Master Greenkeeper John Quinn is the author of Performance Bowling Greens, and several other titles on Greenkeeping, Club and Business Management.
Each of the grass plants in our green is akin to a little factory where Carbon Dioxide and Water are broken down and converted to a sugar based plant food that can be used immediately to fuel the plant's growth processes or converted to starch and stored throughout the plant for future use.
The main difference between the two groups is the way in which they photosynthesise or produce food for themselves. The first product of photosynthesis in cool season grasses is a 3 Carbon sugar molecule so these grasses are commonly referred to as C3 grasses. In warm season grasses the first
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.
The soil food web has become an increasingly popular term in greenkeeping and bowling green management. The problem-solution-problem, or symptoms approach to greenkeeping has been exposed as fundamentally flawed by the diminishing list of available pesticides now available to turf managers. Is there a better way to manage greens...yes. And the extraordinary discovery is that a greenkeeping program that focusses on the green as an eco-system is fully compatible with producing tight, natural turf dominated by the fine perennial Fescue and Bent grasses.
When fungicides are used repeatedly, they don't just suppress disease temporarily; they erode the very microbial networks that would naturally keep disease in check. This explains why many greens find themselves caught in a cycle of recurring outbreaks and escalating chemical inputs.
