By November, we had succeeded in removing so many invasive plants from the slope area that I became concerned about water just rushing down the slope, with no plants to stop its progress.
There weren’t that many “good” plants remaining, after we took out the invasives. There were about 3 willows, and a few other smaller shrub/trees. However, the ground only had smaller plants, like tiger lilies and some lower-growing perennial invasive plants that I (fortunately) had not identified yet.
We had to think creatively. I drove many miles to an Agway, to pick up a roll of landscape jute. It turns out, this stuff is wonderful for a slope! We’re also fortunate to have neighbors with laying hens, who shared some of their wonderful compost. I layered the compost with leaves, some unfinished compost I had, some wood chips, etc., “lasagne” style, then covered the whole area with the jute, tacking it down with staples.
