How long does it take to make compost in a bin


How do I make my compost?

You can make compost simply by adding compostable items to a compost heap when you feel like it. It will all compost eventually but may take a long time and if the mix is unbalanced, may not produce a very pleasant end product. With a little extra attention you could improve things dramatically. If you want to produce more compost in a short time, and are able to put more effort into it, follow the 'HOT HEAP' route.

An ideal mix

To make good compost you need a more or less equal amount of 'greens' and 'browns' by volume. You can also include small amounts of the 'other ingredients' listed in the What can I compost? section.

The COOL heap route
  1. Try, if possible, to collect enough compost materials to make a layer of at least 30cm or more in the compost bin. Weed the garden, mow the lawn, empty the kitchen bucket! Mix in some straw, woody prunings, scrunched up cardboard packaging eg cereal boxes – this helps create air spaces within the heap. It may help if you place a few woody plant stems or small twigs on the bottom first as this will improve the air circulation and drainage
  2. Continue to fill the container as and when you have ingredients. If most of what you compost is kitchen waste, mix it with egg boxes, toilet roll middles and similar household paper and cardboard products to create a better balance
  3. When the container is full - which it may never be as the contents will sink as it composts - or when you decide to, stop adding any more. Then either just leave it to finish composting (which could take up to a year) or go to Step 4
  4. Remove the container from the material, or the material from the container – whichever you find easiest. If the lower layers have composted, use this on the garden. Mix everything else together well. Add water if it is dry, or add dry material if it is soggy. Replace in the bin and leave to mature
The HOT heap route
  1. If you have the energy, give the heap a good mix several times. Gather enough material to fill your compost container at one go. Some of this may have been stored in a cool heap and have started to rot slightly. Make sure you have a mixture of soft and tough materials

  2. Chop up tough items using shears, a sharp spade (lay items out on soil or grass to avoid jarring) or a shredder
  3. Mix ingredients together as much as possible before adding to the container. In particular, mix items, such as grass mowings and any shredded paper, which tend to settle and exclude air, with more open items that tend to dry out. Fill the container as above, watering as you go
  4. Within a few days, the heap is likely to get hot to the touch. When it begins to cool down, or a week or two later, turn the heap. Remove everything from the container or lift the container off and mix it all up, trying to get the outside to the inside. Add water if it is dry, or dry material if it is soggy. Replace in the bin
  5. The heap may well heat up again; the new supply of air you have mixed in allows the fast acting aerobic microbes, ie those that need oxygen, to continue with their work. Step 4 can be repeated several more times if you have the energy, but the heating will be less and less. When it no longer heats up again, leave it undisturbed to finish composting

A hybrid route

There’s nothing wrong with doing a bit of both. Fill your heap as you create waste (as for the cool method), then turn it when you have time. This will help it heat up. You can turn it as much or as rarely as you please – the more often you turn the heap, the quicker your compost will be ready.

When is it ready?

Compost can be made in as little as six to eight weeks, or, more usually, it can take a year or more. In general, the more effort you put in, the quicker you will get compost.

When the ingredients you have put in your container have turned into a dark brown, earthy smelling material, the composting process is complete. It is then best left for a month or two to 'mature' before it is used. Don't worry if your compost is not fine and crumbly. Even if it is lumpy, sticky or stringy, with bits of twig and eggshell still obvious, it is quite usable. It can be sieved before using if you prefer. Any large bits can be added back into your new compost heap.

How Long Does It REALLY Take To Make Compost?

It’s the question on everyone’s mind as they start composting: when will I get to use my compost? 

Frustratingly, there isn’t a simple answer. You could be lucky enough to have finished compost in less than a month, or you might need to wait a whole year or longer. 

Some factors influencing how long it takes for organic wastes to become black gold are out of your control (like the weather). However, there are lots you can do to speed up composting results. For example, why wait 12 months or more for your compost when you could have it in half that time or quicker? 

I’ve been experimenting with different composting techniques for years. I am about to share the must-know tips and tricks I’ve discovered. 

How Long Does Compost Take To Make

Making compost can take as short as a few weeks or as long as a year or two. Different composting methods, types of organic waste, and weather conditions either speed up or slow down results. Carefully built and maintained hot compost systems give the quickest results. 

Phases Of Composting 

Suppose the conditions are just right for aerobic (with oxygen) composting. In this case, organic wastes will go through three phases as they decompose:

The Mesophilic Phase

You’ve just built a compost heap that offers composting creatures (bacteria, fungi, and creepy crawlies) everything they’ll need to perform at their peak. Your compost is about to enter the mesophilic phase. The mesophilic composting team tackles the task of decomposing your organic wastes.

At the start of the process, the compost’s temperature is about 50°F. Then, as the mesophilic composting team breaks down the organic wastes, they produce heat, raising the temperature. 

