This is nothing to do with my frog question. I have a hedge on the north
side of my garden ( large garden but this bit of hedge is just by where I
meet with my only neighbor). This hedge is more of a high bank and seems to
be made up of soil with some stones in it ( a Cornish hedge of the old type
and no Cornish dry walling. Its not wide and I am not sure how stable it
is. There have been falls there before. I usually try to hold them back
with dry stone walling but that doesn't always work.

The thing that holds all up is the hedge which is mainly hazel.

However, one of the trees has rotted out and it came down in January. I
have pulled it out from necessity ( would hit the house otherwise. Now I
have a large gap there, little ground to do anything with and I ideally need
to do something to cover it over from my privacy and my neighbors.

It wont take posts for a fence ( not stable enough). I doubt I can get
another tree in there because its only about six inches wide at this point
and a sheer drop my side ( Its my bank by the way. I hold up my neighbours
land). Any suggestions as to how to cover it? Gap is about 10 ft wide.
Old mixed hedging either side of it. Mostly ivy and hazel but some
blackthorn in there.

Any advice appreciated.
