unsuitable or contaminated, use imported topsoil as specified above. 12. All plants which settle deeper than the surrounding grade shall be raised to the correct

level. After the plant has been placed, additional backfill shall be added to the hole to cover approximately 1/2 of the height of the root ball. At this stage, water shall be added to the top of the partly filled hole to thoroughly saturate the root ball and adjacent soil.

13. Container Removal: a. Do not injure root ball. b. After removing plant, superficially cut edge roots with knife on 3 sides.

14. Box Removal: a. Remove bottom of plant boxes before planting. b. Remove sides of box without damage to root ball after positioning plant and

partially backfilling. 15. Plant Tablets:

a. After the water has completely drained, planting tablets shall be placed as indicated below. 1) Two tablets per 1-gallon container. 2) Four tablets per 5-gallon container. 3) Six tablets per 15-gallon container. 4) Ten tablets per 24 inch box. 5) Fourteen tablets per 36 inch box. 6) Eighteen tablets per 48 inch and those box sizes which are larger.

b. Planting tablets shall be set with each plant on top of the root ball while the plants are still in their containers so the required number of tablets to be used in each hole can be easily verified by the City’s Representative.

16. Backfill a. The remainder of the hole shall then be backfilled with 2/3 native soil and 1/3

organic amendment thoroughly blended and tamped firm. b. After backfilling, an earthen basin shall be constructed around each plant. Each

basin shall be of a depth sufficient to hold at least 2 inches of water. The basins shall be constructed of amended backfill materials. Remove basin in all turf areas after initial watering.

17. Pruning shall be limited to the minimum necessary to remove injured twigs and branches, and to shape the plant material as directed by the City’s Representative. Pruning shall not be done prior to delivery of plants.

18. Staking: Staking of all trees shall be completed immediately after planting. All stakes shall be installed plumb and as indicated in Drawing details.

E. Planting of Groundcovers: 1. Groundcover plants shall be grown in flats or gallon containers as indicated on the

Drawings. Flat grown plants shall remain in those flats until transplanting. The flat's soil shall contain sufficient moisture so that it will not fall apart when lifting the plants.


2. Groundcover shall be planted in straight rows and evenly spaced, unless otherwise noted, and at intervals called out in the Drawings. Triangular spacing shall be used unless otherwise noted on the Drawings.

3. Each rooted plant shall be planted with its proportionate amount of flat or container soil. Plantings shall be immediately sprinkled with water after planting until the entire area is soaked to the full depth of each hole.

4. Care shall be exercised at all times to protect the plants after planting. Any damage to plants by trampling or other operations shall be repaired immediately.

F. Mulch Cover: All groundcover, perennial, and shrub beds shall be dressed with a 3 inch layer of mulch, where slopes are not steeper than 2:1.

G. Hardpan Conditions: 1. Where hardpan exists, whether it is in the form of caliche or other impervious clay, and it

is within the top 2 and 1/2 feet of soil, use powered equipment to break through completely at each tree location to allow drainage and root growth. Remove hardpan at least 1 - 1/2 feet greater than the root ball diameter of tree. Backfill with soil mix as specified.

2. Where hardpan is within the first 12 inches of soil, it shall be completely penetrated for all shrubs.

H. Lawn 1. Sod
