This raised frame will need to be supported by stakes driven into the ground. These stakes hold the upper and lower frames together and ensure the weight of soil in the raised bed does not push or bulge the long sides outwards. Measure the sides to determine the position of the securing stakes, we have chosen to position the takes 2.5ft from each end.
Drive the crowbar deep into the ground in the chosen position for each stake, as close to the inside edge of the frames as possible. Work the crowbar backwards, forwards and around to enlarge the hole. If you encounter an obstacle with the crowbar such as a large stone, you may either reposition this stake or cut the stake shorter. Drive all the stakes deep into the ground with a sledgehammer.
