Tree Pits, Why, How – The Basics

Tree Pits – What are the options and why Soil Support Cells provide the best long-term solution.

Hard landscapes present unique challenges to the installer but this need not detract from the project of integrating good quality mature trees into the built environment with speed and ease.

Good Quality Soil Fill at Archway Gyratory

Planning policy around the world provides increasingly stringent guidelines to the implementation of green infrastructure projects and associated tree planting in retrofit and new build contexts.  Remember Trees are forestry plants.  As soon as we forget this simple fact we are likely to make mistakes when planting them in town and city environments.

The approaches below are often what we see around the world:

  • Dig a hole and hope for the best
  • Lack of aeration/irrigation
  • Structural Soils
  • Low volume tree pits
Yet another failed scheme

Make a Difference! 

High volume tree pits with enough space and soil will deliver the best results!


  • Using a soil support system with an associated group of root management, aeration and irrigation products
  • Ensuring that soil cells are filled with uncompacted, good quality soil
  • Soil Volume, critical that there is enough quality soil for the tree roots.
  • Root management keeps tree roots in intended rooting zones and away from utilities, paved surfaces, and other infrastructure
  • Correct installation
  • Space, allowing for projected tree growth – design for the long term!
