Prepare the ground by digging out strips of turf for the timber to fit.
Lay the timber in position to create a square or rectangle, the size you want. Check they are level using the spirit level.
Measure diagonally as well as the length and ensure the corners are right angles.
Use the rubber mallet to tap the wood so that the adjacent pieces are level and sturdy.
Then, drill through the end timbers at the top and bottom. Screw them into position ready for the next level to be added.
Assemble the next level of timbers and overlap the joints to help with the strength of the structure. Double check with a spirit level before screwing into place.
Add rubble or chippings to the bottom of the bed to aid drainage, then fill the bed up with topsoil and compost.
Once you’ve done this, you’re good to grow!
