You have probably heard that earthworms (nightcrawlers) and red wiggler worms are soil magicians, able to enrich the soil and create extra quality compost, respectively.

However, you have probably also wondered how to keep worms alive.

That is especially true if you have already tried culturing them and failed and are now unsure what went wrong and how to begin anew.

In this article, you will learn answers to the following questions:

  • How to keep worms alive?
  • What is the difference between a nightcrawler and a red wiggler, and which worm does what?
  • What kind of setup do you need to keep worms alive – and thriving?
  • What food items to provide to have happy and healthy worms?

To start our journey, crawl this way, please – and don’t neglect to open the recommended links too!

What’s the Difference Between Earthworms and Wiggler Worms?

Despite looking similar and being phylogenetic cousins, nightcrawlers and red wigglers are not the same species.

What is vital for the rest of the story is that nightcrawlers and wigglers have different needs, so to give them the best chances of surviving and thriving, we have to consider them separately.

What Do Worms Need to Survive?

One of the main things all worms need to survive is their preferred habitat! The deep, dark soil offers worms everything they need for survival – including warmth, darkness, moisture, oxygen, protection from predators, and oodles of organic material to eat! As soon as you take a worm out of its preferred habitat, its odds of survival quickly plummets.

Like all other creatures, to survive and thrive, worms require food, water (moisture), and shelter (cover). However, as said before, the specific needs of the two species vary.

What Red Wiggler Worms Need to Survive?

Red wigglers are surface feeders that spend most of their time hidden in the litter or under some other cover at the soil surface, nibbling away at the decaying matter. 

They tend to aggregate around food sources, and although not social, they don’t mind each other’s company. Spending time at the surface means that they adapt to the warmer temperature range. 

All of these traits make them ideal for vermicompost bins. 

In short, red wigglers need some shelter in the form of surface cover or mulch, food, and substrate – special bedding that is part shredded paper, part worm castings, or humus.

What’s the Best Bin Set Up for Red Wiggler Worms?

Red wigglers are nearly always kept in a closed system – a garden bed, or more frequently, a vermicompost bin

You can find detailed instructions on how to make a worm bin on the EPA’s website.

Alternatively, you can consider shopping for ready-made vermicomposters – the designs are many!

What Earthworms Need to Survive?

One of the worst things for earthworms is when they get stranded atop a hard surface during a sunny summer day. Earthworms need deep, dark, undisturbed soil to reach their best potential. When exposed to hot, dry surfaces, the heat and lack of moisture can lead to a worm’s demise – quickly! Nightcrawlers are also easy prey to birds when unearthed. Birds love eating earthworms and nightcrawlers almost as much as trout, salmon, or largemouth bass love worms!

Unlike the wigglers, nightcrawlers are burrowers and will bury themselves several feet into the ground.

One of the reasons nightcrawlers dig themselves in is that they are trying to escape the surface heat. Nightcrawlers prefer a cooler climate than wigglers. 

As if that wasn’t enough, nightcrawlers are also solitary, so they require a lot more space than the gregarious wigglers. 

When considering everything, it’s not hard to conclude that earthworms don’t do quite well in closed bins. They can survive and do their work in a compost bin for some time, but setting up a colony that won’t die off at some point is challenging!

In short, earthworms survive best in a naturally-kept garden with healthy, spongy soil. 

Keeping and breeding them in a container is a story for another article. 

The good news is that open compost piles will naturally host earthworms. Those earthworms will venture above into the compost pile from the garden soil below, aerating and enriching your compost on the way. 

Compost piles can host both earthworms and red wigglers!

What to Feed Worms to Keep Them Alive

By this point, you are probably guessing that the nutritional needs of the two types of worms differ as well. 

Your guess is correct! 

Although, the difference is not so drastic. In theory, nightcrawlers can eat everything that the wigglers can eat – although they will munch it at a much slower pace.

What to Feed Red Wigglers?

what-to-feed-red-wigglers-with-worm-farm
I like to say that red wigglers are compost worms – and nightcrawlers are garden worms. Here’s why! Red wigglers love to munch on the organic matter and kitchen waste that you would otherwise chuck! Whether you have old fruit, tea bags, grains, yard clippings, or rotten veggies – red wigglers can turn that trash into garden gold – they love to munch on organic matter. If you add a composting system to your homestead, introduce some red wigglers to your arsenal!

Despite the idea that you can put just about any plant matter into a compost bin, the reality is a bit different, especially if you have a worm compost bin. 

While we don’t know if they have taste buds, it’s sure that red wigglers have their food preferences; some foods may harm them or even kill them, so you have to be careful.

Let’s Start with What Not to Add to Your Worm Compost Bin:

  • Meat, eggs, or dairy
  • Any fats or fat-saturated foods
  • Any citrus fruits or their peels
  • Potatoes and potato peels
  • Onions and onion peels
  • Pet poop 
  • Pesticide-laden garden clippings

I know that “never say never” is a popular thing to say, but please, never add meat or dairy to your vermicompost!

Unlike maggots, worms can’t handle dairy and meat. And not only will the animal food go smelly, but it will foster bacteria that can utterly annihilate your worm colony!

Now, off to the yummy stuff. Here are some food items your worms will likely appreciate!

An overview of the foods worms love, and the things you shouldn’t feed to worms. Good foods to feed your worms include vegetables, fruits, yard trimmings, and paper scraps. Don’t feed your worms animal feces, eggs, meat, fats, or citrus fruits.

What to Add to Your Worm Compost Bin?

