For the weight I would suggest mixing a blob of concrete and sticking a piece of scrap metal into it to act as a handle so it can easily be pulled out.

I use a couple of wheelie bins and just scrunched up chicken wire to make a mat in the bottom. I tilt the drum slightly to the front and all the liquid comes out from a single hole at the front, straight into 1 gallon plastic bottles. I cover my bins and the juice comes out quite thick. Worked just great for me for 20 or so years. I have a 40 foot x 40 foot comfrey patch right next to the bins.... and the compost bins

[@Mrbfgray]

@@craigdonald551 Appreciate the suggestion, my comfrey is doing better this yr, dropping a lot of leaves but not entirely wilting like it used to. About yr 3 I think now, getting better established, only sporadically watered it even at 110F. (water is expensive here)

[@Mrbfgray]

@@craigdonald551 For what it's worth--comfrey is reputed to have litany of 'medicinal' uses. I'm more or less immune to bee stings (last I checked) but got nailed by a wasp several months ago and it hurt a little for days, not used to that. Then I got wasp stung again a week ago and it dawned on me comfrey might help, half hr later picked a fresh green leaf, with no expectations, wadded it up to juice it into stung thumb. Easily could be coincidental but sting went away quickly.

I don't have any nettles or comfrey but I do have weeds and grass clippings that would work. Thanks for sharing this info. I really did not like the stinky stuff.

[@LearnPermaculture]

Pretty much any leafy healthy looking plant that you know not to be toxic should be good. Grass cuttings however tend to clump together and go anaerobic (even without a weight on top) so you might be able to put a little in your mix but not too much. Nettles and comfrey have quite chunky stems which create air spaces in the mix - grass does not.

[@jonisolis9645]

Thanks for the added info and you did not say what this liquid smells like. Smells like dirt? @@LearnPermaculture

[@yellowbird5411]

Your method is so much better due to the often off-putting smell of fermenting plants in a water solution. I've done that, and the smell won't even get off my hands. It is distinctly unpleasant, in my opinion. Your method seems to work as fast as the water method, not even needing covering to discourage mosquitos or smells escaping. Those two things alone make your method better. I am going to try it, but probably not with a barrel, maybe just a five gallon bucket to start and see how it goes. I have the buckets, the weights, the out-of-control vines and weeds, etc. and in this season in Florida, the rainfall. There is a man who converted his 1,000 acres over to natural fertilizer using the water method plus micro-organisms for breakdown. But it takes a year for the breakdown to be complete. He has big tanks that strain the solution and sprays his fields. I don't know if your method would help him or not, as he does focus a lot on fungus/inoculant. Anyway, his KZbin channel is The Plant People, and I think you both have much in common. Perhaps you could share information. The method of making "home brew" is key to circumventing the fertilizer shortage/price, even for big growers, if they are willing to learn this method of soil building. Thank you for a great video. I have never see this method before, in all the videos I have seen. Please make more of them to keep them circulating on KZbin and other sites so farmers looking for alternatives can utilize your method. You could do a series of "shorts" on KZbin, and that would help.

[@LearnPermaculture]

Thanks Lynn, I shall look up The Plant People! I learnt how to do this from my friend Pat Bowcock at Ourganics and I think she learnt it in turn from someone in Eire. Anyway, the limiting factor I think is the amount of leaves you can obtain as raw material, but even making a little can make a significant difference.

[@SimpleNaturalPractical]

Great stuff mate, love your process to liquefy weeds to fertiliser without a stinky brew, airating with aquarium bubbles is fun too, but this is the simplest for sure, I'll definitely be doing this. Thankyou

[@LearnPermaculture]

Thanks Emily! I'd say any plant that produces lots of fleshy leaves and is non-toxic could be added to such a mix. If they're growing well enough, they probably all the nutrients that plants need to grow in your soil. It's good to experiment!

[@LearnPermaculture]

Thanks! Yes, it works fine - no smell from the barrel. The only thing that will create a smell is if you bottle it for later use without filtering out any bits. In a bottle those bits will decompose anaerobically and make a bad smell.

