Like most, the objective for James Cleaver – Course Manager at Stratford Oaks Golf Club – is to achieve year-round consistency when it comes to plant health and play quality. A steady, reliable nutrition programme has become a key part of that effort and, over the last 18 months, Suståne’s 5-2-4+Fe slow-release natural base fertiliser has played an increasingly important role.

Rounds are high at the private members club located on the outskirts of Stratford-Upon-Avon, with James and a team of six working hard to retain high performing greens despite high levels of wear and often challenging climatic conditions. To source an organic ‘base feed’ which would keep the greens healthy year-round and, in particular, provide a boost over the winter months, James spoke to Nathan Scarff at GBR Amenity. “When it’s wet in the winter and difficult to get a sprayer round, switching to a natural-based granular product meant fewer trips around the course and less reliance on spraying during those periods” says James. “After trialling Suståne’s 5-2-4+Fe in autumn 2024, we emerged in the spring in a healthier place which then encouraged us to up the applications to four or five times a year – focusing on the high disease pressure windows.”

Noting the success of their Suståne applications, James highlights one particular result which came following last year’s severe drought. “We had one green which really struggled without irrigation. I spoke to Suståne’s Russell Riley who suggested putting down some extra 5-2-4+Fe to help with the recovery and, interestingly, we’ve noticed that this is the only green which has emerged into 2026 disease-free. Obviously we can’t say for certain that Suståne is the sole reason but it’s the only thing that was done differently and something we’re looking to explore further.”

“Another great thing with this product is it doesn’t trigger a massive flush of growth like you get with some other fertiliser products. Application is also easy – the small prill quickly gets into the sward so, when applied in conjunction with predicted rainfall it doesn’t disrupt our mowing programme.” James continues, “I also appreciate the honest help and advice we get from both Nathan and Russell who actively encourage you not to over-apply products. It’s a refreshing change from the ‘more the merrier’ approach you get from some sales reps!”

5-2-4+Fe is the original Suståne formula, developed in 1988. Its all-purpose nature makes it ideal for a range of sports turf and landscape applications, providing a quick green up followed by long lasting slow-release organic nitrogen.
