The Tiger worm (Brandling worm/ Manure Worm Eisenia fetida) is very good at the rapid processing of Organic waste into nutrient rich compost, we often get asked which type of worm is best for composting, in short the answer is probably a mixture of both dendrobaena worms & tiger worms as both types have a huge appetite & both species have a slight difference in ‘needs’ so combining both dendrobaena & tigers in the wormery (they only breed with their own species & live quite happily together) ensures the wormery works efficiently.