[@Adnancorner]

You can use large pebbles or large particle concrete sand from the riverside or from the fields where you can collect while planting plants in the soil. 1 inch pebbles can works as well, and it would be a one time investment as they would last a long time. There is also a possibility of you trying glass beads too, which will never decompose as the pebbles will shrink over the years because of the acidic liquid from the rotting of leaves.

[@dogslobbergardens6606]

Makes sense to me! It reminds me of the KNF prep Fermented Plant Juice, but they add a lot of raw brown sugar with the plant material to draw out the liquids much faster and feed beneficial microbes. That certainly works, but at least in my area those amounts of raw sugar end up being pretty costly, and that partly defeats the purpose of making one's own fertilizer in the first place. I have more time than cash, and there are other good ways to encourage the friendly microbes. I've been using anaerobic comfrey and weed teas for a couple years now, and I'm sort of used to the, uhh, "tastiness" of them. But my wife would probably appreciate me using this version instead ;)

[@LearnPermaculture]

I think she might. :)

[@zam1007]

sugar? any free fruits or berries e.g. blackberry, spoiled strawberry, apples can perhaps be a sugar source.

[@LearnPermaculture]

@@zam1007 Sugar is usually added to make compost teas or other ferments. That's a different brew from this one. Fermenting nettles with sugar will make a much stronger fertiliser. At the moment we eat all the fruit we get, but some day we might have surplus. :D

Thank you. Its so much better without the smell. How long does the liquid keep?

[@LearnPermaculture]

It is isn't it? I store the last batch of the autumn overwinter and use it in early spring, so it can keep quite a long time. The most important thing to do is to sieve it well before bottling it - if there are any bits in it they'll decompose anaerobially in the bottle and make it smelly. Then keep it somewhere cool and dark - we put ours in the garage.

[@lpmoron6258]

Looking at it, it would be a really good way to pre-process any sort of perennial weeds before adding them to the compost heap. Once they've been in there for a few months they won't regrow, even from roots. You wouldn't be so sure about the content of the liquid but that's a small price to pay. Thanks!

I might have missed this, but do you dilute the slurry before you put on your veg? And, in a real dry climate, will the debris break down without water? I live in the high desert of SW Colorado. Thanks. Great presentation.

[@LearnPermaculture]

It's very much a liquid, but it does need diluting. I'll add one part to between ten and twenty of water (half a litre in a ten litre watering can) depending on whether it's already been diluted with rain.The leaves do have some moisture in to begin with, but a little sprinkling of water from time to time will ensure the decomposing microbes have enough moisture to do their work.

[@tomfisher3117]

I've used comfrey tea for years. I also chop and drop it as mulch. I use Russian Bocking 14 with an NPK of 1.8-0.5-7.0. I brew it in a 32 gallon black garbage can. Let it sit for 3 months to a year. I don't strain it, I just take the sprinkler off the can so I don't clog up the cans. I also use fermented plant juice made from comfrey which I foliar spray. I use only 1/4 teaspoon for 5 gallons. It's very powerful stuff. I also make lacto microorganisms which is also fermented. I combine it with the fermented plant juice and spray it every two weeks. It works pretty well. The only other addition I use for supplemental fertilization is some fast acting bone meal . I will use it when I start to see flowers forming on my tomatoes and peppers. Love it! Blessings to you. This was a wonderful video.

[@LearnPermaculture]

Thank you Tom! Yes, the Bocking varieties produce a lot of leaf and stem in a small space compared to the smaller ones, though I find the latter good for chopping and dropping around young trees where they won't overwhelm them. It sounds like you have a great system there. :)

[@helentc]

I like this method best. The water method, obvious drawbacks, especially when on a shared property. The fermentation method requires the expense of the sugar. I don't see any drawbacks to this one. I also appreciated hearing which plants preferred which, well plants, ex; Comfrey or Nettles. Not having a current source of nettles, Comfrey will be my go to for now, with the addition of my weeded plants. Thank you for a great video. Appreciate the "scrounged parts" aspect too. :-)

I stuff slightly chopped leaves in the top, get the juice at the bottom. I've never actually removed any leaf matter from it, it all just seems to disappear. The whole kit is just inside the greenhouse door, so it's a bit warmer. And close to where I want to use it!

