DLF supports the scale and scope of top-level sport at Cranleigh School
While the challenges of managing the multi-sport surfaces at Cranleigh School may be akin to those faced by most in the education sector, here they’re on a mammoth scale!
With 248 acres of sports pitches, grounds and gardens to keep in quality condition year-round, the priorities when it comes to seed selection is reliability, versatility and tolerance for wear and tear. This, according to Deputy Grounds Manager Andy Burke, they’re achieving with mixtures from across the DLF and Johnsons Sports Seed ranges.
Cranleigh is one of Surrey’s leading co-educational independent schools and notes a number of leading public figures and some seriously sporty alumni over its 150+ year history. Its high sporting calibre is perhaps unsurprising given the scope of the surfaces available to pupils which includes 21 winter sports pitches, 8 cricket pitches and a 9-hole golf course. When Andy joined the school 9 and a half years ago, mixtures from the Masterline and Johnsons Sports Seed ranges were already used site-wide, and he goes on to explain why this has continued.
“In our environment, and with the sheer scale of facilities, our scheduling of operations and renovations has to be pretty strict which ultimately means we are often putting seed in the ground when conditions aren’t perhaps optimal. For example, in the Spring of 2022 we carried out extensive overseeding on our cricket outfields and winter sports pitches using Johnsons J4Turf and PM81 from the Masterline seed range. Then, despite seeing very little rain until the start of September, our grounds team were incredibly impressed that after a dormant period we saw strong growth and incredible drought recovery at the first drop of moisture. The result was quality playing surfaces that looked good and performed evenly.”
Johnsons J 4Turf and J Premier Wicket are used on the cricket outfields and squares, which host upwards of 250 games a year. “The turnaround and level of wear is intensive, but we’ve found this combination of mixtures withstands the high level of play, recovering quickly and coping with climatic conditions – be those dry like last summer or wetter as we’ve had throughout 2024.”
The cricket outfields are cut down to 16mm until the last game of the season, then will be left to grow to 32mm where they will then play a critical part in a packed rugby programme. “This is where the seed really gets tested as the demands of rugby will push wear tolerance to the limit! We’ve always found the strong bladed and deep rooting DLF and Johnsons mixtures can handle that, before being taken down to 26mm for football.”
Masterline PM81 is ideally suited to the renovation and repair of winter sports pitches, multi-purpose fields and racecourses. The 100% perennial ryegrass mix delivers outstanding versatility, sward density and year-round colour. Beside this, J 4turf and J Premier Wicket, Andy and the team are also using Johnsons J Rye Green on their golf greens and Masterline PM51 Greenscape as a general, high-performance mixture for landscaping and hard-wearing lawns.
He concludes, “It’s ultimately these mixtures that are the foundation to everything we oversee in our department and that year after year give us the quality and, importantly, the versatility to sustain such a high level of sport.”
