Our garden border is defined by a steep bank about 4m high, into a small river - not quite a cliff but so steep you would struggle to climb it. The river bends into our border at one point which raises questions of erosion over time.
We're in the north of England in a fairly wooded area so the bank here is in partial shade.
I wondered if there are particular plants or trees which would be good to encourage to grow at the top and on the slope of the bank, which will help bind the soil together and reduce erosion risk?
Equally, if there are things which would be detrimental - whose roots might break the bank up, or whose weight/height make them likely to be blown down and the bank damaged?
