The Wormcity Wormery 100 (4 Tray) is a compact stackable wormery designed for turning kitchen scraps into compost and liquid feed at home. Its four-tray system lets you add waste at the top while finished material develops below, with a built-in drainage tap for collecting excess liquid.
With a relatively small footprint and a starter kit that includes composting worms, bedding and worm food, it is particularly well suited to beginners, small gardens and patios. The main compromises are its limited capacity for larger households and the fact that full trays can become awkward to separate when harvesting compost.

Using the Wormcity Wormery 100
The Wormcity Wormery uses a four-tray stackable system, allowing fresh waste to be added above while the worms work through material in the lower trays. In practice, this makes harvesting finished compost easier than with a single-bin wormery. If you’re unsure how the finished material differs from ordinary compost, see our guide to worm castings vs compost.
Four-Tray Design and Capacity
The four trays provide up to 100 litres of composting capacity, which should be plenty for many small to medium households. The modular design also means additional trays can be added if you need more capacity.
The main limitation is that households producing larger amounts of food waste may still outgrow it, particularly if scraps are being added faster than the worms can process them.
Ventilation and Drainage
Ventilation around the trays helps maintain the airflow worms need while reducing the risk of the contents becoming overly wet or anaerobic.
A drainage tap at the base allows excess liquid to be collected rather than pooling in the bottom of the wormery.
Build Quality and Footprint
The Wormcity is made from recycled, UV-protected plastic and is designed for outdoor use. At approximately 43 × 43 × 105 cm, it takes up relatively little ground space, making it practical for patios, smaller gardens and other areas where a conventional compost bin may be too bulky.
Its tall design does mean you need enough vertical clearance to remove and rearrange the trays comfortably.
Starter Kit
One of the biggest advantages for beginners is that the Wormcity is supplied as a complete starter kit, including 500g of composting worms, coir bedding, worm food and instructions.
That removes much of the setup work involved in starting a wormery from scratch and means you can get the system running without sourcing worms and bedding separately.
Best suited to: Beginners and small to medium households wanting a compact wormery that includes everything needed to get started.
Wormcity Wormery FAQs
Yes. Its compact footprint means it can be used in places such as utility rooms, garages or other suitable sheltered spaces. As with any wormery, keeping the moisture and food balance right is important for avoiding unwanted smells.
Suitable materials include:
– fruit and vegetable scraps
– coffee grounds and tea bags
– crushed eggshells
– shredded paper and cardboard
Avoid adding meat, dairy products, oily foods or large amounts of cooked food, as these can attract pests and upset the balance of the wormery.
Feed the worms small amounts regularly rather than adding large quantities at once. Keep the contents moist but not waterlogged, harvest finished compost from the lower trays when required, and protect the wormery from direct sun and extreme temperatures.
This liquid is leachate rather than brewed worm casting tea, which is made separately from finished worm castings. Wormcity recommends diluting it with 10 parts water before using it around plants.
The starter kit includes 500g of composting worms, along with coir bedding and worm food. More worms can be added later if required.
Wormcity suggests around two months for a filled tray to turn into compost once the system is established, although temperature, feeding and worm activity can affect the actual time.
Finished worm castings can be used around vegetables, containers and garden plants as a nutrient-rich soil amendment.
Yes. The supplied worms, bedding, food and instructions remove much of the initial setup, while the stackable tray system makes it relatively straightforward to manage once established.
