Our house is bordered on one side by a set of old railway tracks, separated by a ditch. The tracks are being removed to make way for a walking path. I have trees lining my side of the ditch, but was wondering if there was anything in the way of a bush or shrub to deter trespassers.
The ditch rarely gets any sunlight, and often has standing water up to 2 feet for weeks on end. The ditch is around 12 feet wide, and my part runs about 150 feet. The bush or shrub should be think, so it's hard to get through. Does anyone have any suggestions on what to plant in there?
