    I love the video. I’ve heard it said that the advantage (especially with aerated tea) is the micro-organisms more than the nutrients. I *seem* to have an improvement when I used to apply that to a lawn… at least as effective as the expensive products you can buy to stimulate breakdown of thatch, especially considering I used chemical fertilizer. (Though it did require regular application, which is a lot of mulch water.) Like you, I found it better to simply place some steer-plus (composted steer manure and wood chips) atop certain beds. I figure watering over a season or two releases the nutreients over time without the stink. The best "weed tea" I found was decades ago, where a friend trapped the water runoff from his rabbit dung in a pit.

    A week on till it’s grey on top..



  3. Narin the Bearded Alien on August 15, 2022 at 10:02 am

    i’ve never heard anyone say weed tea has nutrients. the claim was always microbacteria and fungus particulates for all the videos on it ive watched. i’ve never heard a claim that they have nutrition.



  4. zazugee on August 15, 2022 at 10:02 am

    i did use it, even tho i was never really convinced by comfrey tea not used any aerated compost before
    and the reason being is i have bermuda grass everywhere, and composting or turning it over the soil was out of the question bc i will just get the seeds back into the soil
    aerobic decomposition should kill the seeds after a few months and i keep reusing same bottles to water pots to inoculate them with new flora, not much interested in dissolved nutrients bc they wash away fast
    bacteria tie up nutrients and are enemies of plants? no problem, bacteria turn over fast, and it’s convenient bc they keep nutrients in place till they die close to the plant roots



  5. Judy McKerrow on August 15, 2022 at 10:02 am

    So basically if I buy some comfrey to make weed tea with I’m wasting my time and money?πŸŒΈπŸ’šπŸ™ƒ Help information as always, thank you πŸŒΈπŸ’šπŸ™ƒ



  6. Matthew King on August 15, 2022 at 10:03 am

    I run my comfrey through a meet grinder or use ground alfalfa and kelp meal. I use lactic acid and molasses to ferment in a container with and air lock. It has a sweet sour smell and the low ph keeps it stable.



  7. davhutton on August 15, 2022 at 10:04 am

    Another great video Robert.
    Im sure it will be useful for the gardening community…..



  8. Andrzej L on August 15, 2022 at 10:05 am

    Good job debunking the myth. I’m very new to gardening but I am glad to have found your channel. Kindest regards. Have a great day!



  9. BJ Brown on August 15, 2022 at 10:06 am

    I have wondered about this. I made some weed tea a few years ago and my mother asked me why my garden smelled so bad. I told her it was weed tea and she politely asked me to not do that. She lives next door and it wafted over to her garden!



  10. John Dove on August 15, 2022 at 10:06 am

    This is awesome, now I can throw that stinky bucket in the bushes, lol. I have been using fish tank water as it is supposed to be high in nutrients as well….. now you got me thinking. Great work sir!



  11. victormcox on August 15, 2022 at 10:07 am

    I’ve been searching high and low for a video like this. Thank you so much. I knew there had to be a science behind this fertilizer tea method. I have tried it. I really haven’t noticed any difference. I didn’t know that it should help if the tea decomposed a lot longer. I guess I was looking at this from a self-sustaining angle. However, while I’ve got the money I’m going back to miracle grow! 🀣🀣🀣 Thank you so much for taking the time!



  12. Bakthawar Behrooz Bhagesh on August 15, 2022 at 10:07 am

    I think, must have to use the right bacteria to decompose it.



  13. Metta Analysis on August 15, 2022 at 10:08 am

    Love it. Tired of people trying to get "likes" by peddling bs that hasn’t been tested



  14. Empty Nest Gardens on August 15, 2022 at 10:13 am

    I wonder now about worm casting tea. I’ve always thought why not sprinkle the worm castings instead of brewing a tea?



  15. Ansa Bulfone on August 15, 2022 at 10:15 am

    I appreciate your science approach, but was two weeks enough? I also question the materials put into the sample. I think a larger variety of plant material and longer time would change the result, as would aeration.



