Learn moreSierrablen Plus is a premium range of controlled-release fertilizers that provide consistent, reliable, and long-lasting nutrition for turf. It uses advanced coating technologies to ensure a steady supply of essential nutrients over an extended period.
The key difference is granule size. Sierrablen Plus has a finer granule, making it ideal for shorter-cut turf like tees and fairways. Standard Sierrablen has a larger granule and is better suited to turf mown above 12mm, such as outfields and general landscaping.
Sierrablen Plus uses advanced coating technologies to gradually release nutrients over 3 to 5 months. This ensures a steady supply of essential nutrients to the turf, reducing the risk of nutrient leaching and excessive growth flushes.
Benefits include up to five months of precision nutrition from a single application, consistent nutrient release patterns, and effectiveness in all weather conditions. This helps save time and money while maintaining healthy and strong turf.
