Raised veg beds - how to build?
I am about to build some raised veg beds, and am wanting 2.2m by 1.4m. I had thought to simply get some ordinary planks of wood.
But how thick should they be? I do not want really thick ones, just wide enough so a nail won't split the wood.
Also, I was going for 30cm high. I presume it's better to but one plank rather than two on top of each other to get the height unless no option?
And is it best to nail them into each other or to get a post at each corner?
Where have other people got their raised veg wood planks and posts from?
