Worm castings tea can be a great addition to your garden or indoor plants. But like any new thing that you’re adding into your life, there are some potential problems with using worm castings for tea. So it is important that you know what these risks might be before jumping right in.
What Are Worm Castings?
Sometimes called vermicompost or worm poop, worm castings are a rich soil amendment with high concentrations of nutrients that are beneficial for plants. They’re perfect for mixing into potting soil when starting new plants in order to provide a well-rounded diet for them. They also work great as a natural plant fertilizer or soil cover on top of barren ground that needs some life breathed into it.
Worm castings are also pretty good at breaking down organic waste from the kitchen or garbage, making them a highly useful part of any compost pile. There’s not too much in the way of downside to worm castings, and you can always add more if necessary.

So What’s the Real Downside to Using Worm Castings for Tea?
- Essentially, it’s just a matter of time. When making tea with worm castings, you know there will be some additional time involved because you have to let them sit around in there for a bit before brewing up the final product. Worm tea is made from worms, which can take anywhere from a few weeks to several months to fully process.
- And it takes a bit more time for the tea to brew up, because you’re adding living creatures into it. And that means your tea will have a different taste, smell and texture than any tea you’ve ever used before.
- In fact, some people claim that worm castings make great herbal infusions or teas that are ideal for drinking on a regular basis if they include fruits or vegetables in them. So there’s nothing wrong with using worm castings as an ingredient in your daily cup of chamomile tea (or whatever else you prefer).
How Do You Use Worm Castings for Tea?

The most basic way to make worm tea is to add about a half cup of castings into a gallon of water. Then you let the whole thing sit for about 24 hours, stirring briefly a few times in the process. That’s all it takes to brew up some worm tea.
- If you want to get more elaborate with it, then you can use one of the several compost aerators on the market these days. These work like regular aerators on kettles and pots, but instead of clogging up and getting dirty like regular ones do, compost aerators are reusable and dishwasher safe.
If you’d rather use your own special formula for worm castings tea blending, then go for it. There are some pretty good recipes out there for making worm tea or aerated compost tea using just about any kind of fruit or vegetable peels that you can think of.
If you’re trying to be really thrifty, then composting might be a better option. You can make your own castings at home by mixing together old and new compost in a ratio that works best for your own set up, then letting it all sit around and break down before using it in the garden or making a batch of worm castings tea from it.
Alternatively, you can buy a bag of premade compost tea that is already pretty well broken down and ready to go. It might not be as thorough as if you made your own, but it’s usually pretty cheap and gives you the added benefit of already being mixed up and ready to go.
Worm Castings Tea Safety Concerns
One thing you need to keep in mind is that worm castings are quite dirty. After all, they’re made from human feces, so there’s a little bit of nature’s waste mixed into every serving. It’s a good idea to be careful with your hands, and especially so when handling castings. Wear rubber gloves in particular when working with this material.
Worm castings tea can also have some pretty strong smells to it, so you’re going to want to avoid breathing too deep in the vicinity of your wormy tea brewing. If you do get a whiff of possible infection in there, then you should wash off any excess worm castings and contact a medical professional if necessary as soon as possible.
Any other health concerns? Worm castings might be loaded with certain microbes that can help keep some pathogens at bay (though they are considered safe). There’s also the possibility of insect eggs or larvae in your tea, though this is pretty rare in most cases and only happens when you’re not careful about what you’re putting into your brew. Worm castings can also be a bit slimy, so make sure that it doesn’t get on any sensitive surfaces like the countertops and sink.
What Do Worm Castings Tea Taste Like?
Worm castings are chock full of minerals and good microbes, so they might have a bit of an earthy taste to them when used as fertilizer on its own. When you take the time to make worm castings tea, this earthy taste is going to permeate the final product and make it a bit more strong. Used in small enough doses though, this can actually be beneficial for your plants by giving them an extra boost of nutrients that might otherwise be missing.
Worm tea can also have a slightly earthy smell to it. This is nothing too bad, but you might notice it more than other teas if you try to do a blind taste test. It’s just the smell of the castings and whatever else you put into your brew. Some people like this though, so if you can handle it, then go for it!
So Is Worm Tea Safe?
Yes! As long as you follow the directions that come with any worm tea or worm casting supplement that you purchase and make at home, there’s really no reason to worry about safety with worm castings tea. Just be careful with any incidental safety concerns that might come up along the way, and you’ll be just fine.
Worm tea makes a fun activity to do with your kids as well, and you can enjoy some delicious tea made from worm castings while getting some hands-on time with your children while they learn something new and exciting in the process. It’s a pretty simple recipe to follow too, so no worries there. Just don’t let any of it get on or near anything else.
How to Make Worm Castings Tea

