Size and soil guide
Studies have shown the importance of providing trees with the necessary soil volume to allow them to grow through to maturity and reach their full potential for size and canopy cover.
Trees without an adequate volume of soil will generally under-perform (e.g. stunted growth or reduced lifespan) or force roots past their confines resulting in damage to adjacent infrastructure such as footpaths and kerbs.
The table below provides a guide for the required soil area in relation to the projected canopy (based on tree species maturity).
The projected canopy has been determined through an average relationship between tree height and canopy spread for broad spreading and pyramidal trees.
Tree species with a weeping or columnar form may need to be adjusted to better determine a more appropriate canopy spread.
Soil volume requirements are based on ‘Up by Roots-Healthy Soils and Trees in the Built Environment’ by James Urban.
| Size classes | Height (m) | Projected canopy size (m²) | Soil area (m²) and volume requirements (m³) | Minimum berm/planting area width |
|---|---|---|---|---|
| Small | 0 to 6 | 10.0 | 3.8 | 1.5m |
| Medium | 6 to 12 | 66.9 | 25.5 | 2m |
| Large | 12 to 20 | 185.9 | 70.8 | 2.5m |
| Very large | 20+ | 250.4 | 95.4 | 3m |
Engineering for trees
There are a number of designs and products available to aid in supplying trees with greater soil volumes. A few of these include:
- Soil cells: These are a plastic engineered product that can be installed below ground around where the tree is to be planted. The engineered product protects the soil from being compacted while providing the support required to construct footpaths and car parks on the surface.
- Root bridging: This is a process where a path or driveway is constructed in a way that leaves sections of the ground underneath uncompacted. Through doing this a space is left for tree roots to grow and pass through without causing damage to the above surface material.
- Structural soil: This is an engineered product that is made up of a mixture of stone aggregates and soil. Due to the stone aggregated, even as the soil is compacted down it is able to maintain voids that allow tree roots to penetrate the area and draw nutrients and water.
It is recommended that when designing around existing or proposed new trees a specialist is engaged. The council has a list of technician arborists(external link) with the necessary experience and qualifications to provide this advice.

Please note
The above list is under continuous development. Any planting on Council land or land that will be vested to Council must be approved by a Council arborist or landscape architect.
All planting must comply with the relevant IDS and CSS standards.
In addition to the above, do not plant any tree or plant listed in the National Pest Plant Accord, Canterbury Regional Pest Management Plan 2018–2038 plus subsequent amendments. There may be other trees and plants (such as dwarf flax), which are not acceptable to Council and that are not listed above.
Some woody shrub species, such as Pittosporum spp, Dodonaea viscosa, Leptospermum scoparium, Kunzea robusta, Myoporum laetum, Hoheria spp or trees such as Cordyline australis are not acceptable as specimen trees but may be used as garden shrubs. There may be some Prunus species acceptable to Council, such as those species less susceptible to silver leaf disease.
