<br />bottom of the hole to the top of the ground to avoid drying out until the enfire
<br />planted area is thoroughly watered and the soil soaked to the full depth of
<br />each plant hole. Wafer stream shall not cause damage to planfing hole or
<br />plant. Keep exposed roots wet by means of moist sawdust, peat moss or burlap
<br />at all times during planting operation. Repeat wafering as often as necessary
<br />to keep the ground moist but not soaked well below the root system of the
<br />plants.

<br />PALM TREE PLANTING
<br />PART 1 -GENERAL
<br />1.01 WORKINCLUDED
<br />Palm tree installation
<br />1.02 ESTABLISHMENT, GUARANTEE AND MAINTENANCE
<br />Per Specification Section 02900.
<br />Contractor to guarantee palms against the vascular disease Penicillium
<br />(Gliocladium) vermaeseni, the fungus Fusarium oxyseorum, and the roof disease
<br />Phytophora and similar vascular infections for a period of five (5) years.
<br />1.03 RELATED WORK
<br />Contractor: Minimum five (5)yearsexperience in supply and installation of palm
<br />trees.
<br />Foreman: Minimum five 15)-years experience in related work shall be on site at all
<br />fines.
<br />1.05 REFERENCE STANDARDS
<br />ANSI 60.1 - American Standards for Nursery Stock.
<br />MAG Specification Section 795
<br />1.06 PRODUCT DELIVERY, STORAGE AND HANDLING
<br />A. The Owners Representative or Landscape Architect may be available to review and
<br />tog palms at place of growth and may review palms upon delivery for conformity, to
<br />the specifications. Travel to nurseries out of the metropolitan Phoenix areas, when
<br />requested by the Contactor will be paid for by the Contractor.
<br />B. In lieu of non -local nursery review, the Contractor may elect to provide photographs
<br />with a person adjacent to each palm for preliminary review. Such review shall not
<br />impair the right of review and rejection during progress of fine work should the palms
<br />not meet specifications.
<br />C. The Contractor must certify that the palms are free of disease prior to shipment.
<br />D. After tagging of the palms, remove all thatch from older leaves and cut back all
<br />resulting stems to within two (2) inches of the base of the hunk. The crown of the
<br />palm shall be reduced per standard nursery practice prior to shipping. Use soft rope
<br />(organic twine) to tie remaining fronds to protect crown bud. Do not permit fronds
<br />to become damaged by means of restraint.
<br />E. Exercise extreme caution while pruning palms to prevent spread of vascular
<br />diseases. Dip pruning tools in a sterilizing agent before beginning pruning and before
<br />moving from one palm to another. Do NOT use any chain type saws for pruning
<br />operations.
<br />F. AlaMce-type crane, a telescoping type crane or a specially designed fee crane is
<br />acceptable for off-loading and lifting of palm frees. Undersized equipment (i.e.
<br />tractor) shall not be used for these purposes. For transporting, the hailer used shall be
<br />long enough to avoid damage to the heart of the palm. Loading and unloading of
<br />the palm must be accomplished with the aid of nylon or fabric sling/straps with a
<br />minimum width of four (4) inches. Do not use any other type of off-loading
<br />equipment such as metal cables, chains, or ropes that may damage the palm frees.
<br />Excessive starting or hunk damage due to improper offloading will be cause for
<br />rejection of the palms at the project site. Daring loading and off-loading the palm is
<br />to be balanced in the sling to avoid the rootball of the palm from dropping and
<br />hitting the ground. Any palm handled in an unacceptable manner will be rejected
<br />and is to be removed from the site.
<br />G. If the palms are not planted the day they arrive at the project site, the crowns and
<br />roof ball shall be protected from the sun and from reflected heat from fine ground.
<br />Avoid stoning on an asphalt surface.
<br />H. Covering material must allow air movement so that heat doesn't build up under the
<br />covering. Do not use plastic or rubberized tarpaulins. Palms may not be stored for
<br />more than thirty-six (36) hours. Do not stack palms, but lay them in a single layer on a
<br />flat surface. Covered rcafbalh must be watered lightly every couple of hours.