It’s no secret that worm castings tea is a beneficial natural drink. It’s filled with plant chlorophyll and other nutrients that can help you stay healthy. Plus, it is said to have many amazing health benefits!
But where do you get the castings from? That answer might not be so obvious, but it doesn’t need to be difficult. Most gardeners know about worm casting tea because of this article! It advises how to make this yummy beverage in your own backyard! All you need to do is involve the worms in your yard by supplying them with coffee grounds or other organic waste material.
There is a bit of a catch to all of this, though. The worms aren’t the only things that need the organic waste. Others who need organic waste are the larvae of mosquitoes, their food source! This can be good news or bad news depending on your perspective. Good news means no mosquito larvae in your worm castings tea! Bad news means that you have some pests to deal with, but at least you’ll have an easy way to eliminate them for good!
Unfortunately, if you rid yourself of mosquitoes, you’ll need other ways to fight off these pests. That’s why we’ve also included information on how to get rid of mosquitoes inside and outside your household. This article will teach you how to protect your home from these pests and how to keep them out of the yard!

- The first step to making worm castings tea is digging a hole. Now, if you’re just getting started with your worm castings tea, it might be hard to dig the hole in your backyard. This is why we recommend that if you’re just getting started with worm castings tea that you start with a small bed garden and a few worms in there.
- After you have dug your hole, take some time and make sure it is big enough for the worms. The worms should be able to easily move around in their new home and not feel or look like they are cramped. Also, when you are finished, the worms and their bedding should be approximately 1- 2 inches below ground level
- Once the hole is big enough for the worms, add dirt to make it around 4 inches deep. Then add a couple of handfuls of organic materials such as coffee grounds or garbage. These organic materials will sustain the worm population and reduce odor.
- After you add a few handfuls of organic material, take your shovel and dig out a big enough space for your worms to live in. Make sure that space is about 2 feet deep.
- After you have dug out a 2 feet wide, 2 feet deep space, fill it with organic materials. Then, add some dirt if necessary to make it over 4 inches deep. Next, add your worms. You can purchase worms from a local garden shop or you can give them away to neighbors and friends to get them started.
- Now that your worms are in their new home, cover the hole with more dirt making the total soil level 4 inches below ground level.
It is said that the production of these worms is best done with temperatures between 55 and 80 degrees Fahrenheit. The ideal area for worm castings tea gardeners to set up their worm castings production site is on a patio or back porch. This will provide an optimal environment for the worms while also giving you easy access to the worm castings tea production site.
Worm castings tea can be made year-round as long as enough worms are present to procure the amount of nutrients needed for the tea production process. When there are not enough worms in one specific area, worm castings tea can still be made by digging up some dirt from another area in your yard and adding it to the worms’ area. This is sold as a good idea to ensure that tea production doesn’t stop.
How Do Worm Castings Compose?

