Belle Richardson used to have a recurring problem on her smallholding in Yorkshire. She would put a hosepipe into a trough, bucket or other container, get distracted by children, animals or another job, then come back to find water everywhere.
It happened, in her words, “over and over again”.
So she decided to solve it. The result was Seal Stop, a device that clips onto the side of a container and automatically shuts off the water when it reaches the required level. Simple to describe. Considerably less simple to create.
Belle spent five years taking the idea through development. There were 3D-printed prototypes, tooling changes and a lot of fine tuning to make something that could work reliably across very different water pressures. By the time we spoke at Glee, Seal Stop had already been soft-launched through her website, customers were buying it and she was continuing to improve the product from their feedback.
You could reasonably say the product was ready.
But garden retail introduces another test. A product can work perfectly well and still not be ready for a buyer, a retail fixture or a customer seeing it for the first time.
That distinction came through strongly when I listened back to two separate conversations we recorded at Glee. Belle gave us the founder’s view of taking a new invention towards wider distribution. Tony Kersey, GIMA’s Membership Ambassador and a former buyer at Sainsbury’s and Homebase, gave us the other side of the picture: what retailers and newer suppliers need from each other if innovation is going to become commercially useful.
The gap between those two perspectives is where this gets interesting.
A good idea still needs a retail story
Tony talked about the need for “newness” in retail. Garden centres need fresh products, fresh reasons for customers to visit and points of difference that keep categories moving. He also sees more collaboration between retailers and suppliers than he did earlier in his buying career, particularly around innovation, sustainability and first-to-market development.
That is encouraging for anyone bringing something genuinely new into the sector. But newness, by itself, is not a reason to list a product.
A buyer has their own business to think about. They need to understand where the product fits, who is likely to buy it, what it might replace and why their customer will choose it. They will also be thinking about margin, supply, rate of sale and the amount of support the launch is likely to need.
None of that makes the product idea less important. It simply means it has to survive contact with commercial reality.
This is where some product launches become difficult. The people closest to the innovation have spent months or years concentrating on whether it can be made, whether it works and how to improve it. Then, quite suddenly, the question changes from “does it work?” to “why should somebody buy it?”
Those questions overlap, but they are not the same.
Five years of knowledge can make the story harder to tell
Belle has no shortage of things she can say about Seal Stop. It saves water. It saves time. It’s made in Yorkshire, designed to be durable, works across a wide range of water pressures, and can be used with watering cans, troughs, dipping tanks, ponds and other containers. It has even survived being run over by a tractor.
All of that is useful evidence. The difficulty is deciding which are the most compelling things to share.
This is a familiar marketing problem, the curse of knowledge. The more we know about a product, the harder it can be to remember what it feels like to encounter it without any of that information. We naturally want to explain the development, the technology, the evidence and every useful application because we know how much work sits behind them.
The customer is usually starting somewhere much simpler.
In Belle’s case, the immediate appeal may be that you can leave a watering can or trough filling without coming back to a flood. That is an ordinary, recognisable frustration. The water-saving benefit then makes the solution more valuable, particularly as water use becomes a bigger issue.
I like the order of that. Sustainability is not being attached to the product as a worthy afterthought. It is inherent in what the product does, but the customer also gets a practical benefit they can feel immediately.
When we spoke, Belle was careful not to overclaim it:
“Well, no greenwashing here. It’s all genuine. It was built on a sustainable core because that was really important to me.”
That is the point where product development becomes proposition development. You stop asking only what is true about the product and start deciding which truth gives the customer the most compelling reason to notice, understand and want it.

Proof is more useful than enthusiasm
One thing Belle did before trying to scale into garden centres was a self-funded soft launch through her own website.
That decision gave her something many early-stage products do not yet have: evidence from people who had actually paid for it.
She could see how customers were using Seal Stop, what they liked, where they found other applications and what they wanted next. She talked about enjoying the phone calls where customers would explain how the product fitted into their lives and suggest ideas for future development.
For a founder, that is useful product research. And for a retail buyer, it also gives valuable insight.
There is a significant difference between telling a retailer that you believe people will want something and being able to show that people are already buying it, leaving reviews and finding uses you had not necessarily anticipated.
It doesn’t remove the risk entirely. A successful direct-to-consumer soft launch is not proof that a product will automatically perform in a garden centre. The audience, price context, merchandising and buying behaviour can all have an impact.
But it gives the buyer something to assess, not just vague optimism.
For smaller brands in particular, that evidence can be disproportionately valuable. An unfamiliar supplier is asking a retailer to take several bets at once: on the product, on the proposition and on the business behind it. Anything that reduces uncertainty helps.
Retail readiness is another stage of development
This is where Tony’s interview and Belle’s interview begin to join up.
