The Bin

  • I like the design: simple, low-cost, effective.
  • Add a bar of some kind on the top; maybe rip a length of scrap board and place one in each cut notch. This will add stability to the top panels.
  • Don't let this bin get to high. You have no way to remove side panels and turning the pile in the bin will be difficult if it gets too high.


  • If you read a recent post in the past few days, I mentioned the leaf mulcher. I use this one. Breaking them in small bits increases surface area and allows bacteria easier access to the inside of the leaf (some leaves have a waxy outer coating that slows the composting process.)


  • Manure is pretty close to perfect in terms of composting. With a C:N ratio of about 27 it will do pretty well on it's own. the problem with Manure is that it tends to stink because no air can get to the center of a manure pile. Without air, anaerobes take over and make bad smells.

    Composting it All

  • Here's where we get a little nasty: All the manure you have needs to be broken up into smaller pieces; whether you want to do it by hand or with a tool is up to you.

  • It's best to wait until you can make a pile that is close to a cubic yard (3x3x3 ft)

  • use a ratio of 1:1 (by volume) of manure to dry leaves (unshredded.) this tends to be about a ratio of 15:1 (by weight) Most people don't weigh their compost, so backyard DIYers use a volume estimation. If you have 1 cuft of manure, then use 1 cu ft of dry leaves (unshredded.) This will give you a ratio of pretty damn close to 30:1.

  • Layer the manure and leaves, spraying the layers as you go with the hose (not to wet, though!)

  • when your pile is done, the process begins! Your pile temp will spike within 24 hours. Then it will maintain for a few days and steadily decrease. There are a few methods to be employed:

  1. The lazy method: Simply do nothing. It will do everything on it's own but the process will take a long time and the end product will be sloppy and coarse.

  2. The "typical" method: When the temperature drops to 120F, turn the pile -inside out, outside in. Continue this until the temperature no longer gets above 120. Then turn and mix the pile into a final bin to "cure" for about 2 months. For best results, sift the final product through 1/4" screen. Add this material to your soil.

  3. Hot method: Most people don't have enough starting material to make this really feasible. If you have a good strong source for horse manure and a lot of straw, you could do this easily. It takes about 3 weeks to make goo compost with this method. I provided a link below, but the process it layer into pile, let sit for 4 days, then turn every second day for 2 weeks.

    Most people use the typical method in a 3-bin system: bin 1 = active pile, bin 2 = turned pile, bin 3 = curing pile. I employ this method. Once I get my new 3-bin setup completed, I will be posting pictures of compost at different stages. IN the meantime, here is a picture of potting soil components I use: Left to right: dolomitic lime, perlite, compost (the stuff I make), peat moss.

    For added fun, use the compost going into the curing pile as bedding for worm bins. It is rich with food for them (you can add more, of course) and they will pass all of it through them. The end result is a nice, black, humus. I hope to employ a worm bin soon; it's on my list.

I think you're set on supplies. I never used the coir. I just added shredded newspaper and the stuff the worms were shipped in.

Small chunks are fine. I'll give them larger chunks and they handle them. They really don't eat much. Consult on-line, but I think you feed a lb of worms only a half a lb of food a day. I NEVER have them eat that much. I usually have far more scraps than the worms can eat. You can freeze the scraps and when thawed, they're soft and easier for them to consume. Blending is fine, but not necessary. Really, just putting the entire peel and cores is fine.

I feed the worms on one side of the bin for a few days so I can harvest the opposite side. Not all of them will move, so I pick out the worms and put them back into the bin. They aren't all that bothered.

I think those worm contraptions are more efficient at separating worms, but I've never owned one. I have a small rubbermaid tote with holes.

Starting the bin is kind of tricky because it needs to have the right moisture level. I wouldn't buy a meter. Instead, I'd save it and spend money on a worm house later. Visually inspecting the bin is really all you need to monitor moisture. Also note that some veggie/fruit scraps can quickly add moisture to the bin. They love watermelon rind, but it will add a lot of moisture so use sparingly unless the bin is too dry.

They may try to climb out when the bin isn't the right moisture level, temperature or when the bin is new. Don't fret.

For kitchen waste, a vermicomposter is ideal. I built an OSCR jr from these plans I found online and it lasted for about a decade and a half before the plastic became brittle from exposure to sun/elements. I'm in the process of building a new one (pay attention when drilling the holes, one of the three bins is done differently). The worm castings and the tea that drains into the bottom bin are excellent fertilizers and maintaining the bin is a cinch.

Having a pair of bricks to place in the bottom/drainage bin is helpful to keep the worm bin from sitting in liquid.

I'm going to either install a stop-cock or at least drill a hole and keep a rubber plug in it to make draining the bottom bin easier.


