If you’re wondering about a few simple steps on how to make worm tea, then you’ve gotten a hold of the right reading material. Worm compost tea is just the liquid version of worm castings; and it is a nutrient-packed supplement that can very well improve the quality of your lovely plot. You can read more from this article to know how to create tea made from worms castings.

Finding the right supplies for making easy worm tea

You can choose to use red wigglers or nightcrawlers castings for this specific tea. Either way, the same nutrients that are contained in these two compost types are also as valuable as the other. Now as soon as you’re settled on using your preferred worm compost, prepare all the other necessary materials for making your worm compost tea. You’ll need to prepare the following:

  • A bucket - Use a container that can hold about 5-gallons of water
  • Water – Use only water that doesn’t have chlorine in it. If you only have tap water available, make sure that you leave it to settle first (for as long as 24 hours) before using it.
  • Corn Syrup or Molasses – This is what you’ll feed the microorganisms in the worm tea
  • A Bubbler – Use this to help bubble and aerate your worm compost mix
  • An old sock – Only use an old sock that doesn’t have a hole on it
  • 2 scoops of worm compost – You won’t be able to create your earthworm castings tea without these goodies

Creating your own worm tea blend

Just like how we make our tea, we prepare our usual tea bag, and soak this in a cup of hot water. Tea that’s made from compost worms castings actually goes through the same process (only that humans nor animals don’t drink this type of tea). Now, what you must first do is to fill your hole-less sock with your scoops of castings. Have the sock tied using a string or band, and then have it soaked in the bucket of water. You can choose to leave it floating or have it tied to a string, so that it stays put in only one area. The juice draining below composting worms' composting bins are concentrated worm tea.

Why corn syrup, molasses and chlorine-free water is important

Why is corn syrup or molasses important in your worm compost tea? Well, the microbes that are made present in your tea will use this as their source of food. Feed them ample amounts of these sugary treats and they will be able to work for you for as long as possible. These microorganisms are also the ones responsible for making your compost tea fresh and teaming with life (the process helps make the tea to stay in aerobic conditions). Chlorine-free water on the hand should only be used in this kind of mix. Deciding to use water in this condition will only kill the microbes.

Leaving the mix to settle before applying it on your garden soil and plants

The last step to this how to make worm tea set-up is to have the tea mix aerated using a bubbler. Leave this to bubble for about 24 to 36 hours before using the blend on your garden. Now, as soon as the process is done, immediately use your worm compost tea, before it turns anaerobic (best used within 1– 2 days from brewing).

      It's scary to think about how much money we have in those planters, but then it's a peennarmt part of the house so it's not too hard to justify the expense. We live not too far from an area that has a lot of commercial greenhouses, so there are warehouse-type businesses that are used to selling by the truckload. We made several trips with the trailer in order to fill them up for a lot less money than if we had gone to a local garden store or Home Depot.Much of the mixture is a 50/50 mix of peat moss and vermiculite. Added in is some compost and some Fafard 3B potting soil. The 3-B is an inexpensive commercial potting soil mix that has a lot of ground pine bark in it. The bottom part is plain 3-B potting soil since it is the least expensive part and it is below the root zone for the most part.Yes, that is actually a waterproof sealer that we added to keep water from seeping in through the cracks between the blocks. The folks who laid the block did it as if it were a house, so the outside was nicely finished, but the inside was a bit rough. My main concern was the moisture seeping out and causing a lot of mildew and algae growing on the outside and looking ugly. Although the utility aspect is the main focus, the aesthetic part of gardening is important to me also.One thing I learned when putting the sealer on is that after you mix the water in, it takes several minutes for it to thicken up enough to use. I ended up wasting a lot of it trying to get the right consistency.If I were to build another one, I would probably only go 2 rows high rather than the 3 that we used with these two. It sure is nice and comfortable to work with, but I'm not sure it was worth the extra expense now that it's finished.

      You could use radishes, leaf letucte, beans, almost any veggie. Other than melons, I can't think of any fruit you could use. Keep your soil moist, but not soggy. Make certain that your growing container has a drainage hole. You'll need sunshine for the seeds to sprout and grow into sturdy plants.