<br />PART 2 - PRODUCTS AND MATERIALS
<br />2.01 PAWTREES
<br />A. Palms shall be free of dead or dying fronds, with all fronds of a normal size and color.
<br />B. Palms to have straight hunks. The petiole layer shall have been removed by hand
<br />using the "classic cul"harvesting method showing a diamond shape hunk
<br />appearance.
<br />C. Selected palms shall not vary from adjacent palms by more than one (1)-Foot. It is
<br />Unacceptable to plant the roodiall deeper than the original soil line of me palm.
<br />D. All palms shall be healthy, vigorous and well foliated prior to pruning and show no
<br />signs of disease. They shall be free of disease and of insect pests, eggs or larvae.
<br />They shall also have well developed root systems, All palms shall be free from
<br />physical damage or adverse conditions that would prevent thriving growth.
<br />E. Verify that all field -dug palms contain an adequate rootball to guarantee successful
<br />transplantation. Do not install palms that have damaged rootballs.
<br />F. A maximum of Twelve inches (12) of aenal )air) roots should be visible when the palm
<br />tee iz planted in the ground.
<br />2.02 ACCESSORIES:
<br />A. Clean, washed river sand )CONCRETE SAND WILL BE REJECTED)
<br />B. Frond Ties: Minimum of one-ha8(1/2)-inch diameter soft sisal rope capable of
<br />maintaining fronds in tied position for one (1)year
<br />C. Fungicides: Soil Drench Subdue by CIBAGIEGY
<br />D. 12-48-8 wafer -soluble terfilizer.
<br />PART 3 - EXECUTION
<br />3.01 SEQUENCING AND SCHEDULING
<br />Coordinate delivery of palms with planting operations to avoid on site storage longer
<br />than thirty-six (36) hours. Planting delays will result in rejection of the palms.
<br />3.02 PREPARATION OF THE SITE
<br />Protect existing plant material, walls, pavements, and other site amenities from
<br />damage. Verify and maintain all clearance requirements for both overhead and
<br />underground ufilifies.
<br />3.03 EXECUTION OF PLANTING
<br />Lay out palms of locations as shown on the plans. The Owners Representative will
<br />check location of palms In the field to venty exact position before planting begins.
<br />The Contractor shall be responsible for accurate layout where palms are to be
<br />pre -planted to permit the installation of site improvements around them, The
<br />Contractor shall be responsible for the protection of these palms while work is taking

<br />drench and an ORNALIN (1 /2 ounce/gallon) drench.
<br />Clean, moist Over sand shall be added to the bottom of the tree pit and tamped or
<br />waahjeffed prior to planting of the palm.
<br />Install drainage and viewing pipes) in each pit to assure wetting of the whole root ball
<br />and to enable monitoring and viewing of the free pit chamber. The vents shall be four
<br />(4) inch diameter perforated PVC, with sufficient length to extend to the bottom of the
<br />tree pit Wrap pipe with filter cloth. Loosely cap fops of pipes and glue bottom caps.
<br />The top caps are to be held above finish grade and painted to match the adjacent
<br />surface material. Do not backfill drainage or viewing pipes.
<br />Backfill shall be two-thirds (2/3) clean, washed Over sand amended with one-third (1/3)
<br />native soil. In areas where soils are heavy in mliche additional sand may be added.
<br />The slower the water percolation rate, the deeper the layer of sand that must be used
<br />beneath the root balls. During and after placement of the palm, moistened sand shall
<br />be thoroughly tamped as Al is being added to assure stability of the free.
<br />A six (6)-inch deep swale shall be made around each palm tree to provide
<br />water holding capability.
<br />Apply a two (2)-inch layer of mulch (per planting plans) in all palm tree water basins,
<br />being careful to not allow mulch to fall into drainage or viewing pipes.
<br />After planting, the crown buds of all the palms shall be within one P)-foot of the
<br />designated palm tree height above finish grade.
<br />After planting, drench soil with the fungicide "SUBDUE" per Manufacturer's
<br />recommendations by flooding the planting basin. Reapply as often as label permit
<br />throughout the maintenance period. Fertilize palms with a wafer -soluble, 12-4
<br />solution at a rate of eight (8)-pounds per 100 gallons.
