Tips on Storing Worm Tea

There are a lot of things that you can do with worm castings; and one of them would be to make tea out of worm poop from red wrigglers, and nightcrawlers. To find out more, you should read a few facts in this article about tips on storing worm tea, and more. Worm compost tea is basically made through a brewing process. It’s created by immersing the castings of worms into the water (the castings are usually enclosed in a cloth bag, and is tied so nothing seeps out from the bag as soon as it is submerged in the water). The nutrients and the other good bacteria that’s contained in the castings are then released into the water. It’s when the water is aerated that the microorganisms grow and multiply in number (an oxygen-rich environment is produced). This worm tea dilution then becomes your liquid organic fertilizer.

So, how do you exactly make worm compost tea?

Well, you’re going to have to prepare a bucket that can hold a gallon, and then some dechlorinated water. You’ll also need an aquarium pump, some tubing, an air stone, and of course, your worm tea bag. And as soon as you’ve prepared all these supplies, you may then fill your bucket with some dechlorinated water. You’re also going to have to soak the worm casting tea bag; and have the bucket of water aerated using your tubing material that’s been attached to the aquarium pump, and air stone (dip this inside the bucket). Let this whole process work for about 24 hours (do this overnight). Now, as the worm tea is being brewed, the soluble materials and the nutrients that come with it, are then dissolved into the water. As soon as your 24 hours is over, you may use the brewed worm tea immediately  (you’ll know your tea is ready when the water starts to turn into a light amber color). You should also be informed that you’re also going to have to use the tea from red wigglers or nightcrawlers castings right away. It’s advisable to collect it and use it at once because it will turn anaerobic later on; and you wouldn’t want any beneficial microbes dying away and getting wasted. So, if you don’t want to use it just yet, you may follow a few of these storing tips:

  1. Do not store the brewed worm tea recipe inside a PET bottle, unless you want the beneficial microbes to die right away.
  2. It’s best that you store it inside a container, with a lid that loosely covers it, or without a lid. This is important since the good microorganisms in the worm tea solution needs air. If you fail to do this, your tea may soon smell horrible; and your plants and soil won’t be able to fully appreciate the benefits that come with your worm tea.
  3. To sum it all up, you’ll really need to consume it within 24 hours.

But basically, you may use worm tea instantly to spray directly on your plants, soil, and even on your vegetable produce. It’s that easy to apply, and that safe to use. It simply becomes a protective layer, especially for your plants. And if getting tips on storing worm tea isn’t enough information for you, you may want to try making worm tea soon after.

    I’ve been storing my worm tea in tool soda containers and then I store them in the house and use them in about 2 weeks diluted with water. So am I just wasting my time as my worm tea is in a closed container? Also will the worm tea hurt the plants if I do not dilute it with water. I worm tea come straight from the bottom of my worm bin and it is already a dark amber color. Any tips on storing my worm tea would be highly appreciated.
    I have my worm bin in the house because it’s been freezing outside. Would it be okay to put my worm bin in the shed and put a portable heater out there?, right now my worms are doing good but I really do not want them in the house if you know what I mean

  • Is there any harm if the brewing process is extended to say 60hrs, with aeration, instead of 24hrs surely this will increase the bacteria count especially if temperatures are say less than 20°C (69°F)

  • My 20 week old pup has drank up to 500ml of worm tea. This was in a plastic water bottle for 6 months. Should I be concerned?

    Thank you for your help xx

  • I have containers of worm tea and castings. I have kepted them in container up to now. Should I put it on my gardens.

  • rob mcintyre says:

    if you do not aerate your tea and you keep it in an open container for say a week or two can worm tea organisms stay dormant and then aerate before using it

  • Awesome site, just wondering about drying out worm casting for harvest. I noticed people dry them out which is fluffy.
    I have read that if you dry them out that the bacteria will die, so drying them out will lose all the beneficial bacteria? but if i don’t dry them out they are kinda muddy.

    • Hello Paul;

      Worm Castings need to be kept cool and moist for the microorganisms to stay alive. You can store them in a bucket with a loose fitting lid, in a cool dry place and they will stay alive for up to 4-6 months. You should not dry them out or let them get overheated.

    • Hi Rob,

      I so apologize you never received a reply! The worm tea will need aerated frequently. Without the oxygen the microbes in the tea will die. It is best to use it as quickly as possible.

  • morning uncle,i want to store my worm tea in a closed container,what can i put in my worm tea so that it not blow up the their any asid that i can put in tea to prevent that,and wil it be harmful to plants.

    • Hello Pierre;

      Worm Tea requires oxygen to keep the living organisms that make it so great alive. Do not seal the container but leave the lid loose. The Tea will stay good through about 2-4 months if kept cool. It will lose its potency or value as time goes on. It is best to use it as soon as possible.