- It takes anywhere from a few weeks to several months for composting material to break down completely into perfect castings. The castings formed by worms are the result of this process.
- What kind of castings will you get from your worm tea? The castings that you get from worm tea are made of all the organic matter in your tea with the eggs, larvae and other insects that might be in your composting material. You’ll also get some additional organic matter from steeping or other additions that your recipe might call for.
The best thing about worm castings is that they’re ready to use right out of the bag! No need to let them sit around for months, producing an unknown amount of bacteria, helping things rot at an even quicker rate and leaving a lot of unwanted nastiness behind. Worms are pretty environmentally friendly when it comes down to it.
Worm casting tea is a pretty simple process, but it can take some time to get your bags of worms started. You’re going to want to start collecting your own worm castings once you’ve gathered up a few dozen or so worms, then choose some easy-to-start composting material and start mixing it all together in an old coffee can. It’s very important that you bury this material loosely so that the worms can dig down into the composting materials easily, plus they’ll find places to hide when they need to rest between feeding (they’ll most likely burrow down through the bottom of the coffee can).
You’ll want to keep these worms in the dark until they become comfortable with their new environment. If you don’t, they’ll burrow quickly back into your castings and leave you with a lot of work to do. When you see your worms starting to make homes for themselves in your compost, then it’s time to start feeding them!
This is where your worm tea will come from. Once you’ve got your tea brewing, just be sure to give the worms some time to get used to their new diet and habitat before you start harvesting any castings for use as a tea additive or fertilizer. Then all you need to do is reap the benefits of your hard work!
If you want to make worm castings tea, all you need to do is follow the directions on the bag and compost them up as normal. Worm tea is a pretty simple process and not too much more complicated than composting basics by any means. You just need a few worms and some black or green tea. This worm casting kit isn’t going to make your life any easier though because it doesn’t have a collection bin or worm bin included. They don’t even come with a bag of caecotrophs (the worm making material) either.
If you want a quick and easy way to make worm tea at home, then this is something to consider. However, if you want to gather your worms and compost up tea at the same time, then you might need to do some research on worm bins or other ways of making your own castings from home. Just remember what kind of material you’ll be putting them into and be careful as always!
How To Mix Worm Tea Into Your Soil

Gardeners have been using worm castings for ages as a natural fertilizer for their plants. These days, it’s becoming more popular than ever with foodies and people who are looking for an alternative fertilizer. It takes a bit of time to get to know each strain of worm, however, the process becomes much easier with time.
There are two major methods that you can use to mix your worm tea into your garden soil. The first is to add it directly, while the second involves using plastic bags and storing your tea in there as you go along. Follow these instructions carefully then see how things work out for yourself with either method.
- Mixing your worm tea directly into your soil is the easiest way to do things (though not necessarily what you want). Simply mix up small amounts of tea at a time. Remember that worm tea starts out as a nitrogen source, so don’t add too much to the area where you want your plants to grow! Stir your tea carefully and well with a shovel or garden fork. Leave it sitting in the areas where you’re planning on planting for around two weeks. You can leave it in longer if you like, as this will be enough time for the worms to eat all of the food sources that you gave them (they won’t really feed on much else after about two weeks).
Once your tea is totally “eaten” up, you can let the worms crawl away and continue their lives. They’ll leave behind their castings for you to replace in the garden however you see fit. You can use it on your plants in the future, or simply add more composting material and try again!
- If you don’t want to add worm castings directly into your soil, then you can use a plastic bag to store them. To do this, simply use one of your castings balls as a template and cut out the shape with a pair of scissors. Take your bag and lay it out flat on the ground then put some soil in it and press it down firmly with your hands. Add the worm tea to the center of this makeshift bin then bury it up to its sides in soil. The top needs to be left open so that you can collect any runoff or leaks later!
Let it sit for two weeks, much like you would if you were simply planting directly into your garden soil. Then it’s time to collect your worm tea and use it just like you would your garden soil or other composting materials!
- The final method is to use plastic bags with holes in them. Depending on the size of the bag, you can add up to 10 liters of worm casting tea into each one. Fill it up with all of your worms and then place the bag under some tarp or a large piece of plastic. This will let any runoff water out easily without affecting the worms who are nesting inside.
Leave your bag to sit in the sun for two to three weeks, then get ready to collect your worm tea and use it as you would any other type of fertilizer!
