Good morning all. Every year we make wormeries with layers of soil and sand but the results are often not good. Occasionally we get terrific trails and mixed up layers but most times there is very little movement at all. The wormeries are the ones on a wooden frame with 2 sheets of Perspex about 3 cm apart. Our soil layers are about 3-4 cm and our sand is 1cm deep. The layers are lightly tamped down and we leave grass cutting and old leaves etc on the top. About 10 worms are introduced and then we put black covers over the apparatus. Does anyone have any handy hints ?!