  16. skashax777x on August 15, 2022 at 10:18 am

    this is a well-done vid that follows the scientific method well and could be considered a good experiment,
    your conclusion is well thought out and hits most of the questions that I thought of when you were showing the solid test results of the water,
    I would suggest for further study, what are the macronutrients and how does the anaerobic bacteria affect the nutrition of the plants and or soil life.?
    as I’m sure there is more to the tea than just NPK,
    also, how would an aerobic tea compare the anaerobic tea?
    As the aerobic tea should have a better smell rather than the fermented decay that the anaerobic tea has.



  17. Lettuce Salad on August 15, 2022 at 10:19 am

    I don’t have time to make weed tea, I’m too busy burying fish. LOL



  18. Garden Fundamentals on August 15, 2022 at 10:20 am

    We had a couple of comments saying that JADAM uses weed tea and has tested it and found a good NPK – but as usual they neither provided the data, nor did they provide a reference to the testing. So I went and found a JADAM manual and it actually tells followers not to test their home made fertilizer. I also checked out several pages and videos about JADAM – none provided the NPK values.

    It is easy to claim a high NPK when you have no data!



  19. Eric Lion on August 15, 2022 at 10:21 am

    Thank you very much for scientifically illuminating these unspeakable myths and explaining why they are not true. I’ve been looking for a garden channel like this for a long time and finally found it. I would be happy to recommend you. Please make many more videos like this.



  20. Marc Derelle on August 15, 2022 at 10:24 am

    Well done. Plants are food but without microorganisms to chew them, can’t be released to plant available form nutrients. That’s where decomposition /composting is needed. (Has to be aerobic to avoid it to turn pathogenic!)



  21. CitiesTimeLines on August 15, 2022 at 10:25 am

    So what about using different plants in a mix for insect or other pest repellants? Like tobacco juice or hot peppers?



  22. Empty Nest Gardens on August 15, 2022 at 10:26 am

    Once again proving why you are my go to for quality gardening info πŸ‘πŸ» Yup I’m sticking with chop & drop and my compost bins.



  23. Don Gemus on August 15, 2022 at 10:27 am

    Thanks again



  24. Clive Champion on August 15, 2022 at 10:27 am

    Compost tea perhaps? I have done this with apparent success.



  25. James Kempen on August 15, 2022 at 10:28 am

    Drink it! What ever doesn’t kill you will make you stronger.



  26. blazingearheadsgarage ozarks on August 15, 2022 at 10:28 am

    Obviously you’ve never looked into a jadom book…
    Anaerobic putrification isn’t a tea it’s
    A ferment… Quoting the author a 55 gallon barrel or 5 gallon that is continuously added to and a melting pot of nutritional value.



  27. Rocking Roli on August 15, 2022 at 10:29 am

    Been there done that, just does not work



  28. Gal Beeri on August 15, 2022 at 10:29 am

    I searched for information about bokashi and found your website. I love your additute and info. Thanks 🀠✌️



  29. Shawn G on August 15, 2022 at 10:30 am

    The thing I find interesting is how often people that advocate for this stuff like to talk about how things are done in nature. Well plants didn’t evolve to have rotting vegetable juice sprayed on them. Nothing "natural" about that.



  30. Sue Bar on August 15, 2022 at 10:32 am

    Thanks for the info…I’m going to test my stinky brew. 😊 I collect seaweed every spring, rinse it, blend it and stick it in a bucket with a lid. I stir it periodically and let it sit for a couple months. It’s easy and the plants seem to be benefitting.



  31. Captain DeStructo on August 15, 2022 at 10:35 am

    The proof is in the pudding and since I’ve been adding fermented tea to my 28, 25 gallon container vegetable garden, it has never done as well as it is now. I’m not saying it was doing amazing before, but it has certainly made a noticeable improvement.



  32. Sister Goldenhair on August 15, 2022 at 10:40 am

    Great video. Thx for info.



