A garden composter has a longitudinally extending cylindrical drum which is mounted to a support frame and can be rotated relative to the support frame about an axis of rotation of the drum. The drum has at least two load openings formed in a cylindrical wall portion between two end wall portions and removable closure caps for selectively closing the load openings. At least one partition divides the drum into a number of chambers disposed side by side along the longitudinal axis. Each chamber communicates with a respective load opening. The partition has a fixed portion coupled to the drum and a relatively movable portion. Each portion has at least one flow control partition opening and the movable portion can be moved so that its associated flow control partition opening may be selectively brought into and out of registration with corresponding flow control partition openings in the fixed portion.
