Big Bio Worm Castings are a rich organic blend of nutrients & trace elements high in humates, beneficial bacteria and fungi. This product promotes healthy plant growth and soil conditioning. Produced locally in Melbourne.

Circular Foods divert food waste through vermiculture that would otherwise end up in landfills to create valuble worm castings and help close the loop on waste.

Worm castings are crucial to a healthy soil.  Some of the many benefits include:

  • Natural beneficial soil biology and nutrition
  • Provides greater plant resistance to pests and disease
  • Improves water holding capacity
  • Massive boost in plant and soil health
  • Certified organic

We recommend topdressing your soil with 1/2 to an inch of these castings right at planting with a light layer of mulch on top.  Water in with clean, dechlorinated water.

Use to make your own soil mix by adding 10 to 20 percent of total volume.

Make compost tea by adding 1 cup of castings to 20L of de-cholorinated water.  Ensure water is above 20 degrees celsius.  Mix 1 tablespoon of organic, unsulphured molasses and 20mL of fish hydrolosate such as Nutri-Tech Amino Max.  Bubble vigorously with an aquarium bubbler or high powered air pump for 24 hours.  Water old soil and tired gardens to rejuvenate soil biology and start growing healthy produce again.