  33. WildEdibles on August 15, 2022 at 10:42 am

    I use comfrey most arnd always add molasses i didn’t buy it yet this year and my brew is not very bubbly
    Ive never tested mine because i didn’t buy or know i could buy a test
    Some nutes are water soluble but not all
    It be interesting to find out
    I use flowering plants like dandelion greens and flowers, comfrey,docks, ….i look around the garden and find say yarrow… sunchokes
    Ive tried adding strawberries and watermelon rinds and rotting berries it does make it smell better
    Diluting well depending on what needs it and how much i have
    1:4 or 1:2
    Depending on if something needs a good boost say a broken damaged plant
    Or if i want good flowering and fruits
    I use my weed tea for my weed too lol works great for me
    Oh ya banana peels too….
    Its done in two weeks or shorter because the bubbles stop
    When making compost tea you want the bubbles because of the microbes
    I also heard mixing sugar water and adding it to your garden gets the microbes going and your garden will grow too so???
    Maybe the two week brew would be better because they still have microbes at thier higest
    I reuse the same plant matter because it does lower in mass so i add more plants and mollassas and start over
    Ive done this for …oh over five years easy now impoving every year i think anyway except forgetting the mollassas this year lol…. maybe thats a good thing i will have a look at it



  34. Gilbert Arzner on August 15, 2022 at 10:42 am

    What about aerobic bacteria with a air pump, would this be different? I have a lot of Mares tail and Mullein, which might bring a lot of minerals from deep down in the soil. They wouldn’t register much on NPK tests, but might have a lot of the other nutrients.



  35. Pierre Shasta on August 15, 2022 at 10:44 am

    Always so interesting, once again, the proof that there are far too many people who give false information.πŸ‘πŸ‘



  36. Joe Britten on August 15, 2022 at 10:45 am

    I use grass clippings and banana tree leaves mixed in a tea now and then but I always use worm castings black strap molasses and kelp other times I use other meals in there and I have good luck



  37. Myles Falconer on August 15, 2022 at 10:45 am

    You might want to read nigel palmer book, the regenerative growers guide to garden amendments. Lots of analysis of different weed teas and other homemade fertilizers. I think the ultimate experiment would be to grow plants with these diy fertilizers and run controls for comparison…



  38. MeowMeow on August 15, 2022 at 10:48 am

    πŸ˜‚πŸ˜‚πŸ˜‚ I’m glad I didn’t watch those videos



  39. There's some lovely filth down here on August 15, 2022 at 10:49 am

    A few guys on the allotments make nettle tea. But they have it in a water butt for two or three months at least before they use it. Also, because they have nettles growing right beside them anyway. When it’s done, nothing is left but the fibres. So I’d say they are getting something out of it. But they only use it to supplement their regular fertilizer use, or on things like cabbages or other brassicas.

    I think they would be much better off just going in the watering can. Filling that up with water, and then using it on their plants.



  40. Ronald Hiser on August 15, 2022 at 10:50 am

    This is why I love your content.



  41. Leo Aldebaran on August 15, 2022 at 10:50 am

    I have comfrey plants growing around my greenhouse and I have to cut them down three times a year because they grow too big and block out some of the light. I’ve been using them to make comfrey tea/fertiliser. I currently have about seven old plastic milk cartons of the previous batch and two bucketfuls that I made eight weeks ago still brewing away. I keep forgetting to use it, but after watching this there’s not much point in using it anyway. In future I’ll just chop it up and add it to the compost heap. And yes, it stinks to high heaven. The neighbours were downwind of it one evening and I heard them complaining about the smell.



  42. RIP INDUSTRIES on August 15, 2022 at 10:52 am

    Why not use swamp water



  43. Andyourlittledog on August 15, 2022 at 10:54 am

    This was really helpful. I’m making seaweed tea…guess I’d be better off composting it



  44. Dan Sobien on August 15, 2022 at 10:55 am

    Your analysis and conclusions are incorrect. The nitrogen in the tea is tied up in the bacteria that is breaking down the weeds. This nitrogen is in the form of protein with will not show up on the type of test you used. The bacteria are anaerobic and die shortly after being exposed to oxygen releasing some of its nitrogen for plants and providing food for other microbes that eventually become nitrogen for the plant. That is why so many people swear by it.



  45. Benchmark Computing on August 15, 2022 at 10:55 am

    Thanks for the great vid…Do you know if leaving bananas in water for a week is pointless too, as there are so many vids saying they make a great liquid potassium fertilizer for potatoes, ginger etc?
