A Wormery is a very simple but highly effective (and environmentally friendly) method of turning dead organic matter (such as cooked and uncooked food and kitchen waste) into a superb high quality worm cast compost (Vermicompost) and a nutritious liquid feed (leachate), which you can use in your garden and around your home.
Worm compost, like that produced by our Wormeries, is often referred to by the experts as ‘black gold’ as it really is the best and most nutrient rich you can get. A Wormery is an expertly acclaimed method of obtaining this ‘black gold’ worm compost, as well as reducing the amount of waste sent to landfill at the same time!
There are two main types of Wormery available and choosing between them is not much more than personal preference. All of our Wormeries work well from a technical perspective. They all do the same job and do it very well, but you may find one is more suitable for your needs than the other. Additionally, you will need to consider size and location.
The two types we offer are our Classic range of “all-in-one wormeries” (The Original, Junior & The Midi Wormery) and “the multi-tray system” Tiger Wormery.
The Original Wormery is the first ever commercially available domestic Wormery and has remained our best seller for a very long time (although it has gone through considerable development, improvement and refinement over the years). With its “all-in-one” design, the waste and liquid is all self-contained inside the bin, with an internal drainage platform separating the solids from the liquid and allowing you to catch and tap-off the leachate liquid feed.
It works well because the worms are ‘surface-feeders’. That means that even as the top section of the bin (where the solids are) fills, the worms tend to remain close to the surface – turning the waste into compost which they leave lower down. That means that emptying it is relatively straightforward when full. You simply trowel off the top few inches and put this to the side. Empty the worm compost out from underneath. Then pop the top few inches which you have put to the side back in the bin at the bottom.
Our “multi-tray system” (Tiger Wormery) removes this element of initial separation by using multiple trays to house the compost and waste. Each tray has a perforated base which allows the worms to move freely between them. You start off feeding your food waste into the bottom tray and as each tray fills, the worms move to the waste in the next tray upwards, leaving behind compost as they work their way up through the trays. So, by the time the worms have moved up to the top tray, the bottom tray should be ready to harvest and can simply be removed and emptied (before being placed back on top). It’s a bit like a game of ‘hands on top’!
So, you can see that each Wormery works in exactly the same way, but the method of harvesting the compost is different. Whichever Wormery you think will be easier for you to use is the one to go for and if you’re still not sure then you might be reassured by the fact The Original Wormery has been our bestseller for nearly 20 years!
It varies by the size and capacity of the Wormery, but all of ours are designed to take the majority of the average daily waste produced by its user. The Junior Wormery, for example, is designed for single person use and it will cope with the average food output of a single person. The Original Wormery is designed for family usage of, say, 4 people.
We invented the first commercially available Wormery 20 years ago and we even devised (and trade-marked) the very word ‘Wormery’ as it relates to composting. With this pedigree we proudly continue to offer simply the best range of great value, but high-quality Wormeries on the market today.
Our products have received independent acclaim over the last 20 years and we hold thick files of unsolicited customer testimonials which we are very flattered to receive and our customer service team are very highly experienced in resolving any issues or answering any questions you might have before or after you buy from us.
Apart from being the inventors, and thus to some extent the experts, and apart from offering an unrivalled range of Wormeries, we also offer the best value in the country and, remember we supply Tiger Worms!
A Wormery will divert your cooked and uncooked food waste, along with things like shredded newspaper, cardboard tubes, tea bags, egg cartons etc… Etc… away from landfill. In the UK, about a third of what we throw away is food waste which could otherwise be composted in a Wormery. In fact, we throw away something in excess of 7 million tonnes of food waste and peelings every year.
Not only that, a Wormery is also giving you something useful back. The highest quality compost you can get and a liquid feed which you can use to feed indoor / outdoor plants.
The best place to keep your Wormery is anywhere with a relatively stable temperature that is out of direct sunlight and preferably frost free. Most people keep their Wormery in their garage or next to the back door. A shed is also a popular location for a Wormery – you can also keep it indoors if you feel confident enough – and have space under a worktop or similar.