First year grower here, trying to get away from spending so much money and stay natural. Been watching a number of videos on JLF etc and blessed to have came upon this. Would you say there's a benefit to nettles vs. comfrey or is it pretty much the same fuel for the process? Thanks so much for posting your experience.

[@LearnPermaculture]

Hi Xander, glad you're finding it useful. Nettles and comfrey are complementary. Nettles come earlier in the year and are high in nitrogen, which your young plants need to make stems and leaves. Comfrey is a bit later and is rich in potassium and also phosphorus which your plants need to make flowers and fruits. A prefect combination, but if you only have access to one to begin with, that's still good. Happy gardening!

Excellent demo! Thanks for sharing. Will also try this with decomp as items from the garden are done and the fall leaves start coming down. Would like to know the growth production increase with using this method.

[@LearnPermaculture]

Thanks! The best time of year to make this is when the plants are actively making leaves - generally in the spring - as we're collecting the sap/juice. Once plants start making flowers and seeds they pretty much stop making leaves. The liquid does store very well though - in a cool place - and if you ensure that you don't bottle any undecomposed 'bits' it won't smell bad either. I haven't specifically compared the results of feeding with nettles or comfrey vs any other fertiliser, but it's certainly an improvement on none and apart from your time it costs nothing.

use charcoal to suck up the smell and make at the same time biochar

[@LearnPermaculture]

That might work to a degree but an aerated compost tea would be my choice for inoculating charcoal to make biochar - then there's no bad smell to deal with in the first place.

[@funkarola]

I guess unless you're filling it right up you can cut part of the barrel off so it's not so tall too

[@LearnPermaculture]

Yes, indeed.

[@funkarola]

@@LearnPermaculture thanks 🙏 great tutorial I'll definitely be doing this! I'm looking for ideas for compositing chicken manure too

[@LearnPermaculture]

@@funkarola Well, chicken manure is high in nitrogen so I'd mix it with anything that's high in carbon.

[@donnastormer9652]

I like this idea. You might want to put marks for where the line of holes in on the outside of the bucket. I’m old and would forget where they are over time

[@LearnPermaculture]

Thanks Donna, that's a good idea. On mine I've drilled them in line with the seam on the barrel so I can use that as a marker.

[@smithy4121]

Thank you I really like this idea. If your not careful feeding your plants organically can cost a fortune I really like this way of making my own, none stinky fertiliser in large ish amounts.

[@LearnPermaculture]

It can indeed. Doing this is really a no-brainer!

[@susanravizzotti2287]

Thank you for the thorough explanation. I’m in the subtropics in Australia, lots of sunshine and moisture so I think this method is perfect for the many weeds I get. I don’t like throwing any organic matter away unless it’s diseased so I’ll keep the pernicious weeds for the anaerobic water method and other weeds for this aerobic method. Great advice, thank you 🙏

[@LearnPermaculture]

Thank you Susan! :)

[@leodeboca]

excellent!

Is it an idea to soak seeds in the nettle liquid with water and what ratio should I use. And use it also for the soil for those seeds

[@LearnPermaculture]

I've never tried that - seeds tend to have all they need for the first few weeks of growth, but you could experiment (with something you have a lot of, such as lettuce) and see if it makes a positive difference. If I did I think I'd use it more dilute than when feeding a large, hungry plant. Perhaps diluting 40 to 1 instead of my usual 20 to 1.

[@trish3580]

Thank you so much for this video-perfect for me in so many ways. Your teaching style is so welcome. I have a very modest and am not very strong but this looks very doable for me....I don't have orange bricks but will figure something out (none to find nearby). Re comfrey - I don't have nettles but have an abundance of comfrey a couple times in the summer (right now it needs cutting). Can I use comfrey for everything in my garden? I heard you mention tomatoes but I need to have something to use on everything-potatoes, greens etc..maybe berries? Thank you so much for your help with this. .

