Liquid Kelp

A natural fertiliser of concentrated cold composted bull kelp to support microbial activity.

Our Worm Cast Liquid Extract works very well on its own, however, the addition of a microbial food source such as fish and kelp will greatly increase the activation of the juice and assist with microbial adhesion to leaf surfaces.

Our suggested addition of liquid fish & kelp (50:50) to Worm Cast Extract is:

  • 1000L – 20L
  • 20L – 400ml
  • 10L – 200ml
  • 5L – 100ml

Liquid kelp has a shelf life of 2 years+ so can be kept for use with multiple worm juice applications.
