Tree Transplanting

There are 3 main ways that trees are provided: bare-root, rootball and containerised.

The pros and cons of each are summarised in the table below:

Pollution Tolerance

Trees planted in urban areas are likely to be exposed to the air pollution produced by motor vehicles. Pollutants include sulphur dioxide and nitrogen dioxide which can contribute to lower rates of photosynthesis in trees, resulting in lower growth rates. Choosing trees tolerant to these chemicals can mitigate the … Read More

Soil Compaction

As soil becomes more compacted from pedestrian and vehicular traffic, the oxygen content of the soil becomes lower and lower over time. The majority of tree roots inhabit the depth where oxygen levels are optimal; by compacting the soil the available rooting volume for the tree lowers, which can … Read More

Rooting Volumes

Trees within urban environments are often planted within small restricted spaces, with only a small amount of space available for roots to grow. Smaller available rooting spaces for trees means less access to water and nutrients, which can often be fatal for proposed trees.

The primary direction of tree roots … Read More

Over the next few weeks we will be discussing how a variety of factors need to be considered when specifying trees within residential schemes. These factors will include:

• Zones of Influence (Part 1)
• Drought Tolerance (Part 1)
• Rooting Volumes (Part … Read More
