My husband has been doing a lot of reading this year on different gardening ideas. He read an article from a university in the States on this compost tea and said he wanted to try it. I don’t have the exact link to it, but will provide a few that I found.
It hasn’t been proven or even tested, that I know of, probably because it doesn’t last. You can’t store it, save it, package it. It has to be used right away.
This is what we used:
Grab a 5 gallon (20 L) pail.
He went to Pet Smart and bought:
10 gallon pump (about $14)
Plastic tubing to fit the pump (about $2)
Aquarium Air Stone (.59 cents)
Container of Fish Emulsion ($9) (Lowes)
Molasses, unsulphured/unsulfured black strap. (you can get this at the Bulk Barn and buy whatever quantity you want.)
Vitamin C tablets (500 mg)
A sock
Compost
Step one:
Fill the pail 3/4 full with water.
Connect tube and stone to pump.
Put the Air Stone in the pail, he tied a small stone from our back lot to the tube to keep it down because it was so light that it floated.
Plug the pump in and let it bubble a few hours. The oxygen it creates gets rid of the chlorine and fluorine in the water. (This is what we read, it hasn’t been tested or proven)
Step 2:
Grab one of those socks that the your dryer ate the other match. Fill it with compost. Tie a string around the top so the compost doesn’t come out and drop it in the pail.
Add 1 ounce of fish emulsion.
Add 1 tablespoon of molasses.
Add 2 crushed 500mg Vitamin C tablets
Let this bubble, uninterrupted for 24 hours.
Step 3
This is concentrated. You can use 4 parts water to one part tea all the way up to 10:1. We even watched a guy on youtube use it full strength.
We are just saying what we did.
We watered all our seedlings with it. It is a soil enhancer and enrichment tea.
We used it on a few things in the flower garden that we have doubles of. That way we can see if it is making a difference. We’ll keep you posted.
If you have any left over, you can’t keep it. Throw it on your compost.
From what he read a five gallon pail can do up to an acre. You can also put it in a spray bottle and spray your plants to resist disease. (Again, not proven)
There are many different methods out there. Just type in compost tea in a search engine or at youtube.
Here are a few links to give you more details.

We are looking forward to seeing how this works. If you have used it before or are planning to, let us know.
UPDATE: I had a great question about why you can’t keep the compost for any length of time. I think it has to do with the oxygen level in it.
Here is a link that I hope explains the science behind it. I know I can’t.
