the roots untangled and laid out in the planting holes to promote good root growth and prevent the plants from becoming root bound.

• Roots shall be adequately protected from the sun and/or drying winds. Plants shall not be removed from their containers until immediately before planting. The container shall be removed in a manner that does not damage the root ball or plant.

• After excavation and before planting, the planting holes shall be filled with water. Holes shall be allowed to drain thoroughly before planting to reduce settling.
