Three generations of love for the land, a decade of dedicated potato farming, and one family's commitment to growing the finest spuds in County Cork.
Founded
Caladruo began with a simple idea and a pair of muddy boots. In the spring of 2014, Seamus O'Sullivan left his position at an agricultural supply company in Cork city and returned to the family homestead just outside Bandon. The 45-acre plot had belonged to the O'Sullivan family since the 1960s, when Seamus's grandfather Donal first purchased the land from a retiring dairy farmer. For years the fields had been leased to neighbouring farms for grazing, but Seamus had always felt they deserved more.
His wife Deirdre, a trained food scientist who had spent eight years working with Teagasc, shared his vision of a farm that could supply genuine, flavourful potatoes to people who cared about where their food came from. Together they drew up a plan, secured a modest start-up loan, and planted their first five acres of Rooster and Kerr's Pink seed potatoes that April. The early harvests were small, sold at the Bandon Farmers' Market from the back of their Land Rover, but the response was immediate and enthusiastic.
Word spread quickly among local chefs and food enthusiasts. By their second season, Caladruo was supplying three restaurants in Cork city and two independent grocers in Kinsale. The farm has grown steadily every year since, but the principles that Seamus and Deirdre established on day one have never changed: healthy soil, honest methods, and potatoes that taste the way they should.
Every decision on the farm comes back to these core values. They guide how we grow, who we work with, and how we treat the land that sustains us.
Healthy potatoes begin with healthy earth. We follow a strict four-year crop rotation, alternating potatoes with cover crops like clover and rye that fix nitrogen naturally and prevent soil depletion. Each autumn we spread composted farmyard manure from a neighbouring cattle farm, returning organic matter to the ground. We test our soil annually for pH, phosphorus, and potassium levels and adjust our approach accordingly. The result is living, biodiverse soil that produces potatoes with genuine depth of flavour.
We believe food is best when it travels the shortest distance from field to fork. The majority of our harvest stays within County Cork and the wider Munster region. We supply directly to restaurants, independent shops, and families through our farm shop and farmers' market stalls. By keeping our supply chain short, we can guarantee freshness, reduce waste, and build genuine partnerships with the people who eat what we grow. Many of our customers have been with us since those first market days in 2014.
Ireland has a rich potato heritage that stretches back centuries. We actively preserve older varieties like British Queen, Kerr's Pink, and Champion that have fallen out of favour with large-scale commercial growers. These potatoes may produce lower yields per acre, but their flavour and culinary qualities are exceptional. By maintaining seed stocks and growing these varieties each year, we help ensure they remain part of Ireland's living agricultural tradition rather than disappearing into history books.
We use integrated pest management rather than blanket chemical applications. Our crop rotation breaks disease cycles naturally, and we select blight-resistant varieties where possible. When intervention is necessary, we choose targeted, approved treatments with the lowest environmental impact. We monitor our fields daily during the growing season, catching problems early before they require heavy-handed solutions. This patient approach produces cleaner potatoes and a healthier ecosystem across the farm.
Caladruo is deliberately small. Seamus and Deirdre run the farm with help from two part-time workers and seasonal harvest hands drawn from the local community. This scale allows us to give personal attention to every row, every variety, and every customer. We know our fields intimately, recognising which corners drain slowly or which slopes catch the most sun. That level of knowledge is impossible on a 500-acre operation, and it translates directly into the quality of every potato we sell.
We welcome visitors to the farm throughout the growing season and host school groups each autumn during harvest. We believe that connecting people with how their food is grown builds appreciation and understanding that lasts a lifetime. Deirdre runs cooking demonstrations at local food festivals, and Seamus regularly speaks at Teagasc open days about traditional growing methods. Sharing knowledge keeps farming traditions alive and inspires the next generation of growers.
From a five-acre experiment to a 45-acre farm supplying customers across Munster, here are the moments that shaped Caladruo.
Seamus and Deirdre plant their first five acres of Rooster and Kerr's Pink seed potatoes on the family homestead near Bandon. The planting takes place in mid-April after weeks of soil preparation and chitting indoors. They invest in a second-hand single-row planter and begin what will become a lifelong farming partnership.
The inaugural harvest yields approximately 12 tonnes from the five acres. Seamus and Deirdre begin selling at the Bandon Farmers' Market, arriving each Saturday with crates loaded in the back of their Land Rover. The response from local shoppers is overwhelmingly positive, with many commenting on the flavour and texture compared to supermarket potatoes.
