Project Partners in Action - What can we learn from science? - trees wellbeing, longevity with BlueGreenWay

Researchers at the Warsaw University of Life Sciences (SGGW), led by dr hab. inż. Marzena Suchocka, prof. SGGW, have developed an innovative anti-compaction stone-soil mix called BlueGreenWay, designed to support tree growth even under heavy urban surfaces like sidewalks and streets.

Unlike traditional substrates that get crushed and starve roots of air and water, BlueGreenWay stays porous, holds up to 0.31 m³ of rainwater per m² under pavements, and creates space for roots to access oxygen and moisture — helping trees live decades longer.

This nature-based solution improves water retention, reduces heat islands, and lowers tree planting and maintenance costs. As cities look for green infrastructure that works alongside hard surfaces, this mix demonstrates how thoughtful engineering can co-exist with urban ecosystem services and support tree wellbeing.
