Instead of normal soil, growing substrate must be used on green roofs because of its reduced weight. Growing substrate does not retain water as well as soil nor contain as many nutrients. Our experiment addresses whether the more drought-tolerant blackberry plant will thrive better and live longer in the growing medium on the green roof than the drought-sensitive raspberry plant. To test this, we planted two blackberry and three raspberry plants in a 1.5m x 2m plot on the green roof on the JAAC. We expect the blackberries to survive longer due to their drought-resistant qualities. Our research has the potential to help guide the choices made by future green roof planters when selecting edible plants.
