Push or knock several sturdy poles firmly into the ground in two staggered rows. Leave a gap of about an arm's length between them, to be filled with prunings.
Lay the pieces of prunings sideways in the same direction, with the cut ends on top of each other, to create the base. Pile more branches and twigs on top.
Fill any gaps with leaves, which will slowly rot down, then pile on the rest of the stems, in the same direction. Top up with more material as you accumulate it all year round.
