Last year we didn’t grow that much veg because we started late in the season and we didn’t really have anywhere to bring on seedlings etc but this year we want to grow a lot more so we needed another raised bed.
We decided to build it in this unused part of the allotment that had an old plastic composter and a pile of rubbish left by the last plotholder.
We are basically extending an existing bed which was really interesting because I needed to remove the blocks forming the end of one of last years beds and it gave me a chance to see a cross section of a year old no dig bed.
You can see that the cardboard and the manure has completely broken down into a lovely rich soil and the original topsoil from the allotment has been drawn up into the raised bed presumably by worms.
You can see the original soil level and the lighter coloured soil has been drawn up a good 4 inches.
I started by cutting the grass and weeds with the shears, I left all the cuttings in the bed as they will rot down and add to the fertility of the soil.
I then added a good layer of wilted nettles
Next I put a good 6 inches of well rotted manure.
And a very thin layer of grass clipping. It is important not to put too much grass on at one time or they wont rot down quickly enough.
And then a couple of inches of compost which gives a nice layer to plant into.
So this is the finished bed complete with canes for the runner beans.
The bed was given a good drenching between each layer.
This bed will be planted over the next week or so
Here is a great video on how to build a no dig bed.
