raised beds

Hello, I am interested in making raised beds in the garden. I have not done this before, so I have a couple of questions: I am thinking of using wood due to cost, i.e. it is cheap. I see some people use pressure treated decking boards like these: http://www.wickes.co.uk/Wickes-Premi...-2-4m/p/101000 Is this the best timber to use? Is there a danger of the preservative leaching into the soil? I was hoping to grow some vegetables to eat and do not want to poison myself! Some web sites suggest putting a plastic sheet between the wood and the soil to prevent this contamination but other web sites do not mention it; is it necessary? What is the best way to screw four pieces of timber together to make a rectangular raised bed? I was thinking that I would need to sue a piece of 2x2 in each corner and screw into these. Half of the 2x2 could be buried in the ground to anchor it. However, is anchoring necessary: will the weight of the soil no hold it in place? Do I need to 2x2 at all, as I have seen some beds where the ends have been butted together and just screwed through. What is the best way of doing things? Thanks, Stephen. You could use western red cedar or thermowood to avoid the problems with preservatives. Thermowood is decking that been cooked and is fairly rot resistant. Sometimes B&Q have it. Red cedar is not cheap but pretty rot resistant untreated (not as much as teak though). |
