Composting in the Worm Farm is easy and odour-free. The kit comes with trays where the worms transform food scraps into vermicompost so that you can harvest the worm casts tray by tray, a sump where the liquid worm tea is collected and a secure lid.

The compost worms produce is really rich - often referred to as "Black Gold". You can use as a rich base for potting compost or as a fertiliser when planting out and as a top dressing for your pots and planters. Worm tea is a liquid fertilizer containing a lot of rich nutrients and enzymes that help your plants grow and prevent pests. You will never have to buy liquid feed again.
