In the spring of 2012, Cian Fitzpatrick stumbled upon a cluster of wild oyster mushrooms growing on a fallen beech tree near his family's farmstead outside Clones. That encounter sparked something. He spent the next two years reading everything he could find about mycology, attending workshops in the Netherlands and Hungary, and converting an old stone outbuilding into a makeshift growing room.
His wife Orla, a food scientist by training, saw the potential immediately. She brought rigour to what had been a passionate hobby, developing substrate formulations and sterile laboratory protocols that dramatically improved yields. By late 2014, Tarivoxa had its first commercial harvest: forty kilograms of grey oyster mushrooms sold to three restaurants in Monaghan town.
The name "Tarivoxa" itself comes from an old Irish dialect word loosely meaning "earth gift," which Cian found in the notebooks of his grandfather, a schoolteacher who collected local expressions. It felt right for a business built on drawing something beautiful from the soil.
From a single growing room to a multi-structure operation supplying restaurants and retailers across Ireland, each year has brought new challenges and achievements. Here are some of the milestones that shaped Tarivoxa.
Our inaugural batch of grey oyster mushrooms went to three restaurants in Monaghan. Forty kilograms harvested from a converted stone outbuilding with hand-built shelving and a second-hand humidifier.

Secured a Rural Enterprise grant through Monaghan County Council and built two purpose-designed growing rooms with climate control. Introduced shiitake and lion's mane to the range. Weekly output climbed to 200 kilograms.
Achieved Bord Bia Origin Green certification, confirming our sustainability credentials. This opened doors to larger retailers and food service distributors across Leinster and Ulster.

When restaurant demand dipped during global disruptions, we pivoted to home delivery across Ireland. The response was overwhelming, and direct sales have remained a core channel ever since. We also launched our on-farm shop.
Invested in a dedicated sterile laboratory for spawn production and culture maintenance. This gave us full control over our mushroom genetics and allowed us to begin experimenting with new varieties like maitake and nameko.

Tarivoxa now produces over 600 kilograms of fresh mushrooms per week across six varieties. Our team has grown to twelve people. We supply more than forty restaurants, ten farm shops, and hundreds of homes through our delivery service. And we are still just getting started.
Tarivoxa is more than two people. Our growing team brings together diverse skills and a shared commitment to producing the finest mushrooms in Ireland. Every person on this farm plays a part in what arrives on your plate.
Co-Founder & Head Grower
Cian oversees all cultivation and growing operations. His hands-on approach means you will often find him in the growing rooms at dawn, checking fruiting conditions and planning harvest schedules. He holds a certificate in Applied Mycology from Wageningen University.
Co-Founder & Lab Director
Orla manages the laboratory, quality control, and product development. With a BSc in Food Science from University College Dublin, she brings scientific precision to everything from substrate formulation to packaging design. She also leads our recipe development work.
Operations Manager
Declan joined in 2018 and quickly became indispensable. He coordinates the daily logistics of harvesting, packing, and dispatching orders. He manages relationships with our wholesale accounts and ensures every delivery meets our freshness standards without fail.
Customer Relations & Farm Shop
Sinead runs our on-farm shop and manages direct customer relationships. She handles online orders, answers enquiries, and organises our Saturday farm tours. Her warmth and knowledge of mushroom cookery make every visitor feel welcome.
Plus eight additional team members in growing, packing, and delivery.
Running a mushroom farm is an exercise in patience and attention. Fungi do not respond well to shortcuts. They demand the right conditions, the right timing, and genuine care. That philosophy extends to how we treat our land, our customers, and our community.
Every input we use has been chosen with environmental impact in mind. Our straw comes from farms within thirty kilometres. Our sawdust is a by-product of sustainable Irish forestry. Spent substrate goes back to local gardens as nutrient-rich compost. We use heat pumps powered by renewable energy to regulate our growing rooms, and our packaging is fully compostable. In 2024, we achieved carbon-neutral status through a combination of on-site solar panels and verified offsets with Coillte's native woodland programme.
We are part of the fabric of north Monaghan. All twelve of our employees live within a twenty-minute drive of the farm. We buy locally wherever we can, from the straw we use as substrate to the compostable trays we pack into. We host school visits throughout the year, teaching children about the science of fungi. And every December, we donate fresh mushroom boxes to food banks in Monaghan, Cavan, and Enniskillen.
Mycology is a field where new discoveries happen constantly. We invest in ongoing education, attending European mycology conferences, trialling new species, and refining our techniques each season. Orla collaborates with researchers at Teagasc on substrate optimisation studies, and Cian regularly visits specialty farms in Belgium and Italy to exchange knowledge and cultures. This commitment to learning keeps us at the forefront of specialty mushroom production in Ireland.

Varieties
County Monaghan's drumlin landscape, mild climate, and clean air provide an ideal setting for mushroom cultivation. The rolling hills, abundant rainfall, and spring-fed water supply all contribute to the quality of what we grow.
Our growing rooms are misted using water drawn from a natural limestone spring on the eastern edge of the property. This water is exceptionally pure, with low mineral content that prevents unwanted deposits on mushroom surfaces. We test it quarterly through an independent laboratory in Dundalk to verify its quality, and it consistently exceeds EU drinking water standards.
The county's drumlin geography creates a naturally sheltered microclimate. Winters are mild enough that our heat pump systems can maintain growing room temperatures with minimal energy input. Summer humidity levels rarely drop below 60%, reducing the work our misting systems need to do. The moderate Irish climate means we can grow year-round without the extreme heating or cooling costs that farms in continental Europe face.
In 2022, we installed a 25kW solar panel array on the south-facing roof of our packing facility. This system generates enough electricity to power our cold storage units, laboratory equipment, and lighting throughout the summer months. During winter, we draw from the grid but source 100% renewable electricity through our supplier. Our air-source heat pumps provide efficient climate control across all growing rooms.
We believe transparency builds trust. Our farm is independently audited and certified, and we are proud to work alongside some of Ireland's most respected food organisations.
Full member of Ireland's national food sustainability programme since 2018. Independently audited annually for environmental practices, food safety, and supply chain traceability.
Registered and compliant with all FSAI regulations for primary food production. Our HACCP plan covers every step from substrate preparation through to final dispatch.
Recognised member of the Good Food Ireland network, connecting us with like-minded producers, chefs, and food lovers who champion quality Irish ingredients.
Active research collaboration with Teagasc on substrate optimisation and waste reduction in specialty mushroom production. Contributing to scientific knowledge while improving our own methods.
We open our doors every Saturday morning for guided farm tours. Walk through our growing rooms, visit the laboratory, taste freshly harvested mushrooms, and pick up supplies from our farm shop. Tours run at 10:00 and 11:30 and last approximately one hour. Booking is recommended.
