Each farm gets about 10 litres of scraps every three weeks. Once a month he empties the bottom tyre of one of the farms and distributes the compost and worms on the garden or adds it to more mature compost heaps. The empty tyre is placed back on top ready for more scraps. Ray also grows bumper tomato and courgette crops by feeding them leachate or worm rum gathered from the farms and diluting it eight parts to one with water. Wormeries are easy to maintain.
Worms like to be kept damp and in the dark, and warm in winter and cold in summer.
Put the farm close to the kitchen door, for convenience, and the worms will happily devour all your food scraps.
