Tree species and location must be the first consideration in the practice of urban tree planting. Planting large trees in the wrong locations is counterproductive and will simply turn people against trees. However, we often see urban tree planting sites which could support larger species populated with 'whitebeam' or 'prunus', which really represent a lost opportunity. Big trees bring big benefits but they must be located wisely.

There is a direct correlation between what we provide the tree with below ground and the result we see above ground. Architects and engineers would never consider building a structure with inadequate foundations and yet many will routinely plant trees in tiny tree pits just a fraction of the size that the tree actually needs.

Wherever possible, plant trees in groups with shared soil space. They can then spread out happily amongst themselves and benefit from additional soil volume. One common method is the use of continuous trench planting and this is a very good way of providing adequate volume.

Consider planting trees in the following locations:

Build Outs In Road Schemes - One of the most demanding places for urban tree planting but one in which successful established trees have a huge impact. These can be used as part of traffic calming projects (thus fulfilling two roles in one), or simply parking delineation.

Verges - The most common area for urban tree planting.

Pavements - Demanding on the tree but can be achieved successfully with careful attention to tree pit design.

Car Parks - Again, a potentially hostile place to plant a tree but greatly beneficial in providing cool shade for vehicles in bright weather.

Plazas - These are the where trees can really have huge aesthetic and beneficial impact. There is nothing else that can be incorporated in these kinds of spaces that will confer the same degree of benefit.

Parkland - Few things can compete with established trees in a park setting. Try imagining a park without trees.

New Forest Pockets - Creating tree clusters in urban spaces and pocket parks is an excellent strategy to increase tree canopy for climate mitigation and adaptation.

Sustainable Urban Drainage Systems - Consider the use of urban tree planting as part of a storm water retention strategy. SUDS tree pit designs are now workable.
