About us

Maxstim is a scientifically-driven innovative organisation responsible for developing a powerful range of complex biostimulants. We are trusted around the world by progressive agricultural growers through to leading sports venues.

Our innovative research and development programme is driven by CEO Richard Salvage and our Chief Scientific Officer Dr. Colin Fleming. Our technical team has vast experience of field conditions in different climates. Together we understand what farmers and growers are looking for and what challenges they face. Our international presence enables us to offer support through soil analysis, diagnostics and on site field visits.

Our products are multi-sourced complex biostimulants that create a synergistic response from a wide variety of bioactive components. Each product is the result of innovative research and includes specific polyphenols and bioflavonoids, organic acids, plant based amino acids, carbohydrates,  ascophyllum nodosum and trace elements. This wide range of bioactive compounds have been engineered precisely to work synergistically for the most beneficial results.

We are delighted to have established ourselves with some key long term customers internationally. We are proud to be in demand from growers and farmers across the globe. This is supported by our growing network of highly regarded distributors.

What people say about us

"Maxstim has had a significant impact on our plants. Initial trials showed very clear differences within days of planting. The treated plants grew faster, filled the pots quicker and budded earlier. The flowers lasted almost twice as long as the control plants, as their stems were much stronger. Anyone with an interest in growing plants that look healthier, larger and hardier should seriously consider using this product."

Sheena | Horticulturalist | Rouken Glen Garden Centre

"I am happy with the results, the fruits are of good quality and I am very pleased that we have significantly increased our harvest."

Raimundo | Alberto Garcia Farms

"As we watched the trial progress, everything about the treated plants looked far greater than the control plants. Not only were they more robust, but their colouring and root mass were better too. What also took me by surprise was the weight of the treated plants; they had a much denser mass, which would make them hardier plants in our customers' gardens."

Manager | Gouldings Garden Centre

"Our field trial results on blueberries show that we can get the roots to develop much faster, nearly doubling the yield over five years. It’s not all about the yield - the berries are more uniform, larger, better quality with significantly higher BRIX values and a longer shelf life. Allin all, using Maxstim means growers will achieve a very significant increase in profit. Every grower will want Maxstim."

Peter van Dijk | Wijstwater Advies

"After the first two weeks, the plants treated with Maxstim were already looking healthier. They grew larger and had a better colour. Overall, they looked the better plants and sold almost immediately when we put them back on sale. We offer a full guarantee on all our plants and would be more confident with the treated plants being more resistant to any problems that could lead to customers bringing them back."

Colin Barrie | Manager | Caulders Braidbar Garden Centre

"I’ve never seen such a big improvement in such a short period of time; it’s amazing. I never get that much root growth in a whole year!"

Lee Evans | Head Groundsman | Millennium Stadium

"I love the Maxstim product! It does so much and all from one bottle. It gives me great roots, vibrant healthy plants with great sward and colour. The pitches cope really well with stress and recover very quickly."

Anthony Harry | Head Groundsman | Swansea Training Ground

"Maxstim has played a big part in thickening the foliage and we've noticed fewer divots too, enough scars to keep us busy but the decline in divots is noticeable. Maxstim has become part of our pitch regime both here and at our training facilities. I would recommend Maxstim and am looking forward to seeing the results next season from seeding."

Phil Fifield | Head Groundsperson | Fulham Football Club

"I incorporated Maxstim into my well established maintenance program some 18 months ago and I would have no hesitation in recommending it to my peers. It has definitely contributed to enhancing the plants ability to endure stress and usage, giving me a much more durable playing surface. I have now incorporated Maxstim into the program at Murray Park too."

David Roxburgh | Head Groundsman | Glasgow Rangers

"It soon became evident that the tomatoes I had treated with Maxstim were considerably larger, up to 20%, but with no loss of flavour. Earlier and more uniformed ripening was noticed too and general plant health was excellent. Based on the trial results I quickly started applying Maxstim to the whole farm. I’ve noticed Maxstim had a more pronounced effect with young developing plants and with fewer fruit required to get to the 450g punnet size, I’ve already built Maxstim into my budget going forward."
