Benefits of Green-tree Intensive Roof Garden Substrate
Good levels of fertility
Has the ability to sustain plant establishment and growth.
Excellent aeration properties
Creates holes into the soil to reduce air, water and nutrient compaction to enable these elements to reach the roots.
Good water holding properties
Water holding capacity is controlled primarily by soil texture and organic matter. This soil features a large surface area which enables it to hold more water.
Lightweight compared to standard soils
This is critical for roof gardens as lightweight soil decreases density and enhances drainage capabilities.
A typical pH of 7.8
pH 7.8 makes this soil an alkaline soil, ideal for a wide range of planting. It contains sodium, calcium and magnesium that builds strong stems and leaves.
