Usually a lack of worm juice is one thing… You are not adding enough waste into your wormery. After all 96% of vegetable waste is water and so if you are adding waste there will be liquid draining. It’s not good to add a glut of waste at once for your worms – they need regular feeding so adding waste every couple of days will work best for your worm and your liquid feed production.
