Adding worms to our productive beds increases the nutrients available to the plants. A vermicomposting bin is an easy way to encourage their activities and build more biodiversity.
Set a bin in each bed, with dampened shredded cardboard at the base, several good handfuls of composting worms, like red wiggles, add an inch of good trimmings etc (avoiding the likes of citrus and onions) then cover with woodchip.
Aim to top up their food supply each week, you will see the level drop as they are active.
The worm casts etc will feed the plants, the population will grow and get active through the beds, opening up airways, and devouring any crop and drop or lasagne layers.
Worms : One of our best friends.
