The Best Worm Farm Supplies

Our List of Worm Farm Supplies Will Make Worm Farming Even Easier!

Composting is a growing trend among the environmentally conscious and for a very good reason! Around 30% of everything that we throw away is organic, and therefore recyclable. Vermiculture – or raising worms to help compost our waste – is an easy effective solution of reducing waste. It diverts organic waste from ending up in landfill and repurposes it into rich compost, fueling new life in our gardens. This article aims make the process of owning and maintaining a worm farm easier by providing you with a list of worm farm supplies to help you on your way.

Essential Worm Farm Supplies

Find A Composter For Your Worms

There are plenty of good quality, affordable worm composters on the market today, each with it’s own pros and cons. You’ll find several reviews on this site of the most popular worm bins to help you find the right composter to suit your home. Our Buyer’s Guide can help make the process of choosing a worm bin easy, or alternatively, you can choose to make your own at home.

Whether you decide to make your own or purchase an existing product, you’ll find that maintaining the worm farm is relatively easy and inexpensive. Just make sure that it is large enough for the amount of compost you wish to produce, and that light can’t pass through the container. Worms thrive in the darkness and flee from the light naturally, so you don’t want to put them under too much stress.

Source Your Worms

Once you have your worm bin all setup, you’ll need to go about finding suitable composting worms to fill it with. There are thousands of species of worms in the world, but not all of them are suited to composting. Ideally, you want worms from the epigeic family that naturally inhabit topsoils and feed on organic matter. 

The most common and widely available species in the US and Canada is the Red Wriggler (eisenia fetida), followed by the European Nightcrawler (eisenia hortensis). You can purchase a pound of worms (usually around 1000 worms) from a number of vendors around the country, which should be plenty to get you started. Your worms will multiply and reproduce to suit the conditions, so will likely end up with many more!

Uncle Jim’s Worm Farm, based in PA, is a well renowned supplier of quality Red Wriggler worms for composting. They also sell European Nightcrawlers and ship to most States and select international countries. 

Worm Farm Supplies: Bedding Material

Creating a cozy home for your worms will require the use of a suitable bedding material to let them get settled. Coconut coir makes the perfect bedding material as it is rich in carbon, helps with moisture retention, is pH neutral and 100% organic. Mix it with a bit of soil and shredded newspaper to make a great bedding for your worms as they settle in to their new home. We recommend letting your worms settle for about a week in the bedding before you start adding your organic waste.

Additional Worm Farm Supplies to Make Life Easier

Now that you have the essential worm farm kit needed to begin vermicomposting, you may like to obtain some of the following items to help you with the ongoing maintenance of your worm bin. Of course, these aren’t essential and you can get by without them, but they can certainly help you keep your worms happy so that they work at the optimum level. Some of the most common worm farm problems can be fixed by simply using some of the items listed below.

pH/Moisture Meter

Worms need a moist environment in order to survive. They also require the acidity to be between 6.5 and 7, aka neutral. If your worm farm is too dry, or too acidic, you will find that your worms won’t process your food waste, or worse still, won’t survive. The same can be said for worm farms that are too wet (worms can drown) or alkaline (pH between 7 and 14). Fortunately, you can get meters that will measure one, or both of these quantities, giving you immediate feedback as to the health of your worm farm. They are relatively cheap and take all of the guess work out maintaining your worm farm. Why not try adding one to your worm farm supplies?


Worms don’t like extreme temperatures. If the temperature gets too low, they will start to eat less and not reproduce. Too high, and the same will happen. You may even see your escape from the composter, which can lead to a messy situation for you, especially if you keep your worms indoors. Ideally the temperature should sit between 60-80 degrees Fahrenheit for the best results. A thermometer can help make this an easy condition to monitor. Especially if you live in an area with high temperature differences throughout the year. You can buy a number of worm farm specific thermometers that use color-coded gauges for ease of use so you no longer have to guess the temperature!

Worm Blanket

It is good practice to use a blanket to cover the top of your worms and food scraps. This serves many useful purposes such as retaining moisture, protecting the worms from environmental conditions and keeping out unwanted pests. You can source your own worm blanket by making one out of hessian, or by laying a few sheets of damp newspaper over the top. However, for the best results, you can look at purchasing high quality worm blankets from many garden retailers. They often come with little handle to help you easily raise and lower the worm blanket when feeding your worms.

Electric Heating Mat

Most worm species prefer their habitat to be around 70 degrees Fahrenheit for optimal performance. Now, this doesn’t mean the ambient temperature needs to be 70 degrees, but rather the bedding itself. It’s still possible to own a worm farm even if you live in an area with below freezing temperatures in winter. Due to the heat released during decomposition, the temperature inside the worm bin is usually a few degrees warmer. If the worm bin gets too cold, you may see decreased activity from your worms. Worse still, if left unchecked, you may lose a lot of worms to particularly harsh winters. One mitigation strategy is to relocate your worm farm indoors to where it’s a bit warmer. Additionally, you can even place an electric heating mat underneath your worm farm for some added warmth overnight. A germination mat works great in this situation, even though it wasn’t specifically designed for worm farms.

Compost Aerator

Composting relies on oxygen in order for the decomposition process to work effectively. This is because it is an aerobic process (meaning in the presence of oxygen) as opposed to anaerobic. Anaerobic decomposition is what happens in landfill when organic material breaks down, causing the release of the powerful greenhouse gas methane. We want to ensure that doesn’t happen in our worm farms! It is therefore important to ensure the contents are well aerated, which can be a messy procedure if mixing by hand. A compost aerator is one handy tool that can help you aerate your worm farm with minimal risk of harming your worms.

Compost Conditioner/Dolomite Lime

As mentioned previously, acidic environments aren’t great for worms.  Adding compost conditioner or dolomite lime can help keep your worm farm healthy and pH neutral. Simply spread some conditioner or dolomite over your worm castings in a light dusting and then mix it into the soil. If your soil isn’t moist enough and you see some clumps of dolomite powder, simply give it a little spray with water and mix it in again. What you want to avoid, however, is letting your worm farm get very acidic and then adding a whole lot of conditioner in to fix it. Your worms won’t appreciate the rapid pH changes! Remember, prevention is often better than the cure.
