Top Earthworms For Gardens Recommendations
- The Best Worms for Composting: Our Red Wiggler worms are harvested from worm beds that are decades old and may contain different earthworm species. Diversity is superior because they work all layers of the compost, not just the top few inches, giving you a better compost in a shorter amount of time

The ample supply of nutrients provided by each worm composter helps your garden to grow healthier plants and this valuable substance is all a result of your trash!
- Composting Worms Help the Earth: By feeding your food scraps to your worms for composting instead of throwing them away, you help to recycle nutrients and keep less trash in landfills. Using worm castings also reduces the need for harmful earth-destroying chemicals, instead relying on safe, organic production.

The Ultimate Buying Guide for Earthworms in Your Garden
Welcome to your garden’s best friend! Earthworms are tiny workers that make your soil healthy and strong. Buying the right worms is important for a happy garden. This guide helps you pick the best wigglers for your needs.
Key Features to Look For in Garden Worms
When you buy earthworms, think about what makes them good helpers. These features tell you if you are getting quality stock.
1. Species Matters Most
- Red Wigglers (Eisenia fetida): These are the best choice for composting. They eat fast and love kitchen scraps.
- Nightcrawlers (Lumbricus terrestris): These worms burrow deep. They are great for aerating large garden beds and lawns.
- European Composting Worms (Eisenia andrei): Similar to Red Wigglers, these are also excellent composters.
2. Worm Size and Activity
You want worms that are active and a good size. Small, sluggish worms might not be healthy. Look for worms that are actively moving when you check the package. They should look plump and moist, not dry or broken.
3. Quantity and Density
Sellers usually sell worms by weight (pounds) or count. Make sure the packaging clearly states how many worms you get per pound. A higher density (more worms per container) often means you start your project faster.
Important Materials: What Comes with Your Worms?
The worms themselves are the main material, but how they arrive is crucial for their survival.
1. Bedding Quality
Worms need a comfortable home for shipping. Good bedding feels damp, spongy, and smells earthy, not sour. Shredded newspaper, peat moss, or coconut coir are common, safe materials. Poor, wet, or smelly bedding can harm the worms quickly.
2. Moisture Level
Earthworms breathe through their skin. They must stay moist. The bedding should feel like a wrung-out sponge—damp but not soaking wet. Too much water suffocates them.
3. Temperature Control
Worms are sensitive to extreme heat or cold. Good suppliers use insulated boxes or add cooling/heating packs depending on the weather outside. Always check if the supplier ships based on safe temperature ranges.
Factors That Improve or Reduce Quality
A few things can make your worm purchase great or terrible.
Improving Quality:
- Reputable Source: Buy from suppliers who specialize in composting or fishing worms. They usually handle their stock better.
- Fresh Food Source: If the worms arrive with fresh, partially eaten food in their bedding, it shows they were fed recently and are healthy.
Reducing Quality:
- Pest Contamination: Check for unwanted guests like fungus gnats, mites, or soil mites. A few are normal, but a large infestation means poor farm management.
- Odor: If the package smells strongly of ammonia or rot, the worms were likely stressed, overcrowded, or kept too wet during transport. Quality suffers greatly then.
User Experience and Use Cases
How you plan to use the worms changes which type you should buy.
Case 1: Starting a Vermicompost Bin (Kitchen Scraps)
If you want to turn food scraps into “black gold” fertilizer, choose **Red Wigglers**. They stay near the surface and process organic matter very efficiently. Users report that a healthy worm bin reduces kitchen waste volume by half!
Case 2: Improving Garden Soil Health
If you want to loosen compacted garden soil and bring nutrients deeper down, choose **Nightcrawlers**. They tunnel deep, creating air pockets that roots love. Gardeners notice better drainage and stronger plant growth after introducing them.
Case 3: Fishing Bait
For fishing, Nightcrawlers are the standard choice because they are large and stay active longer on a hook. Red Wigglers are too small for most common fishing needs.
Frequently Asked Questions (FAQ) About Buying Garden Worms
Q: How many worms do I need to start a small compost bin?
A: For a standard kitchen-sized bin (about 10 gallons), starting with one pound of Red Wigglers is usually enough. They reproduce quickly if you feed them correctly.
Q: Can I just dig up worms from my yard to use in my garden?
A: You can, but store-bought worms are better for composting because they are usually specialized species (like Red Wigglers) that thrive in dense piles. Yard worms might leave your bin quickly.
Q: What is the best temperature range for shipping worms?
A: Most earthworms ship best when the temperature is between 45°F and 75°F (7°C and 24°C). Extreme temperatures can kill them.
Q: How long can the worms survive in the shipping box?
A: If shipped correctly with adequate moisture and bedding, they can easily survive 5 to 7 days. However, you should unpack them as soon as they arrive.
Q: What should I feed my new worms immediately after unpacking?
A: If they are for composting, start with small amounts of vegetable scraps or coffee grounds. If they are for the garden, place them in the soil right away and let them adjust.
Q: Are nightcrawlers good for worm bins?
A: No, Nightcrawlers prefer deep, dark soil. They often try to tunnel out of shallow compost bins, making them a poor choice for indoor composting systems.
Q: What does “casting” mean?
A: Castings are worm poop! They are the rich, dark, nutrient-filled material worms leave behind after eating. This is the valuable fertilizer you want!
Q: Should I add grit or sand to the worm bedding?
A: Yes, worms need small bits of grit, like crushed eggshells or sand, to help them digest their food. Suppliers usually include this, but you might need to add more later.
Q: What is the difference between composting worms and bait worms?
A: Composting worms (Red Wigglers) eat decaying matter quickly. Bait worms (Nightcrawlers) are larger and better at burrowing deep into soil, but they are slower composters.
Q: Can I use tap water to moisten the bedding?
A: It is best to use rainwater or aged tap water. Chlorine in fresh tap water can irritate or harm the worms’ sensitive skin, so let tap water sit out for 24 hours before using it.