Worms operate year round, but they work best within the temperature range we humans tend to feel comfortable in.
Whilst worms will eat fish, we generally advise against it as it can get smelly quickly – a Wormery is usually not smelly at all. Small quantities of cooked meat however are fine.
Try to avoid using acidic foods in quantity such oranges, lemons and limes and the peel. The worms find acidic conditions uncomfortable. We supply all our Wormeries with an ‘anti-acid’ lime mix which helps to neutralise an acidic environment.
Other than that, pretty much all your cooked and uncooked food waste can be added straight into a Wormery, although cutting up thick fibrous waste such as broccoli and cauliflower stalks can be helpful.
Essentially it is a gentle form of calcium which reduces the acidity. Most food waste is mildly acidic and worms thrive best at a broadly neutral pH (7). A small handful sprinkled over the surface every 4 to 5 weeks will keep the conditions sweet. Crushed up eggshells (which are essentially calcium oxide) have the same effect.
There are 28 species of earthworm native to the UK and of these 3 are particularly suitable for composting. We strongly believe that Eisenia Fetida (or the Tiger Worm) is the best at the job. Essentially it survives in a wider variety of conditions and has a better appetite so deals with more food waste.
Other suppliers of worm bins use Dendrobaena, which is more widely available (and significantly cheaper) they are widely used by anglers as bait.
If they are the small red wriggly worms rather than the mineral soil dwelling earthworm (lob worm = lumbricus terrestris) the simple answer is yes. That said there should be no need to as we provide plenty to start with and they breed well in a Wormery.
Tiger Worms typically live for between 6 months up to 2 years.
No! This is a myth. It is possible one half of the worm may survive (but not definite), but you definitely won’t end up with two worms.
No. The great thing about worms is that they breed rapidly. If the environment in the Wormery is good for the worms they will breed well and will renew themselves so you shouldn’t need to reintroduce new worms. However, should you have a disaster and need more worms we can supply them in any quantity.
Nope. Worms are ‘clever’ with their breeding in that they will never overpopulate. They regulate their reproduction based on their environmental conditions, the space they have available and the food supply. Pity mankind hasn’t learnt this trick yet!
It depends on the type of Wormery you have. From a home-made or poorly made Wormery escapees are likely. Our Original Wormery has been designed to keep worms in as it is a fully sealed unit, but it is possible you might have some ‘escapees.
As the worms settle, they explore. This is perfectly normal. Losing a few worms is nothing to be particularly worried about, there are enough worms supplied to continue breeding.
Once the Wormery has been established and the worms have settled it provides them with their ideal environment and conditions. The worms are in an excellent and near ideal environment inside a dark, cool, Wormery, so they won’t want to get away even if they could.
The most likely reasons for the failure of a Wormery are the following:-
1) Overfeeding in the early stages
The worms need a little while to settle in and the food waste you add needs to partly decompose naturally before the worms are able to eat it. The first few weeks are the slowest and you should generally only feed a couple of handfuls a week when you first set it up. Once the worms are established and the food is in the correct state for the worms, you can increase the throughput.
2) Conditions get too wet
If the food waste in the Wormery gets very soggy and wet, then this can cause problems for the worms. With the weight of the water in the waste the waste becomes compacted and the air is pushed out of the waste. Worms need air. Signs of this are as follows. You might find they try to get away from the food waste, they will be at the top of the wormery and on the sides. You may find the worms have disappeared, they could be in the sump, if this is the case, it is likely the worms have drowned in the liquid in the sump. The sump should be drained every week. It may be necessary to tilt the wormery forward to drain if any solid matter has dropped into the sump. Please note, to open the tap, you need to turn the tap handle through 180 degrees to get the tap fully open.
It is an easy problem to solve, however. If the waste is looking wet (example), if you took a handful and squeezed it hard, if water runs out between your fingers it is too wet (damp/moist is good!) then simply shred up some extra newspaper or cardboard egg cartons and mix this thoroughly into the Wormery right down to the base plate or bottom of the tray. This will soak up the excess moisture, help aerate the compost, and return the Wormery to the normal operation.
