I find myself in the situation where I need to redo my raised vegetables and strawberry beds. I read What is a good alternative to pressure treated wood for raised beds? and Do chemicals leach from the sides of raised beds? which are excellent references and I was about to go with wood.
However, I have a huge heap of natural rocks (Griftstone and kind of granite and some others) which I got for creating, at some point in time, a dry stone wall in my garden which is a long slope.
I'm now wondering if I could use especially the griftstones to make a border of my raised beds. My main doubt is that the wall won't be closed. By definition there are holes and I'm afraid that water will dissolve the soil with time.
What do you think?