For yard/garden or any other bulk/high volume a larger compost bin will be necessary. I find the commercially available ones to be too small. I built the three bin system detailed in the book "Let it Rot!" which is also an excellent resource if you want to understand these processes a little better. The three bin system works fairly well at handling grass and hedge clippings, leaves, old pine shavings from inside the chicken coop, etc.


I almost exclusively use the worm casting tea for watering my houseplants and plants in containers, likewise the worm castings get spread primarily as a top dressing for the same containers and the surplus then goes to the garden and landscape plants.
The compost from the big triple bin gets used throughout the yard as mulch or to till in with new plants.

Yeah I would also say to stop adding. A month is a good amount of time. Keep the pile going on standard operating procedure. If you really want to turn it every three days that may help. It also looks a bit wet to me so ease up on watering maybe.

I’ll probably get flamed for this but I’ve gotten great results from this Job’s inoculant in the past. A bag costs $5. You might consider adding some before you process for another month.

But adding more unprocessed material to a pile that looks unfinished may be counterproductive, unless you have strong reason to believe your materials are grossly unbalanced.

FCMP Outdoor IM4000 Tumbling Composter, 37 gallon, Black

We got this one and it’s been great so far. I’m sure there are fancier ones but this one works just fine. It has 2 chambers and is pretty easy to empty. Only downside was that it has like 500 screws to put it together the first time!

The compost bin I purchased came with a Wing Digger. I didn't expect it to work well, but I have been pleasantly surprised. It works well enough for turning my pile, which consists almost entirely of coffee grounds and shredded paper and leaves. Using this, I never have to use a pitchfork or dump out the compost and pile it back in.

If I were to get a new one, I would consider getting one with two pairs of wings and an extra hand hold. It looks a little sturdier, and should turn the compost at least twice as much.

I bought this one:

Handles paper great, not cardboard, but I have enough paper now that I can use this no problem. Lots of newspaper thanks to my neighbor. :)

u/frenchpressgirl · 2 pointsr/composting

I keep my kitchen compost bucket on the counter, by the sink. I think accessibility would help you. When cooking, you can set up your cutting board (or whatever) near the bin so you can easily transfer scraps.

Oxo makes an easy-open/non-latching countertop bin — that might help it “feel” easier too.

I think adding a multi-bin setup would make your life more complicated.

I'm in Utah. My pile is at 130 degrees! I have this same compost thermometer, which is Cate's Garden (no guarantee that Amazon is the best price, just linking).

u/sugarhigh22 · 1 pointr/composting

Late to the party but wondering the same thing, was hoping something like this might work but I have my doubts

u/caltomin · 1 pointr/composting

I have a slightly different YIMBY that is a little smaller capacity and is a dual-chamber. It's been working fine so far, although it is a little too small to really get cooking without some direct sunlight to heat it up. Also note that it drains pretty freely since it is made out of 8 panels rather than being a solid container. I've never had to add water, but you'll want to put it over some ground that you don't mind getting drained on.

u/dross99 · 3 pointsr/composting

I got one like this a few years ago. Doesn't smell at all. Just don't put any animal bones/meat/oils and you should be fine. Has never smelled bad or had any unusual odors ever.

Tumbler is fine too. I prefer the one that sits on the ground though because worms find their way in it when it's not too hot.

Mother Earth News has a reader question that mentioned 3 years for dog mushers in Alaska to compost it completely, due to the cold climate, but an Ag extension test got it down to 4-8 weeks. They couldn't say for certain whether it would kill roundworm because they couldn't find any infected stool to work with, but theoretically if the pile gets to 140F it will be clean. The six months I read in this book Holy Shit, I believe, but it has been awhile!

u/rahabzdaughter · 1 pointr/composting

I've never dealt with such a problem. But my gut tells me to throw a bunch of carbon and nitrogen at it to make it really hot and that should kill anything bad in there with a high nitrogen for a while. You'll also want to add sod as it's a starter. But I think hit it hard with the grass trimmings for the nitrogen to run it hot.
Almost everything I've learned about composting came from this book, that I LOVE.

u/iveo83 · 1 pointr/composting

it was between 160-180 for sure b/c it was off the chart and I was afraid that might be bad / start a fire.

I got this one

I made my bins to big so they are such a bitch to turn. I guess I just gotta suck it up and pull everything out and turn it around. I figured sitting the entire fall/winter would have been good enough

u/Sovrage · 2 pointsr/composting

I've read your replies to comments and recommend this. I'm in a tiny apartment too! just drill holes on the sides/top.

I also have a lot of nitro waste and obvs no easy access to carbon since I don't clip my own lawn but I've been using paper bags from groceries, toilet paper/paper towel rolls, and going around my neighborhood with my daughter and picking up dead leaves/twigs to dump in for carbon
