Choosing a tree for a Lower North Shore property.

Choose for the mature tree

A young tree at a nursery can hide the space it will need later. Begin with its mature height, canopy spread and roots, then compare those dimensions with the available space.

Allow for buildings, boundaries, overhead lines, underground services, driveways and sight lines. A species that fits one Lower North Shore property may be unsuitable a few streets away.

Read the planting spot

Check sun, wind, drainage and soil where the tree will actually be planted. Harbour exposure, sandstone, fill and compacted urban soil can create very different conditions within the same suburb.

Think about how water reaches the spot and where it drains. Leave practical access for establishment and later maintenance.

Decide what the tree should do

Useful goals include shade, screening, habitat, seasonal interest or replacing a removed tree. Rank those goals before choosing a species.

For screening, several smaller plants may suit the boundary better than one large tree. For shade, consider where the canopy will fall as the sun moves and the tree matures.

Check local planting requirements

Council guidance, a development approval or a removal decision may specify replacement planting. Heritage and biodiversity rules can also influence the species and planting position.

Use the current documents for the address. If the property adjoins bushland or contains sensitive vegetation, seek suitable ecological advice before changing the planting or clearing plan.

Plan for establishment

Plan the soil preparation, watering, mulch, protection from damage and early formative care. Leave enough room for the tree's mature form rather than relying on repeated heavy cutting to keep an unsuitable species small.
