- Organic Worm Fertilizer for Plants - Worm castings are a 100% natural soil amendment and garden fertilizer for indoor plants and outdoor plants. Organic earthworm castings are rich in essential nutrients like nitrogen, phosphorus, and potassium, as well as trace minerals that improve soil conditions for better overall plant mass.
- 100% Vegan & Manure-Free - We raise our worms in a climate controlled facility and feed them a strictly vegan diet. The castings are meticulously screened to get rid of any traces of dirt, sand, or rocks, leaving you with nothing but pure worm castings for plants, unlike others who dilute their castings with synthetic ingredients or additives.
- Supports Microbial Activity - Using earthworm castings for plants encourages soil microbes that break down organic matter and convert nutrients into forms that plants can easily absorb. These microbes are crucial for increasing nutrient availability and building drought tolerance for a more balanced soil ecosystem.
- Excellent Water Retention - The humus in worm castings improves the soil’s ability to retain moisture, so you can rest assured knowing your plants are staying happy and hydrated. This reduces the need for frequent watering, so you can save water and promote more sustainable gardening practices.

The Earthworm Advantage: Your Essential Garden Buying Guide
Earthworms are nature’s tiny gardeners. They tunnel through soil, making it healthier for your plants. Buying the right worms makes a big difference in your garden’s success. This guide helps you choose the best worms for your needs.
Key Features to Look For in Garden Worms
When you buy earthworms, you need to know what makes a good batch. These features tell you if you are getting quality creatures.
1. Species Type Matters
- Red Wigglers (Eisenia fetida): These are the champions for composting (vermicomposting). They eat food scraps quickly.
- Nightcrawlers (Lumbricus terrestris): These worms burrow deep. They are excellent for aerating garden soil and improving drainage.
- European Nightcrawlers (Eisenia hortensis): A good middle ground. They handle both composting and light soil aeration well.
2. Worm Size and Activity
Healthy worms are plump and active. Look for worms that move quickly when you gently touch them. Small, skinny worms might be young or stressed. A good supplier ships worms that are actively moving and feeding.
3. Quantity Verification
Suppliers usually sell worms by weight (pounds) or count. Make sure you know what you are paying for. A reputable seller will give you an estimate of how many worms are in the package.
Important Materials: What Worms Need
The quality of the worms you receive depends on how they were raised. These ‘materials’ are crucial for worm health.
Bedding Quality
Worms travel and live in bedding. Good bedding keeps them moist and comfortable. Shredded newspaper, peat moss, or coconut coir are common. Avoid bedding that is too wet or smells sour. Wet bedding suffocates worms.
Moisture Level
Worms breathe through their skin. They must stay damp. The bedding should feel like a wrung-out sponge—moist but not dripping. Too dry, and they die quickly.
Temperature Control During Shipping
Worms are sensitive to extreme temperatures. Good suppliers use insulated boxes and sometimes ice packs or heat packs depending on the weather. Check reviews to see if others report worms arriving alive.
Factors That Improve or Reduce Quality
The way worms are handled directly impacts their usefulness in your garden.
Factors That Improve Quality
- Diet Before Shipping: Worms fed a varied, healthy diet before shipping are stronger when they arrive.
- Gentle Handling: Less shaking and rough handling means less stress on the worms.
- Proper Acclimation: Some sellers allow worms to adjust to cooler temperatures slowly, which helps them survive the trip.
Factors That Reduce Quality (Red Flags)
If you notice these things, the batch quality is likely low:
- Excessive Slime or Smell: A strong, foul odor means the worms were kept in overly wet or rotting conditions.
- Many Dead Worms: Receiving more than 5-10% dead worms upon arrival is a sign of poor shipping or unhealthy stock.
- Lots of Cocoon Casings: While some casings are normal, too many white, empty casings might mean the worms are old or have reproduced rapidly in poor conditions before being harvested.
User Experience and Use Cases
Understand why you need worms helps you choose the right type and quantity.
Composting (Vermicomposting)
If you want to turn kitchen scraps into rich compost (worm castings), choose **Red Wigglers**. They work fast in smaller bins and love vegetable waste. Users love them because they quickly reduce food waste.
Soil Improvement and Aeration
For lawns, vegetable patches, or flower beds, **Nightcrawlers** are better. They dig deep tunnels. These tunnels let air and water reach plant roots easily. Gardeners notice improved drainage after introducing them.
Bait and Feeding Pets
If you need bait for fishing or food for reptiles, **European Nightcrawlers** are often preferred. They are hardy and stay active longer out of water or soil.
10 Frequently Asked Questions (FAQ) About Buying Garden Worms
Q: Where should I put the worms when they arrive?
A: Immediately place them in their intended home—either a compost bin or directly into your garden soil, making sure the soil is moist.
Q: How long can the worms survive in the shipping box?
A: If kept cool (around 55-65°F) and moist, they can survive for several days. Open the box immediately upon delivery.
Q: Do I need to feed the worms right away?
A: If you are using them for soil aeration, no immediate feeding is necessary. If they are for composting, introduce small amounts of food scraps soon after placement.
Q: Are worms shipped in dirt?
A: No, they are shipped in specialized, moisture-retaining bedding like peat moss or shredded paper, not heavy garden soil.
Q: Can I mix Red Wigglers and Nightcrawlers in my garden?
A: Yes, you can. They occupy different soil layers, so they help aerate the soil at various depths.
Q: What is the best temperature for keeping purchased worms alive?
A: Most composting worms thrive between 55°F and 77°F (13°C to 25°C). Avoid freezing or extreme heat.
Q: How many worms should I buy for a small raised bed?
A: For a standard 4×8 foot raised bed, starting with one pound of worms is a great way to begin soil enrichment.
Q: Will the worms escape my garden?
A: If the surface soil becomes too dry or hot, they will burrow deeper or try to move. Keeping the topsoil slightly moist discourages them from leaving.
Q: What is the difference between worm castings and regular compost?
A: Worm castings (worm poop) are much richer in nutrients and beneficial microbes than regular compost. Worms pre-digest the material, making nutrients more available to plants.
Q: Should I buy worms certified organic?
A: If you are growing food and want to ensure the worms were raised without pesticides, look for organic certification. This guarantees a cleaner input material.