Tony described the amount of support newer GIMA members often need. Many are small or medium-sized businesses with good products but limited experience of the garden trade. His role is partly to help them find the right people, ask the right questions and understand where support is available. GIMA’s buddy scheme takes a similar approach, matching businesses with experienced, non-competing people who can help with areas such as marketing, presentation or general commercial guidance.
Belle had found some of that support through GIMA, but also through Will Armitage, who she described as an important mentor as she learned her way around the garden industry. Winning GIMA’s Seed Corn Fund then arrived at a useful point in the journey. She had garden centre conversations progressing and wanted to invest in display units that would help sell the product in store. She described the award as meaning “everything”.
There is a temptation to treat this kind of support as something around the edges of innovation: networking, introductions, awards and useful contacts once the serious product work has been done.
I think that understates it.
Being able to manufacture a product is one milestone. Being ready to supply retail introduces another set of practical and commercial demands. The price and margin need to work. Packaging has to explain an unfamiliar product quickly enough. Case quantities, lead times and supply need to be realistic. The claims need to be robust. The display has to justify its footprint. The retailer needs some confidence in how people will discover the product and why they will choose it.
For a founder who has spent five years solving the engineering problem, none of those things may feel as intellectually difficult as making the mechanism work across 0.5 to 5.5 bar of water pressure. Commercially, though, they can determine whether the invention ever reaches enough customers to matter.
An outsider can see a problem insiders have stopped noticing
There is another part of Belle’s story I would not dismiss too quickly. Before becoming an inventor, she spent 11 years as an NHS radiographer. She was not a product manager searching a garden category for a gap in the range.
She had an annoying problem in her own life and wondered why there was not a better way to solve it.
Coming from outside a category can create obvious disadvantages. You don’t know the buyers, the trading calendar, the accepted margins, the supply conventions or all the mistakes other people have already made. Belle’s own story shows why experienced mentors and industry contacts can be so helpful.
But insiders carry their own disadvantage. Familiarity makes existing conventions feel natural. We know why products are made in a certain way, why ranges are structured as they are and why retailers expect particular things. Over time, it becomes harder to notice the frustrations that a customer simply experiences as absurd.
A fresh observation without commercial understanding can remain a clever invention that never finds a viable market. Commercial experience without fresh observation can keep producing increasingly competent versions of things people already have.
The interesting territory is where the two meet.
The founder story should support the proposition, not replace it
Belle also has the kind of founder story marketers would be delighted to inherit. An NHS radiographer on a Yorkshire smallholding gets fed up with overflowing troughs, spends five years inventing a solution, manufactures it locally and starts taking it into garden retail. There is perseverance, personality, British manufacturing and a genuine sustainability story all wrapped around the product.
It’s good material to work with. But I would still resist making the founder journey carry too much of the sales job.
The story can make a business more interesting and give people reasons to care about who is behind it. It can add trust, character and memorability. What it can’t do is rescue a proposition that has never made the product’s usefulness clear.
The customer standing in front of the fixture wants to understand the usefulness first. The deeper story then gives that simple proposition more substance.
The same applies to British manufacturing, sustainability and technical proof. They can all strengthen the decision, but we still have to decide what leads and what follows.
Good product marketing is partly an exercise in hierarchy. Not because the other information is unimportant, but because attention is limited and somebody has to choose what leads.
So when is a new product actually ready?
Listening to Tony and Belle’s separate interviews together made me think we use the word “ready” rather loosely around innovation.
A product can be technically ready. The product performs and manufacturing can begin.
It can be customer ready. Real people understand it, buy it and get a useful result.
And it can be retail ready. The proposition is clear, the commercial model works, and the product has a fair chance when it appears in someone’s store.
But those things don’t always happen at the same time.
That is not a criticism of the product or the founder. It is simply a reminder that invention and marketing solve different parts of the same commercial problem.
Seal Stop started with a frustration that was easy to recognise and difficult to solve. Belle did the hard work of turning it into a functioning product. The next stage has involved customers, industry contacts, mentoring, GIMA and retailers helping to expose a different set of questions.
For anyone preparing a new product for Glee or an important buyer meeting, I think the useful question goes beyond “is it finished?”
The better question is whether somebody who was not involved in creating it can quickly see why it deserves to exist, why a customer would care and why a retailer should make room for it.
That is a different definition of ready. And commercially, it may be the more important one.
This article was inspired by two separate conversations recorded for The Underground Podcast at Glee: one with Tony Kersey, Membership Ambassador at GIMA, and another with Belle Richardson, founder of Seal Stop and winner of GIMA’s 2025 Seed Corn Fund. Tony brought the perspective of an experienced retail buyer now supporting suppliers through GIMA, while Belle shared the experience of taking a new invention from five years of development towards wider garden retail distribution.
