I have an existing fence which goes some way into the soil and we are cleaning and painting it then we plan on further raising the garden and lawn.
What are the best ways to protect the partially buried wooden fence from rotting?
There is already some rot but the posts are stable. Good ground clearance is not an option and most of my searching only reveals advice for fence posts although the are some threads about what is best for a garden bed. I am thinking garden edging could be retrofitted
Update: i think effective ground clearance is very unlikely (comment below). Even the neighbour's garden (lower) is against the base rail (also on their side). It isn't designed with proper clearance.
Update 2: the concensus is ground clearance, so after much hard work... images below
