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. I built 3 large raised beds I do not like idea of wood being in contact with ground - especially ground you need to keep moist. I built mine out of 100mm concrete block ... then battened and clad outer face with wood and fitted wood 'cill' capping. More work - but will last a lot longer .... unless you use sleeps or similar ...decking won't last that long. I built 3 raised beds, opportunitstically as Wickes were selling decking boards very cheaply. 3 years down the line, they're showing no signs of rot at all. I used 2x2s in the corners and where the ground wasn't level, I lined parts of the insides with some old quarry tiles that were lying around in the garden from before my time. |
