By the end of this lesson: you will gains understanding on the depth of bedding depending on the wormery’s specific purpose.

Give worms enough bedding to move through and retreat into. In a tray system, do not overfill so much that the tray cannot function, but do not be stingy either. A thin layer of bedding gives very little protection. A good working layer gives the worms options.

Breeding Bins:

These want slightly less height in the bedding.  Afterall you don’t want romantic worms to be tunnelling about, you want them focusing on the task at hand.

European Nightcrawlers:

These larger worms seem to prefer deeper bedding.  Perhaps it’s due to their size and mobility.  It’s also likely due to them wanting to burry deeper during hot periods.  So, if you have these don’t scrimp on the depth of the bedding.

European Nightcrawlers really want about a 10 – 12″ depth in the bedding which can be quite a bit if you have a large box and a lot of worms.

Tiger worms want slightly less for a normal castings bin at around 6 inches.

Top Tip – Caution, If you go too deep with the bedding, thinking you will do all the work now and save time by making a massive bed.  Well, the worms don’t go that deep and the reason why is moisture will trap there and most likely the oxygen will be too low to make it acceptable.
