Crafting Worm Castings Tea: A Guide for Gardeners

Remember, this 'tea' is exclusively for your plants, not for human consumption!

Worm castings tea is a marvelous tonic for plants of all stages, from delicate seedlings to mature foliage. It replenishes nutrients lost in potting soil for young sprouts and rejuvenates older plants. This tea is a boon for every plant, irrespective of age.

Here's your step-by-step guide to creating worm castings tea:

  1. 1. Start with a 5-gallon bucket of water (use 1 gallon for a smaller batch).
    •  Rainwater or unprocessed water is ideal for immediate use.
    • If tapping into municipal water, let it rest for a day to allow chlorine, harmful to beneficial microbes, to evaporate.
    • Avoid softened water as its high salt content can harm plants.
  2. Mix in 16-32oz of worm castings (3-8 oz for a gallon). Use a coffee strainer to contain the castings if you prefer. Alternatively, simply add the castings directly to the water for dissolving, especially if you'll filter the tea later.
  3. For an optional boost, add two tablespoons of unsulphured molasses. This feeds the tea's micro-organisms and enhances its stickiness, helping it cling to leaves even after rainfall or watering.
  4. Oxygenate the tea for 24-48 hours. This can be done by stirring multiple times daily or using an air stone and fish tank pump. Use the tea within 4-12 hours after aeration for peak microbial activity.
  5. Apply the tea by pouring it around the plant base for root absorption, or strain it (using a nylon hose to prevent nozzle clogging) and spray directly on the plant’s leaves and stems.

Regular bi-weekly use of worm castings tea encourages stronger, healthier plant growth. Watch your garden flourish with this nourishing liquid!
