9.1      GENERAL

Supply the scheduled number of plants to the quality, size and health in accordance with this specification
and Plant Schedule. Plants shall be secured in sufficient time to ensure they achieve specified sizes and
quality for the Contract. The Superintendent must be informed immediately if any difficulty is encountered in
procuring the plants on the nursery site at which they are to be stored, and clearly labelled as being for this
project. The allocated plants must also be made available to the Superintendent to be inspected at all
times.

Photographic evidence of all species is required 4 weeks after Contract has been let. Photographs must
contain at least two plants / trees per species including a measuring staff or other measuring devices
illustrating height and spread of individual species.




9.2      SPECIAL REQUIREMENTS

Attain all plant stock from a QALI registered supplier with an Australian Standards Approved Quality
Assurance System.

The nurseries location must be situated within 100km radius of site and inspection of all plant stock shall
take place at one location only. Alternatively, the Contractor shall reimburse the Superintendent for time
and travel to inspect the plant material.




9.3      EXCAVATING FOR PLANTING

9.3.1    PLANTING AREAS

Excavate a hole for each plant large enough to provide not less than 200mm of topsoil around the root
system of the plant, or as shown on the Drawings.



9.3.2    PLANTING OF TREES

Excavate hole a minimum 300mm wider than the rootball and deep enough to accept a minimum 200mm of
topsoil below. Break up the base of the hole to a further depth of 200mm, and loosen compacted sides of
the hole, as necessary to prevent confinement of root growth to the hole. Backfill with imported topsoil,
lightly tamp and water to eliminate air pockets.




9.4      PLANTING

9.4.1    GENERAL

Set out plant material in positions and quantities as shown on planting plans unless otherwise directed. If it
appears necessary for plants to cover the area more uniformly, or for similar reasons, notify the
Superintendent for instruction and direction.

Planting holes shall be prepared not more than twenty four- (24) hours in advance of planting. A slow
release tablet form of fertiliser is preferred, 'Agriform' or equivalent. Apply tablets at the rate and depth of
the manufacturer's recommendation. Water plants in containers immediately prior to planting.

Install plants as shown on Planting Plan and associated details. Ensure the topsoil level of the plant root
ball is 20mm below the finished surface of the soil surrounding the hole, backfill as required.
