Worm Tea Fertilizer

$8 for 1 gallon

Worm tea is a nutrient-rich liquid fertilizer and microbial inoculant that supercharges plant growth. It introduces beneficial bacteria, fungi, and essential nutrients (like nitrogen and potassium) to your soil. This boosts root development, improves water retention, and helps plants naturally suppress pests and diseases.

How to Use Worm Tea

Use it Fresh: Your worm tea is most powerful right after brewing! Use it immediately to deliver the highest concentration of active, healthy microbes straight to your garden.

•Soil Drench: Pour the tea directly into the soil at the base of your vegetables, flowers, or houseplants. It delivers microbes straight to the root zone.

•Foliar Spray: Put the tea in a spray bottle and mist the leaves of your plants (top and bottom). This coats the foliage, actively helping to deter pests and combat common fungal diseases.

•Frequency: Apply to your plants once every 1 to 2 weeks during the active spring and summer growing seasons

Worm Castings

Out of stock

Currently out of stock. Text if you want to be notified when castings are available again.

Benefits of Worm Castings

Nutrient Rich: High in easily absorbable nitrogen, phosphorus, and potassium.
Soil Booster: Improves soil aeration, structure, and water retention.
Microbial Shield: Adds beneficial microbes that suppress plant diseases and pests.
Gentle: Safe for all plants because it will never burn delicate root systems.

How to Use Worm Castings

Potting Mix: Blend 1 part castings with 4 parts potting soil for indoor plants.
Top Dressing: Scratch 1–2 inches into the soil surface around existing plants.
Seed Starting: Mix 1 part castings with 3 parts seed starting mix for strong roots.
Transplanting: Place 1–2 tablespoons directly into the hole before inserting the plant.
Lawn Care: Broadcast 10 pounds per 100 square feet to rejuvenate thin grass.

Build Your Own

Worm Bin setup:
1.) Buy or build a worm bin. I like to use 27gal Costco tote. Simply add air holes near lid ridge.

2.) Add Bedding. My favorite Bedding is shredded cardboard mixed with worm castings. I can provide the shredded cardboard for free and I can also provide you with the casting ($5/gal). I suggest starting off with 4 gallons of castings.
  A.) Soak the shredded cardboard in water and wring out the excess water (shoot for damp sponge consistency)
  B.) Mix castings with moist cardboard

3.) Start off with at least 1lb of worms (anything less gets tricky with feeding and will take a long time for the population to grow large enough to be productive).

Alternative setup

Worm tower

A worm tower is a simple in-ground composting option for garden beds: bury a perforated pipe, add food scraps from the top, and let worms move in and out through the holes.

  • Uses a short PVC pipe with holes drilled through the buried section.
  • Food scraps go in from the top and stay below a lid.
  • Worms feed inside the pipe and spread castings into the surrounding soil.
  • Good option when you want composting directly in a raised bed instead of a separate bin.
What is vermicompost?

Nature’s superfood for plants.

Vermicompost is nutrient-rich organic fertilizer made when red wigglers break down food scraps, dry leaves, and other plant waste into dark, crumbly, earthy-smelling castings.

How it is madeOrganic waste → earthworms → worm castings → vermicompost for soil and plants.
What it looks likeDark brown to black, fine and crumbly, moist but not wet, with an earthy smell.
Why gardeners use itSupports stronger roots, more flowers and fruit, better soil structure, and beneficial microbes.
How to use itMix 10–20% into potting mix, top dress soil, or soak vermicompost in water for a mild liquid feed.

Care guide

How to feed and care for worms.

Keep it simple: moist bedding, small buried feedings, shade, and patience.

Feed

  • Fruit and vegetable scraps
  • Coffee grounds and filters
  • Crushed egg shells
  • Small amounts at first

Avoid

  • Meat, dairy, grease, and oily food
  • Too much citrus or onion
  • Salty food
  • Large piles of fresh scraps

Moisture

Bedding should feel like a wrung-out sponge. If it is dry, mist it. If it is soggy, add shredded paper or cardboard.

Location

Keep bins shaded and protected from heat. Worms do best when the bin stays cool, dark, and breathable.

Temperature note

Red wigglers are composting worms, not deep-soil earthworms. They do best in a mild, shaded bin. If the weather is hot, feed smaller amounts and keep the bin out of direct sun.

Pocket feeding

Feed one small spot at a time.

Pocket feeding means burying scraps in one corner or small area of the bin instead of spreading food everywhere.

  1. Dig a small pocket in the bedding.
  2. Add a handful or two of chopped scraps.
  3. Cover completely with bedding or castings.
  4. Next feeding, choose a different pocket.

Why it works

  • Reduces smell because food is buried.
  • Makes it easy to see if the last feeding is gone.
  • Helps avoid overfeeding.
  • Gives worms a place to move away if food heats up or gets too acidic.
Quick fixes

Most worm-bin problems are easy to correct.

Bin smells bad

Usually too much food or too much moisture. Stop feeding for a few days, bury exposed scraps, and add shredded cardboard or paper.

Fruit flies

Bury food deeper, cover the top with dry bedding, and avoid leaving sweet scraps exposed.

Food is not disappearing

Feed less and chop scraps smaller. Worms eat softened, decomposing food faster than large fresh chunks.

Worms try to leave

Check moisture, heat, and acidity. Keep the bin shaded, bedding damp but not soggy, and avoid big acidic feedings.
