Beyond plant pests & diseases? Richard Higgins on how going 'beyond organic' could revolutionise horticulture

Season 4, Ep. 48

Good Gardeners International is a charity that since 1962 pioneered the no dig system in the UK, based on Sir Albert Howard's research on organic farming.


Richard Higgins became involved in 1995 after a formative trip to India and inspired by Howard, developed the HH-2 (Howard-Higgins Agricultural and Horticultural System) Waste Management and Horticultural System.


The HH-2 equipment reproduces specific fungi and bacteria that creates a sustainable habitat to enable the colonisation of the root hairs of plants giving them huge boots of previously unattainable nutrients. It claims, along with a unique, manure-based feedstock, to be able to renew degraded soils in one season. 


Adoping a no-dig appoach complements this as keeping the soil intact protects the "mycorrhizae, and that is the network that feeds the nutrients from soil into the root hairs of plants. So if you don't dig, that's preserved."


Higgins explains: "[HH-2 is] a composting system that breeds fungi, specific fungi and bacteria. Now, ordinary compost doesn't do that; this system does, and it's this fungi and bacteria that makes plants so resistant to disease. I mean, we already cured slug snails and caterpillars 30 years ago!"


Initially marketed and sold to amateur gardeners, "it's so popular and farming today is in such a problem with soil depletion and pollution in rivers, etc., that we've blast into farming. It applies to farmers as well as gardeners".


He says a focus on 'new varieties' has stymied research into how soil conditions can impact plant health. GGI has a demonstration farm where, he says, "we've got universities, colleges, agricultural colleges queuing up to come and see it, because people don't seem to know how to stop these common agricultural pests. We don't use any supplementary feeds like comfrey or rhubarb leaves in... no nets for the black fly, white fly, carrot fly, you know. We don't use any nets at all and we have none of these problems."


Higgins discusses startling claims for treatments that could reverse the effects of ash dieback and says he is in the process of liaising with scientific institutions, agricultural research stations and soil scientists with a view to carrying out trials and scaling up production for wider distribution to amateur, and professional growers.

  • 23. The wonderful world of sustainable, small scale and peat-free flower farming - with Georgie Newbery

    28:41||Season 6, Ep. 23
    Georgie Newbery is chair of Flowers From The Farm and founder of Common Farm Flowers, one of the first of the new artisan flower farmers to establish in the UK.A small scale flower farm and educator, the farm, established in Somerset in 2010, grows up to 100,000 stems annually without the use of chemicals,Newbery is set to feature at RHS Chelsea Flower Show this May in the Great Pavilion where she will present the first representation of a flower farm at the show, showcasing Ranunculus, also for the first time.She hopes the display will "advocate for flower farmers" and inspire them to perhaps start growing flowers themselves. One of her Chelsea funders is peat-free compost supplier Sustain - and Newbery, as a peat-free flower farm from the start, says there is no excuse for using peat "just because it makes life easier for me". She also believes she can "demonstrate that it's easy to grow peat-free".While she fully understands the difficulty and cost for larger commercial growers of switching their nurseries to peat-free systems, she says "everything we do, we make a choice... we choose to learn how to use other kinds of compost, because it's possible, and it's not breaking the planet".Newbery talks about the operation she runs at the farm, how she manages to grow successfully without chemicals, and her experience with peat-free compost, products, techniques and adaptations. She revels in the idea of the flower farm as a reservoir of life and biodiversity that will act as "innoculation stations" that, come the end of the world, could seed the desert green landscapes surrounding them.As well as growing flowers Newbery runs workshops and demonstrations on propagation and seed-saving, such as how to design a cut flower patch. Weddings and funerals account for most of her cut flower sales. Customers there usually come through word of mouth, she says, often "because they want something that has come from a garden".Newbery has a distinctive philosophy of business and in mentoring small businesses. She encourages "the stepping away from the 'more for the sake of more' model. The key, she says, is to work out "what your 'enough' is". If you work out what your minimum need is, modest or luxurious, "whatever it is...then work out how to build a business that will pay for it". And she is fierce in her support of other small business owners who want to make a good living supplying a high quality product without endlessly having to expand. Asked about her "flowers of the future" she says "seed sovereignty" should be the focus, with locally-grown seed, adapted to UK conditions more likely to provide "bigger, stronger" plants compared to imported options.A new edition of her book "The Flower Farmers's Year" is out in May 2026.

  • 20. How do we understand and reach today's plant consumer? - Michael Perry hosts a IPM Essen Panel on effective plants marketing

