Worm Casting Tea Recipe: How to Make Liquid Fertilizer from Vermicompost

Vermicomposting creates nutritious compost using worms—easy (worms do the work), great for plants. Result: worm castings (worm poop), loaded with plant nutrients.

Worm casting tea: steep castings in water like tea leaves. Result: all-natural liquid fertilizer, dilute and water plants. Here's how to make it.

How to Make Worm Casting Tea

Basic method: Scoop handfuls of castings (no worms!) into 5-gallon bucket, fill with water. Soak overnight—morning liquid = weak brown color.

Application: Dilute 1:3 tea to water. Use immediately—goes bad after 48 hours. For neater steeping, make tea bag from old t-shirt or stocking.

Enhanced Worm Casting Tea Recipe

More complex but more beneficial:

• Add 2 tbsp sugar (unsulfured molasses/corn syrup) → feeds beneficial microorganisms.
• Submerge fish tank bubbler, brew 24-72 hours → aerates, greatly increases microorganisms.

Watch for bad smells. Putrid odor = anaerobic microbes. If smells bad, don't use.
