While many assume surface-casting worms are shallow dwellers, the reality is more complex. Lumbricus terrestris, for example, is a deep-burrowing anecic worm—it constructs vertical burrows up to 2 metres deep but returns to the surface to feed on organic debris, which it pulls into its burrow.
Nitrogen is essential to turfgrass performance—it drives growth, colour, and density. But too much or too little, applied at the wrong time or in the wrong form, can do more harm than good. Spikes of growth followed by periods of stress are all too common with traditional nitrogen sources, especially on fine turf where consistency is king.
Applied monthly during the growing season at label rates, BioActive Yucca keeps moisture availability in the optimal zone for healthy, stress-resilient turf. It can also be used strategically before or during periods of drought to buffer the turf against rapid desiccation.
As climate change reshapes weather patterns, Dollar Spot—a turf disease once rare in the UK—has become an increasing concern for greenkeepers. This article explores how rising temperatures and humidity levels have created favourable conditions for the spread of Clarireedia jacksonii, the fungus behind Dollar Spot. Learn how to identify the disease's distinct symptoms and discover effective management strategies, including the use of Trichoderma fungi and integrated pest management practices, to combat this new challenge and help your green recover from an outbreak. Stay ahead of the curve and maintain your green's health by understanding the full impact of Dollar Spot and adapting your turf care approach.
Localised Dry Patch typically rears its ugly head in June in the UK, but by then it is way too late to do anything about it. Once your green is displaying the large brown patches of desiccated grass and powder dry soil beneath, no amount of watering or wetting agent will bring it back fully this year. Now is the time to inspect your green and deal with it permanently.