  • Vegetables (carrot peels seem to be a fave)
  • Fruit peels 
  • Spent herbal tea
  • Squash
  • Cucumbers
  • Melon rinds
  • Coffee grounds
  • Paper, cardboard, and egg cartons

Also, you can add cereal-based food such as oatmeal, cornmeal, bread, and plain pasta. However, I’m not a fan of adding lots of this stuff to the bin because it goes moldy easily – especially bread!

However, if your worms like cereal-based food and they are numerous, they can work with it in moderation and works great sprinkled as a supplement. Still, I prefer leaving cereal-based foods to mealworms.

Choosing the right compost ingredients to add is a bit of trial and error. If you see that worms have left a specific item after a few days and have eaten the rest, it means that they are not fond of that particular food. You may want to avoid it next time.

If you keep worms in a bin, make sure you cover their meals with bedding or paper and cardboard cover to minimize odors and avoid attracting insects such as flies and wasps or critters such as mice.

The good news is that when wiggler worms like their food, they have helluva appetites, eating up to half their weight in a day!

More Worm Pro Feeding Tips:

  • Cut your scraps up or shred them into small pieces. That way, you ensure that your worms can process the compost scraps efficiently.
  • Most worms like to be left alone as much as possible. Feeding them once per week with the food scraps you’ve collected during that time is ideal.

How to Feed Nightcrawlers?

Earthworms are the best friend of gardeners and homesteaders who want nutrient-rich, aerated soil! Nightcrawlers love to dig deep in your garden – and they devour decaying leaves and organic matter – leaving behind worm castings which your garden soil loves! Nightcrawlers also act like miniature tillers – their underground garden tunnels make it easy for oxygen and moisture to access your garden’s soil. Talk about a helpful farmhand!

In a garden setting, if you keep your soil healthy, mulched with green or brown mulch, and amend it with compost regularly, the nightcrawlers in your garden soil will have plenty to eat.

Leaving the autumn leaves on the ground will also help the nightcrawlers have a steady food supply during the cooler months.

If you are still curious or want to experiment with keeping and breeding nightcrawlers in a contained manner, know that worm farmers often feed them chicken mash, cornmeal, or plain crushed oatmeal, misted with water upon sprinkling it on top of the worm substrate.

How to Keep Worms Alive? – One More Tip!

The most important take-away message is that keeping worms alive and using them in your garden and your compost is not such a big deal after all!

You have to consider the individual needs of each type of worm and follow a few critical principles outlined above. 

I wish your garden plants a lot of homemade, nutrient-rich worm castings!

  1. I want to start with worms directly in my raised garden bed. I’m wondering though… if I plant my (expensive) garlic in that bed will they eat the bulbs? Will they distinguish between what’s growing and what’s decomposing?

    Thanks!

    1. Hi Lorrie! The worms shouldn’t eat your garlic bulbs. Worms breathe through their skin, and the smell of an allium is just too stong for worms. Additionally, they should be able to tell a difference between what is growing and what is decomposing by the smell.

      So, you should be fine to plant your garlic! Happy gardening, Lorrie! 🙂

    1. Hi there Sarah, thank you for an interesting question!

      Unfortunately, worms cannot survive -10 degrees C (or 32 degrees F). Since they have bodies that are filled with fluid and they lack any sort of protection against the cold, they will sadly freeze to death as soon as the temperature goes below freezing – if they are directly exposed.

      In a natural environment, the worms survive by burrowing, since the deeper layers of the soil are always sustained well above freezing temps in temperate climates. Compost piles are different since the worms cannot access these well-regulated areas. Average, home-scale compost bins are sensitive to cold since they are usually not well-insulated.

      Even if the worms do manage to survive (since the compost pile may stay warmer than the outside environment if it’s large), they certainly won’t be active and won’t do their composting magic. They will stop feeding as the temperatures drop below their comfort zone (for the warmth-loving red wigglers, that’s below 13 degrees C or 55 degrees F).

      If you live in an area with true winters, you have two options when the wintertime comes:

    2. to let your worms go dormant (essentially “hibernate”)
    3. or to find a way to keep them warm and active during the wintertime.
    4. The first approach is usually favored by people who use vermiculture to compost their yard waste – in the wintertime, there is no new plant waste, and so the worms can rest. Still, it is important to keep your composting unit at temperatures above freezing at all times. A cool shed, garage, or basement are all good spots to put your composter during the dormancy period.

      If you have an outside heap, things are a bit trickier to control, especially if you experience a hard winter. Covering the pile with densely packed straw will help trap the warmer air and provide some insulation.

      On the other hand, people who use vermiculture predominantly to compost food scraps will want their worms to be active during the wintertime too. If you have some sort of modern light home composter, you can move it to a heated area of your home.

      Note that the vermicomposting process usually does not produce any foul odors and that some people even keep their vermicomposters in the kitchen! Still, for your convenience, it is better to opt for a room with less traffic. A heated basement, garage, or storage rooms are all valid options.

      Even the unheated garage can be used if you put the next to the warm wall (the one shared with your house) and if you drive a car regularly and park it there – the engine will release heat as it cools.

      If you have no other choice but to leave your vermicomposting operation outside, there are still ways to heat it.

      With large piles, you can apply extra feeding – carefully increase the nitrogen ratio – to boost the heat-producing bacterial activity characteristic of classic composting.

      Also, you can apply straw insulation or even the commercial seed starting mats, which works well for bins too. For more details on these strategies, you can read this very informative article:

      I hope this reply will help you to keep the worms thriving through the winter!
