Just moved onto new property, it has a good? dam but there are numerous small trees growing on the walls, mostly seedlings up to 2-3 metres tall but quite spindly. I have been told by a couple of people to cut these trees down as they will eventually damage the structure. Lots of scribbly gums in the paddock (acid sulphate soil area) so I wouldn't be denuding the area.
Any knowledgable advice would be welcome.
