When contacted by our clients 3 years ago, we were presented with some major challenges that are all too familiar along urban shorelines. Being asked by the client to “reclaim some order” was the task at stake but we also knew we were coming in as a third attempt to get a handle on the invasive and most troublesome, Reed Canary Grass in the past 8 years. This 2400 square foot site along the Minnehaha Creek had already been through controlled burns as well as multiple Round-up applications which proved unsuccessful. In addition to the invasive plant population that dominated, geese were also claiming this shoreline as their home which also created quite a mess.
This two part project over two growing seasons began on the upper bank with an organic sheet mulching process, followed by the second phase along the 65’ of shoreline where we opted to use a thick black plastic secured firmly with deep stakes that stayed in place through an entire growing season season. Due to the climate pattern for the last few springs that brought heavy rains through mid-June, we had to plan for high water eliminating the option to sheet mulch too close to the shoreline. While the use of plastics in the landscape is not ideal for our company other options were limited as we were working in a highly sensitive wetland buffer zone. (Continue reading below.)