[@LearnPermaculture]

Yes, anything that will lift the barrel above a container will do - my friend Pat uses a pair of old van roof bars. Comfrey is very good too. It's more suited to feeding plants when they are in the flowering and fruiting stage and comes a bit later in the season, but I always make a barrel of comfrey liquid too. Yes, this will work for any plants that need a feed though for potatoes you could use the leaves as a mulch instead and save the work. I actually wrap a comfrey leaf around each seed potato when I plant them in the spring.

[@novampires223]

Terry King, a wonderful master gardener does this on a grand scale on his plot in Britain. Can't remember his channel name, but it should show up with a KZbin search of his name.

[@LearnPermaculture]

Thanks! Yes, I see that he uses the pipe method, but on a bigger scale than the usual drainpipe. Good if you have a structure to attach it to. Not sure he has any more volume than a butt like this can generate though...

[@elizabethasoy6249]

Thanks for sharing,very helpfulnto a new beginners to have a garden at our backyard

[@LearnPermaculture]

You're welcome Elizabeth. :)

[@flash_flood_area]

Your region is extremely different from mine - we have very little excess greenery, but I appreciate the clear instructions and demonstration. Now if I can only find enough weeds to fill a bin

[@LearnPermaculture]

Yes, techniques need to be well-suited to their environment. This works very well here in Britain and other cool temperate places where these plants grow abundantly.

[@flash_flood_area]

@@LearnPermaculture Sometimes we get an abundance of wild mustard, cheese weed, or amaranth, if the rains are good. So far this year, it has been very sparse

[@yellowbird5411]

If you are in a desert area, perhaps cactus would be a good source. Green tumbleweeds, certain thin tree leaves, etc.

[@flash_flood_area]

@@yellowbird5411 Thanks. When we get a big monsoon season, like we just did, there's a lot of weedy biomass. I've planted a few things, including a mesquite tree, palo verde trees, an ash tree, and cactus, etc

[@The_Real_Casey_Timmins]

Thank you. Doing that next week with my nettles and comfrey. Potatoes just broke ground

[@LearnPermaculture]

The new growing season is always exciting!

[@GeoffSayre]

I just built a slightly smaller version of this based on your video. I had all the materials needed laying around the property. Filled it up with what weeds, grasses, and wild flowers I could cut off the edges of the lawn and garden. I have a question though: do you add water when the weather is very dry? Thanks for sharing this technique. I'm very excited to start harvesting "free" fertilizer!

[@LearnPermaculture]

Hi Geoff, yes, the bacteria will need some moisture. Water it if it looks a bit dry, otherwise it should look after itself. Happy experimenting!

[@GeoffSayre]

@@LearnPermaculture thank you for the reply and advice!

[@GeoffSayre]

@@LearnPermaculture so as an update: I used the extracted fertilizer for the last few months. Using weeds and wild flowers as the raw material produced plenty of liquid. It did not seem to be a strong fertilizer. I had to apply it weekly to get results. But it definitely worked! The plants I tested it on grew well and had dark green healthy leaves. I'm building a second larger extractor for next season. This design is very useful!

[@LearnPermaculture]

@@GeoffSayre That's great to hear Geoff. Nice work! :)

[@yellowbird5411]

@@GeoffSayre Perhaps using a bit less water in the dilution would help?

[@kicknadeadcat]

I have found if I put an aerator in after the comfrey is finished for a couple hours it removers most of the stink.

[@LearnPermaculture]

Thanks, is this for the traditional version with leaves in a tank of water, or after this version? What size pump do you use and do you also use an airstone?

[@cowboyblacksmith]

I may try a smaller version using my bokashi 5 gallon bucket, it has a drain hole and everything and a false bottom with holes.

[@LearnPermaculture]

Worth a go Paul, it's a system that can be scaled up or down - until the container gets too small for the leaves of course. :D

[@tomlawless4406]

What if it’s raining a lot would you cover the top I feel like I would make a kind of umbrella lol

[@LearnPermaculture]

Yes I do. The bacteria that break down the leaves need a little moisture but not too much. so if you're expecting a lot of rain then covering the bin would be a good idea. Otherwise you'll be having to empty the containers more often and your liquid will be more dilute. I have a couple of old short scaffold boards I use for this job.
