  • Author: Erin Hendrickson, RDN
  • Prep Time: 5 minutes
  • Cook Time: 24 hours
  • Total Time: 24 hours 5 minutes
  • Yield: 4 gallons 1x

Ingredients

Scale
  • worm castings (about 3 lb)
  • porous bag (an old t-shirt or pillow case will work well)
  • non-chlorinated water (preferably rain or filtered water)
  • 5 gallon bucket
  • optional: aeration system

Instructions

1. Make your ‘tea bag’. If using a t-shirt, tie up the bottom to hold the castings in place.

2. Add castings and secure the bag with a rubber band or string.

3. Fill the bucket with filtered or natural water, then add the tea bag of castings. If using optional aeration system, hook it up before adding the castings. Complete instructions here.

4. Allow the castings to steep in the water overnight or for around 24 hours.

5. Worm tea is finished when water has turned a brown color.

6. Strain the tea and transfer it to a watering can or spray pack. 

7. Water garden, lawn, or plants as directed. 

Notes

  • 5 gallons of worm tea is sufficient to cover an acre of plant life. A little goes a long way!
  • freshly brewed worm tea should be used as quickly as possible before healthy microbes begin to die off (within the first few hours)