3) Conditions get too acidic
This can be a problem if you add a large amount of acidic food waste such as citrus peel and / or conditions get waterlogged. Pot worms (enchytraeids) are tiny thread like worms that resemble a piece of white sewing thread a few millimetres long. They occur quite naturally and are harmless – in fact they do the same job as the Tiger worms. However, they thrive at a lower, more acidic pH than is ideal for the tiger worms. The proliferation of these pot worms is a sign of acidity – so if this occurs add a handful of the lime mix and combine it with the points above when the waste gets to wet.
Flies should find it rather difficult to get into your Wormery, however Wormeries can sometimes provide a good breeding environment for them if they are inadvertently introduced with some waste.
If you do end up having a problem with flies you can use an organic flyspray to kill their lifecycle. Instructions on how to deal with this are provided in the instruction booklet.
All of our Wormeries are provided with very comprehensive, easy to follow, instructions which contain hints and tips on successfully operating your Wormery.
If the instructions are followed, this is unlikely. But if you do feel your Wormery is not working properly – don’t panic. We would be happy to help you with any issues you may have – simply call us on 01462 429 765 and we can troubleshoot and advise as necessary.
A handful of waste takes just a few weeks to compost. However, you need to build up a good amount of compost to make harvesting it easy and worthwhile. Typically, it takes around a year to fill the Original Wormery with compost (with The Tiger Wormery you obviously harvest each tray more frequently). This is because most of food waste is liquid content which is released from the food and comes out the tap as the concentrated liquid feed.
This is typically within around 10 – 12 weeks. Though it could be quicker, or longer, depending on the amount and type of food you’re putting in and the time of year (or rather prevailing weather and temperature). Once the liquid starts to come through you generally tap it off every 3-4 weeks.
Yes, the feed should be diluted with 10 parts water prior to being used.
The liquid feed is multi-purpose and can be used on indoor / outdoor plants, flowerbeds, vegetable patches or on your lawn.
A Wormery is almost an odourless process because the food is consumed by the worms rather than left to decompose. Therefore any strong odour is eliminated by the worms before it has a chance to occur. If you stick your head inside a Wormery – you may notice a ‘composty’ sweet smell or even an earthy chrysanthemum or tomato plant smell.
No problem at all. A well established Wormery should be fine left for around a month. Simply add some food waste before you go and leave the tap open with a container underneath (just to stop the build up of liquid feed) and enjoy your holiday! The worms will look after themselves.
This is a common question after compostable nappies have received increasing press over the last few years. Technically, the worms can indeed turn nappies into compost, but the problem comes with size and quantity. If you were to compost all your nappies, the Wormery would very quickly become full and the worms would unfortunately not be able to cope. One or more of our excellent Garden Composters might be better for this job.
The simple answer is yes – but be careful. Waste and bedding from most herbivores e.g. rabbits, hamsters, gerbils etc. is fine.
However we do not advise adding waste from meat eaters such as cats and dogs which is more unpleasant and carries a risk of the toxocara virus. We offer a purpose-made “Pet Poo Convertor” Wormery which is designed to deal with that sort of waste.
The correct plural of the word Wormery is Wormeries, though some people do use the term Wormerys.
If this is what you wish to do, we wish you good luck! Designing a Wormery is notoriously difficult to ‘get-right’ and we’ve unfortunately seen lots of examples of poorly made Wormeries going wrong and ending up as a big mess.
It is unfortunate but we are increasingly seeing ‘experts’ advising people on how to build Wormeries at home but putting no thought into drainage / airflow / etc… Because they want to jump on the ‘go green’ bandwagon.
If you wish to give it a go, we do supply a DIY Wormery kit which will provide you with the worms, bedding and anti-acid lime mix you need.
This is not necessary or a routine operation as it is for a garden composter. However you do need to dig into it occasionally to check all is well. Also if it gets very wet and waterlogged you will need to thoroughly mix in dry cardboard and shredded newspaper.
