Downcast is back and improved

If a product’s real purpose is to kill earthworms then this is now illegal for turf application in the UK. It's always best to stay compliant with UK pesticide legislation, honest with your players and committee, and aligned with a longer-term view of soil health. That’s been the Bowls Central way since day one.
Downcast is a non-pesticidal liquid that deters surface worm activity and encourages it deeper in the profile. It doesn’t kill worms; it helps keep their good work (aeration, aggregation, nutrient cycling) where it benefits the soil without spoiling the playing surface.

Fusarium. Why It’s Getting Worse, and What to Do About It

Over the last few decades, routine applications of fungicides, high-salt synthetic fertilisers and ever-increasing topdressings of sand have left many UK greens biologically bankrupt. I see it time and again in soil analysis reports: textural classification coming back as just “Sand”. Very little in the way of silt or clay and sparse organic matter. No biological cushion.

Seaweed for Bowling Greens: Ancient Input, Modern Results

Beyond plant growth, seaweed feeds the microbial community that underpins a healthy green. Polysaccharides like laminarin and fucoidan stimulate beneficial soil microbes, improve aggregation, and enhance nutrient cycling.

Grass Root Defences: Leatherjacket control in Bowling Greens

Grasses employ a range of physical, chemical, and indirect defences to protect their roots from insect herbivores. Further research is needed to fully understand these mechanisms and to explore other potential defences, but meantime, we can take some of this knowledge and apply it now to our greenkeeping practices.

The thatch dilution delusion

The thatch dilution delusion...discuss. Can thatch be diluted? If so, is there any benefit in doing so? As with many aspects of modern greenkeeping that have been accepted as fact without evidence, the claims for top-dressing's ability to dilute thatch fly in the face of the science.