Within a few days, the heap warms up to about 115°F, and the compost moves into the thermophilic phase.

The Thermophilic Phase 

During this phase, the heat-loving thermophilic composting team goes all out to break down the organic wastes. The team decomposes wastes at quite a rate, letting off great heat as they work. As a result, the temperature in the heap soars to about 140°F. 

After two weeks or so of fast, fiery work, the team runs out of things to decompose, and their work intensity eases. The temperature in the compost then drops to what it was in the mesophilic phase. Finally, the thermophilic team hand over to the mesophilic squad to finish the composting. 

The Maturation Phase  

With temperatures in a pile back in the range of 50 to 115°F, the mesophilic composting team continues breaking down what’s left of the organic wastes.  

The team works slowly and steadily to get the compost plant-friendly. The maturation phase is the longest, lasting several months. 

How Long Does It Take To Make Compost In A Pile 

It can take anything from three months to a year or two to make compost in a pile. 

The one- to two-year time frame is for organic wastes you dump and leave to break down without your help. 

You can cut the composting time to a few months by getting involved (I’ll give you pointers later in this article). 

How Much Time To Make Compost In A Compost Bin 

Making compost in a bin is quicker than making it in an open pile because the bin holds heat for faster results. 

Making compost in a bin can take two months (with your dedicated help) to about a year (if left to nature). 

How Long Does To Make Compost In A Tumbler 

You should get quicker results making compost in a tumbler than in a bin or open pile. If you take your compost tumbling seriously, you can have finished compost in under a month. 

Tumblers speed up the composting process in two ways: making it easier for you to turn the compost and retaining heat and moisture inside the container. 

You’ll find aerated compost tumblers like this one that will make the process more efficient. (Amazon)

Signs That Your Compost Is Ready:

You can tell your compost is ready by its look, smell, and texture. 

Finished compost looks like dark-brown, rich soil with few pieces of organic matter you can recognize. It feels fine and crumbly. And it smells like fresh earth after a thunderstorm.

Want another way to tell whether your compost is ready? Try this test: seal a handful of compost into a resealable plastic bag and put it aside. Three days later, open the bag and smell inside. A sour smell shows that the compost needs more time to mature before adding it to your garden.  

Smells earthy and sweet? It’s ready!

What Will Make Compost Break Down Faster

Now for everyone who’s waaay too impatient to wait a year (or even two!) for their compost, here are some guidelines for faster results. 

How to Hurry Composting Along:

The secret to fast composting? Heat. Remember that ideal 140°F temperature during the thermophilic composting phase, where heat-loving composting creatures are revved up and working like crazy to decompose organic wastes? That’s the temperature you want for your compost till the bulk of organic wastes has broken down. 

There are 3 basics to boosting composting results:

  1. Balance your nitrogen-rich greens and carbon-dense browns. Many composting experts recommend using three-part browns to one-part greens. However, getting this ratio right might be tricky, so just make sure you have at least an even mix of browns and greens in your compost.  
  2. Get your compost’s moisture level feeling similar to a wrung-out sponge. Aim for 40 to 60% water (you can check moisture levels with a compost moisture meter – Amazon). 
  3. Turn your compost regularly to give the composting creatures the air they’ll need to flourish. (If you’re using a tumbler, spin it about three times a week. Composting in a bin or pile? Use a fork or spade to turn your compost once a week. However, if it becomes soggy, add straw or shredded newspaper and turn it more frequently.)

More steps to supercharge your composting: 

Note: compost shredders are probably the most satisfying gardening equipment you’ll ever own! I recommend something like this powerful electric shredder. (Amazon)

Bonus Composting Hacks To Try 

So, you’ve balanced your greens and browns, you’re keeping your eye on your compost’s moisture level, and you’re turning it when it needs a good airing. But is there more you can do to get those composting creatures fired up?

Yes, you could give compost activators a go!

Compost activators are supplements you add to your compost for faster results. You’ll find all sorts of activators, from synthetic and natural ones at the store to ones right there in your backyard.

These are my top picks:

Something else that might give you better composting results is a gadget called a compost aerator. This nifty compost tool takes some effort out of turning your pile, upping the chance you’ll do it regularly!

Compost aerators come in two designs: a corkscrew style (best for light compost) and a plunger style (for heavier loads).

The last month of summer is coming to an end. The autumn season is about to begin. The garden and the garden will be “decorated” by heaps of dry weeds, leaves and plant debris. Where to put them? And the first thought is born - to burn. But a prudent owner will not burn such "wealth". All plant debris can be easily and quickly turned into organic fertilizer. There are several ways to quickly get organic fertilizer for garden crops through aerobic (fast) composts. They will be discussed in this article.

