I will be using the square foot gardening method for this raised bed. Has anyone built a raised bed before and lined the inside of the timber with a damp proof membrane or even heavy duty plastic bags, so as to protect the timber? I am painting the outside with black exterior paint, but I don’t want to paint the inside, to keep chemicals away from the soil etc. Thanks all.

In my opinion ou shouldnt put plastic inside the bed on the sides as the soil can sort of 'sweat' if that makes sense and damage the soil structure. Leave the bare wood and paint it outside. Be better for your plants long term.

It stands to reason that the timber will last longer when the earth inside won't be up against it. As you also, I have hinged lids that have a hooped polytunnel attached to the lid (hoophouses). Just a tip, I put hinges on both sides - using 4" butt hinges with a removable centre pin - so that the lids will open from either side, as the hoophouses are 4' wide.

tom1ie wrote: » Great idea. I was planning on putting a set of boot lid struts on the hinged side but new ones are costly and old ones from a breakers yard are quite powerful so always want to push the lid open so I’d need a latching system for the bed. I’ve set mine up to have a double layer of greenhouse plastic with an air gap in between. How are these working out for you?
Samson1 wrote: » Yes, I looked at the idea of struts too but ruled them out when I hinged both sides. I also set mine up to allow for adding a second layer of greenhouse plastic at a later date. However, they are working fine with a single layer of 800 grm ? greenhouse plastic, and get up to a maximum daily temperature of about 48C, and a minimum overnight temperature of 11C to 13C for the past week. My biggest fear was a lack of ventilation, I initially was going to cut small vent holes in the plastic in either end, but finally went with propping the lids open about 9", and dropping down 12" of enviromesh all round and securing that, and tying the lid down with bungee cords (between 2 handles). It allows a good airflow and the tomato plants went in in the past week or so and they seem happy out so far! I used rough red deal 9" x 2".

I’m levelling the ground and putting down the weed barrier (which I’ll be stapling to the bottom of the raised bed) this morning. Then I’m hoping to get my soil in today. (1/3 compost 1/3 peat moss 1/3 vermiculite). If the weather stays somewhat reasonable I might get my square foot grid in and some of the tomato plants.

Its about 2.2 metres long and 66 cm wide and 30 cm (12 inches) in height from the ground to the top of the frame. Is the most effective way of planting vegetables digging into the existing ground soil, and adding top soil and compost to the top of the box? How much compost would I need- I read somewhere that it should be a 60% soil-30% compost ratio. Haven't finalised exactly where to place it in the garden yet either- is a suntrap or shelter better? Am I better off sectioning off each segment with mesh to "crop manage" so to speak? Thanks in advance.

No bending or stooping, no slugs or animal damage. A chainsaw some nails and a hammer and it's a quick job. I've used scaffold boards on the edges for some to make a deeper bed.