After tasting Caladruo potatoes at a local food event, three Cork city restaurants approach Seamus about regular supply. This marks a turning point for the farm, providing steady weekly orders and the confidence to expand planting to 15 acres. Two independent greengrocers in Kinsale also sign on as regular customers the same year.
Caladruo expands to its full 45 acres and introduces heritage varieties including British Queen, Champion, and Lumper to the rotation. Deirdre begins collaborating with the Irish Seed Savers Association to source authentic seed stock for these older cultivars, ensuring genetic authenticity. The farm shop opens on Saturdays for direct collection.
Caladruo is nominated for the Cork Food Producer of the Year award, recognising the farm's contribution to the local food economy and its commitment to traditional growing practices. The nomination brings increased visibility and a wave of new wholesale and retail customers from across the Munster region.
Today Caladruo supplies over 200 regular customers including restaurants, shops, and families across Munster. We grow eight distinct potato varieties and continue to experiment with additional heritage cultivars. Plans are underway for a dedicated education space on the farm where school groups and aspiring growers can learn about soil science, crop rotation, and traditional Irish potato culture.
Behind every potato is a person who cared about it from seed to harvest. Here are the faces of Caladruo.
Founder & Head Grower
Seamus grew up watching his grandfather Donal work this same land. After studying agricultural science at University College Cork and spending a decade in the industry, he returned to turn the family homestead into the farm it was always meant to be. He walks the rows every morning, checking leaf colour and soil moisture, and still hand-picks the first early potatoes each July.
Co-Founder & Quality Manager
Deirdre brings scientific rigour to everything the farm does. Her background in food science at Teagasc means she oversees soil testing, post-harvest handling, and storage conditions with meticulous care. She also manages customer relationships, develops recipes for the farm's loyal following, and runs cooking demonstrations at food festivals throughout Cork and Kerry.
Farm Assistant
Ciaran joined the farm in 2020, fresh from the Clonakilty Agricultural College. He manages the mechanical equipment, handles earthing up and spraying schedules, and coordinates the seasonal harvest crew each autumn. Born and raised on a sheep farm near Dunmanway, Ciaran brings youthful energy and a deep understanding of West Cork farming conditions.
Caladruo Farm sits on gently sloping ground just south of Bandon town, where the Bandon River valley meets the rolling hills of West Cork. The soil here is a mix of clay loam and alluvial deposits, naturally fertile and well-suited to root crops. The area receives generous rainfall throughout the year, typically around 1,200mm, which keeps the ground moist during the critical growing months of May through August without the need for artificial irrigation.
The Gulf Stream influence gives this part of Ireland mild winters and moderate summers, with frost rarely occurring after mid-April. This extended frost-free period allows us to plant earlier than farms further north and east, giving our earliest varieties like Queens a head start. The farm's south-facing slopes capture maximum sunlight, while mature hedgerows of hawthorn and blackthorn provide natural windbreaks that shelter the crops during summer storms.
We consider ourselves stewards of this land rather than owners. The hedgerows support nesting birds, the field margins are left wild for pollinating insects, and the composting cycle returns nutrients to the soil rather than depleting them. When Seamus's grandchildren eventually take over, we want the ground to be richer and more productive than when we started.

Regular Customers
Caladruo is more than a potato farm. We see ourselves as part of the wider Bandon and West Cork community. Each autumn during harvest season, we welcome local school groups to the farm for hands-on learning days. Children get to dig potatoes by hand, learn about the plant lifecycle, and take home a bag of freshly harvested spuds for their families. These visits have become a much-anticipated annual event for several primary schools in the area.
We are regular participants at the Bandon Farmers' Market, the Midleton Farmers' Market, and the Skibbereen Food Trail. Deirdre runs seasonal cooking demonstrations showing simple, delicious ways to prepare each variety, from colcannon and boxty to roasted baby Queens with sea salt and butter. These events are as much about conversation and connection as they are about selling potatoes.
We also donate surplus produce to the Bandon Community Food Bank and support the West Cork Farming Heritage project, which documents traditional agricultural practices in the region. Farming has always been a collective endeavour in Ireland, and we are proud to carry that tradition forward.
We welcome visitors throughout the growing season. Get in touch to arrange a farm tour, ask about wholesale supply, or simply learn more about what we do.
