Q. Who is Mr. Smarty Plants?

Title: Information on green roof demonstration site at Wildflower Center
Answered by: Nan Hampton and Mark Simmons

QUESTION:

I visited your green roof demonstration site and am interested in putting a green roof on a structure. There seemed to be at least two layers of growing medium in the planters; one layer looked like rounded pumice or rounded brick fragments and I believe it was below the drip irrigation lines and the other looked like a growing medium. Could you explain what each layer does and where I could get the stuff in bulk?

ANSWER:

Our expert, Mark Simmons, thinks the layers you are referring to are merely the gravitational settlement of the media (synthetic soil) following rain events. The composition of each of these media is proprietary; however, contacting the suppler Siplast may help. We are in the process of creating more infomation about this experiment as it gets set-up over the the next month or so. If you haven't seen it already, please visit our Green Roof Gardening page.
