## Top Soil Dressing 

Top soil ready to receive planting shall be given a dressing of manure at a rate of 5 kg/m². 

## Supply of Plants 

All trees, shrubs, grasses and other plants shall be supplied by the Contractor based on the Landscape design to be prepared by the Contractor and approved by Engineer. 

## Planting of Trees and Shrubs 

Prior to planting holes for trees and shrubs shall be prepared and filled twice with water. Plants shall be watered in their containers so that the soil and the roots are kept in a moist condition. Plants shall then be removed from their containers and their root ball complete with soil set in place and the holes backfilled and the plants firmly trodden in. Soil shall not be allowed to rise above the original container level and the ground level around the trunk or stem shall be set below adjacent ground to retain irrigation water. All species of tree and shrubs where required shall be provided with supports during planting. These shall take the form of timber stakes of adequate strength driven into the ground adjacent to the trunk or stem without damage to roots. Wide hessian strips shall be used to tie the plant securely but no tightly to the support. Where shrubs are to be planted in groups to provide ground cover, individual plants shall be spaced as follows:

## Irrigation 

After planting of native tree and shrub species they shall only be irrigated twice and thereafter only as required. Non-indigenous species shall be irrigated regularly until handover to the Employer. Grassed areas shall be irrigated immediately after planting and regularly thereafter until handover. Watering of grass shall be by night time sprinkler system. 

## Maintenance 

All new plants and grassing shall be maintained after planting. This shall take the form of irrigation, restacking, pruning, weeding, tilling, etc. to ensure sufficient growth is achieved by all. Once grassed areas are sufficiently established they shall be kept cut or mown to provide a uniform depth of growth. Edges of grassed areas shall be trimmed as necessary. All new plants and grassed areas shall be protected to prevent damage from workmen, builders plant, equipment and animals, by the use of temporary fencing or other suitable means. 

## Replacement 

Any trees, shrubs or areas of grass which fail to satisfactory growth or wither and die shall be replaced. The responsibility for the irrigation and maintenance of these replacement plants shall re- main with the Contractor until such time as they exhibit satisfactory growth.