    35:41||Season 6, Ep. 20
    Bruce Harnett of Kernock Park Plants, Megan Green of Hayloft Plants and Yvonne Marquenie of Plants & Flowers Foundation Holland joined <i>HortWeek</i> new plants writer Mr Plant Geek Michael Perry on a panel at IPM Essen to discuss how the horticulture industry should understand today’s plant consumer.They discussed: 1. The peat-free and sustainability dilemmaThe transition to peat-free media remains the industry’s most "hot-button" issue, particularly in the UK.Kernock Park Plants (KPP) went 100% peat-free in 2024 and Bruce Harnett says that sustainability (biomass, water self-sufficiency) is a moral choice, even if the "commercial advantage" is currently unclear.Panellists agreed that, for consumers to fully switch, peat-free media must be equal to or better than peat. Currently, some "staunch" growers still believe peat performs superiorly.But while sustainability is a growing concern many consumers still "turn a blind eye" when price is a factor.2. Innovation vs. "Trust Erosion"Should the industry stop introducing new plants? The consensus: Innovation must have purpose.KPP uses a rigorous trials process to ensure only "the best of the best" hit the market. Introducing novelty without value leads to "trust erosion."Plants like Salvia ‘Hot Lips’, Lavender ‘Hidcote’, and standard Rosemary remain dominant because they are reliable. Consumers value the "tried and tested" for mail-order success."TikTok Plants": Novelties like the TomTato or "family" apple trees resonate with younger, online audiences, but the industry must distinguish between viral aesthetics and long-term garden performance.3. Multi-platform marketingThe panel discuss approaches and strenghts of different platforms:YouTube: ideal for practical "how-to" guides.Instagram/Pinterest: use aspirational/inspirational imagery.Facebook: focus on community and storytellingMeanwhile Matthew Perry raises concerns about influencers who focus on garden aesthetics rather than plant health. The panel stresses the need for authentic voices over "unattainable" glossy imagery.And Megan Green says that, for Hayloft, 75% of business is now online, though the physical catalogue remains a valued tactile experience for a core demographic.4. The "Holy Grail" of 'engagement'Green highlights the power of visual merchandising—linking the plant, compost, and pot in one display to remove customer friction.QR codes on labels and improved storytelling are seen as the "Holy Grail" for garden centres to provide info at the point of purchase.Research shows search behavior is often driven by nostalgia (especially in herbs) and the desire to care for others (gifting).5. Reaching the Next GenerationYounger consumers represent the future but are the hardest to recruit due to a lack of gardening space and lower spending power. Engaging them requires shifting from a "critical" focus to a "positive attitude" shift, making gardening feel attainable rather than a luxury chore.In summary, the industry must balance the marketing "pull" of new varieties with the "push" of sustainable production, ensuring that every new introduction builds consumer trust through reliability and climate resilience.
  • 18. Turf Wars: the ups and downs of running a sports turf business, with CutCrew's Jack Churchman

    42:53||Season 6, Ep. 18
    In an era of AI fakery and fake news, star of the CutCrew YouTube channel, Jack Churchman has built his grounds maintenance business through authenticity and it has served him well. Eschewing the 'easy' money of kit sponsorship, he has won respect, credibility and work by sticking to his principles and maintaining standards.Inspired by his mum and grandad who were keen gardeners, he got his first job at a golf course at the tender age of 9. After a spell in the military he used his spare time to work for free on gardens and golf courses during the pandemic and gradually turned it into a business. Blessed with a ferocious work ethic, tenacity, resilience and a restlessness, he now at least partly attributes to ADHD, Churchman built his landscape maintenance business from the ground up and he is candid about the challenges of finding finance to grow his company with "no mummy and daddy to lend me £100k or whatever".  As much as YouTube has served Churchman, it has drawn some unwanted attention, tipping off burglars looking to move expensive machinery to competitors trying to sabotage CutCrew by trolling, misrepresenting and even stalking him. Despite the dramas, however, he maintains "the benefits far outweigh the negatives".But interspersed with laughs and self-deprecation that have made Churchman such a YouTube phenomenon, is frank discussion of the challenges of running a business, negotiating competition, issues with late payment, spreading of risk, pricing, cost pressures and being responsible for people's livelihoods. The podcast is also littered with tips and hard-won wisdom on how to win clients. And his advice to prospective entrepreneurs?: "Chase the thing you like, know and love from the beginning".Find the CUTCREW LTD | Grounds Maintenance & Tractor Action YouTube channel here: https://www.youtube.com/@cutcrewltd
  • 17. Are UK garden centres underperforming? Dries Jansen from Garden Center Advice on data that could boost your yield per sqm

    33:49||Season 6, Ep. 17
    View slides and Vodcast edition at https://www.hortweek.com/article/1944940In this edition of the HortWeek Podcast, Matt Appleby spoke to Dries Jansen of Garden Center Advice talking about how to optimise garden centre operations for profit through layout, assortment, and realisation.Jansen began his career as an analyst at Intratuin in the Netherlands, working with 56 stores and €250 million turnover. He used trends and data back then to identify predictable patterns.But now, working alongside leading garden centre architect Fred de Rijcke, Jansen has combined data from HortWeek's exclusive annual Top 250 Garden Centres with insight from the garden centre markets in the Netherlands, Germany, France, and Belgium, to create a comprehensive decision-making model for the UK market. The data analysis system maps annual turnovers against store area, various variables and individual store offerings, proximity to population centres and other key metrics. Combining these data sets he finds an 'average' yield per sqm that all garden centres can be measured against. Individual stores can be indexed to understand how they are performing and whether they may benefit from further investigation to find ways to improve that performance. Stores identified with 'potential' to improve are profiled individually to assess their performance in various metrics, eg. ambience, service, price etc. and action points can be generated to help boost turnover.Jansen refers to slides and images during the podcast - to view these or see the video version of this podcast, CLICK HERE