Advantages and disadvantages of fast composts

Aerobic composts have a number of advantages over traditional ones:

Aerobic composts are not without drawbacks. The laying of material for decomposition should be disposable and with a wide variety of plant waste. The laying of one leaf mass of fruit trees or only the tops of cucumbers, tomatoes, potatoes or other crops can slow down the composting process due to the increased carbon content or quickly “burn out” with excessive release of excess nitrogen.

What does it take to make good quality quick compost?

The high quality of quick compost is ensured by the variety of materials used for composting. In addition to the examples below, you can use all the waste from the garden, garden and surrounding wastelands.

In addition, making quick compost requires containers that can be easily moved from place to place. As a rule, multifunctional cling film bags of 120-150 (up to 200) kg or liters are used. But boxes of the same volume, lined with foil from the inside (to preserve moisture), bags made of other materials are also suitable.

A smaller volume is unprofitable, the raw material in it quickly dries up, and fermentation practically stops.

Important! Quick compost bins must be free of holes and openings.

The main condition for the preparation of high-quality quick compost - loose laying of the source material. Why is fast compost called aerobic? Due to the loose laying, the waste contains an increased amount of oxygen, which accelerates the decomposition/fermentation of the starting material.

Quick compost is prepared at least 2 times a year - usually in spring (but also in summer) and in autumn.

Spring laying of quick compost

In spring, the components of the future compost are evenly placed in the prepared container in layers (10-15 cm): weeds, tops, foliage of fruit trees, legume stalks, mowed grass, small pieces of turf without soil and other waste (sawdust, shavings, paper).

If available nearby, you can add the green mass of storage plants: comfrey, nettle, mustard, rapeseed, legumes, etc. salt" each layer).

It is even more effective to shed each layer of the starting material with the working solution of the Baikal EM-1 plant extract. If the components are very dry, they are slightly moistened before processing with EM-1 (humidity should not be higher than 50-60%).

Preparation "Baikal EM-1" or another composting accelerator can be purchased at any garden store. The extract contains several dozen (up to 80) strains of beneficial soil microorganisms that actively suppress pathogenic microflora and, with the help of beneficial ones, ferment organic waste into humus compounds, the elements of which are available to plants.

Filled containers are crushed and tightly tied or sealed with adhesive tape, the boxes are tightly covered with foil. The temperature in the container rises to +40°C, which contributes (along with fermentation) to the death of helminth eggs, seeds of most weeds, and pathogenic microflora. Of course, part of the beneficial microflora also dies, which is restored when it enters the soil.

If possible, ready-made compost can be spilled with EM-1 working solution 2-4 days before direct use, covered and applied to the soil after the scheduled time.

The process of fermentation of plant residues in quick compost lasts 1-3 months, and the compost is ready for use both during the growing season and for the autumn preparation of the soil for the next season.

Autumn laying of compost is carried out after complete harvesting, leaf fall, withering of the ground mass of vegetable and garden crops, greenhouse crops

Autumn laying of quick compost

. Stems of eggplant, tomatoes, dry weeds and other dense waste (bark, small branches, everything unnecessary, but organic) are laid in the bottom layer (10-15 cm) in the container. They will serve as drainage, increase aeration of the entire laid mass at low temperatures.

You can do without drainage. Grind the mass of plant waste on a shredder or manually with a hatchet, secateurs and fill the containers. The laying and processing of the material is the same as in the spring. Tie / seal the filled container tightly and take it to the basement or other non-freezing place - in regions with frosty winters, in the south - the containers are left on the street.

By spring, you will have loose, rotted compost that can be used in garden beds, when planting fruit bushes and trees, transplanting indoor flowers, fertilizing winter gardens and greenhouses.

Quick Compost Conveyor

Some gardeners (my friends, for example) have adapted to making quick compost with a continuous conveyor. Somewhere in a secluded corner (behind the house, barn, outbuilding), one or two 200-liter barrels are installed on bricks. On the side of the barrel below, near the ground, they make a door 20x25 cm (so that a shovel enters).

All vegetable and even food waste is placed in the barrel. Sometimes they are slightly compacted, more often they are slightly crushed. From above, water with a working solution of EM-1 or another "composting accelerator". The top of the barrel is covered with a film or a lid. The moisture content of the weeds in the barrel is maintained at 60%, for which the material is moistened or the barrel is left open for some time in the rain.

The fermented mass settles and, as necessary, new portions of plant waste are thrown inside and again literally sprinkled with an accelerator. After 1-2 months, the first portion of the compost is raked out through the lower door, the upper ones remain for fermentation. Two barrels on 4-6 acres are enough to keep the site clean and without autumn bonfires.

If the area around the house is large, there are free areas and huge amounts of plant waste, then fast or aerobic compost can be obtained in large quantities by the same laying of plant waste, but in stationary heaps or compost pits.
